Unlock the Truth: Is Marshall JTM Studio ST20 the Best 20w Tube Amp?

[@MarkGallacher-m8m]

Excellent review……….as always. Please don’t stop making content. Your reviews and the work you put into them are a breath of fresh air. The small minded people who think differently are jealous of you.

[@tonymckenzieofficial]

Thanks ... appreciated comment and thanks for watching.

[@marshall]

Thank you for the fair and in-depth review, Tony!

[@tonymckenzieofficial]

No worries!

[@BreauxBobby]

Thank you for the in depth review like no one has done for this amp. It's a beauty. Please keep the videos coming. I really enjoyed your take on things.

[@tonymckenzieofficial]

Thanks for watching and great that you gained from this review.

[@SirVicc]

Love your in depth reviews, Tony. Don't let the numpties and KZbin get you down. Got your vid in my recommendations, and glad I did. Really loving this amp, just wish the pricing in Canada was closer to the pricing in the UK.

[@tonymckenzieofficial]

Yes prices seem high USA and Canada for sure. Distro's...

[@samaitcheson7057]

Great review Tony. I really like your no BS approach and in depth reviews. Keep them coming. IMO Marshall are absolutely nailing it with these studio amps and evidently surpassing so called boutique amp builders in terms of build quality. Made in England too, as Marshalls should be.

[@tonymckenzieofficial]

Glad you liked this review. I was surprised that after this review Marshall 'subscribed' to me! So I guess they liked it. I like the Studio series too and cheap enough (at least in the UK) to be affordable. I would love to see one of the more modern Marshall amps in the 20w format too like a 410HJS (preferably) but unlikely they could use the (JS) part at the end. Might cost a little more but I'm sure that amp would also sell well. There are some good boutique amp makers, but generally the costs involved are very high (generally made USA way) with little real advantage over the Studio series and I think they know it. Thanks for the post and for watching. I'm thinking of 'revisiting the Marshall JVM410HJS head as that offers so much by way of tones and its so different than the 410H version...

[@aipsong]

Tony, I am sure that you have a very appreciative and large group of people that will find your videos even if they are not notified. On my very new Mac, with a fiber optic network, many notifications don’t turn the bell icon red as they used to. Being subscribed to your channel means that I can always find your new videos in my subscription history. I can understand your frustration but I hope you will find time now and then to make my (our) days brighter!! Cheers!!!

[@PeterDad60]

Tony, this is the among best amplifier review I have ever watched here on KZbin. I have been watching your video's for a couple of years now so today I have subscribed. I wish to encourage you to continue to educate people about amplifiers as you talk about how they sound and also about how they are built and that is something very few people do. Please continue as your efforts are greatly appreciated (and needed). I am 73 years of age and my favorite guitar amplifier is the Marshall JTM45 /2245, but for some reason I have had bad luck with them and all 3 JTM45's that I purchased brand new had issues within 10 days so I returned each of them. I still want the JTM45 sound as it inspires me. If I can get that sound from the new Marshall JTM Studio ST20 I shall purchase one immediately. If I need the Xotic SL Drive Mini overdrive pedal to get that sound using the JTM Studio ST20 then I shall get both immediately. Or if only the Marshall JTM45 can get that sound I shall try again and get another new JTM45. I am of an age that I want to be satisfied with my sound as I play all day and for several hours every day and evening of my life. I am not a wealthy man but the price for me is worth it. My playing is something close to a jazz, blues, rock with a touch of metal thrown in. I have no need to play extremely loud but I still like a long sustain note available when I want to play one. I actually play at a softer, moderate volume and Allow the tone to carry me away. Marshall JTM45/2245 has that tone at any volume I want. I love the tone. To me the JTM45 has a strong bottom end tone and when I play I dial up the bass while lowering both the mids and treble controls on the amplifier to get the sound that I like best. I also like to play through my Marshall Origin Full stack because two 412 cabs (the top 412 is a slant or type "A" and the bottom is the type "B" 412 cab) can really distribute the sound all throughout my living room/studio. I had a Marshall 1960A and 1960B Full stack years ago but sold it when we moved. I am settled in now in our own home but my finances have changes and now I have the newer Marshall Origin 412A and Marshall Origin 412B Full stack Still not too bad at all! Now, having heard your playing at the end portion of this video I can say that my playing is similar to yours as played here. Well, your notes have a certain amount of more treble than mine but otherwise our styles are close enough. - Peter age 73

[@PeterDad60]

One other thing I prefer to bias my own amps and Stuart ukguitarampguy has made a KZbin video "How to bias Marshall JTM45 MKll Model 2245" and that was a god send for me. If you have the time could you make such a "How to bias" video for the new Marshall JTM Studio ST20 amplifier? Please sir? Tony, I shall be so very thankful for any consideration you may give my request. Thank You again! - Peter age 73

[@tonymckenzieofficial]

Peter - forget the age thing... you're as old as your mind allows you to be - there are far too many that cite age on YT and that frankly ageism seems pretty common. Of course, like me you are a wealth of knowledge from practical experience and that is in my opinion important - and when someone posts like you have its all to easy to see that... I'm nearly as old, but you know what, it's all about what you like to do. I still work too, but because I WANT to... these values all mater Peter and its great to read your post - clearly you love the Marshall JTM45 :) This little ST20H I showed is a very good product - its clearly not a top end amp, but my guess is that for the money it might be hard to find another equivalent. The price might be higher if you're in the USA of course... Marshall are cheaper here. But it IS worth at least trying one out - indeed as I did. I do play lots of styles from older stuff, blues, rock heavy rock and some metal but I do have a number of amps and I tend to use those depending on exactly what tones I want at the time. The Boss Blues 2 pedal also had a good sound with the ST20H I thought. Ah the 1962 A and B :) I tend to have the 1962A cabs but ha I have too many. The origin cabs are great value for the money I think. In any case, let me know how you go on with it all - I would love to know what you end up with :).... and thanks for the post and for watching.

[@rickycompton2610]

Glad to see you back Tony, what a great in depth review as you always Do, Nobody does reviews like you, I’ve said before and I’ll say it know you can’t beat UK Marshall build Quality yes they have a few Quirks here and there with the JCM 2000DSLs and TSLs but nothing that can’t be sorted out by replacing a board, I think they nailed the JTM 45 tone in a smaller package,Thanks for the review Tony!!

[@stillpist]

Replacing the board is a pretty big deal. Hardly belongs in the 'sorting things out' category.

[@tonymckenzieofficial]

@stillpist - it might be a very big deal in some countries... I completely agree, but my board for the TSL100 when I did it was about £120.00 which to be honest was a really good deal. But my TSL really was worth spending the £120 on it... they are great recording amps when they are operational. Thanks...

[@stillpist]

I guessing that was the price of the board itself and you did the work yourself? I'm not a tech and am no way comfortable doing that sort of thing. I would imagine if you brought it to a shop it would cost 3 or 4 times that. Mostly I'm just frustrated that amp companies make engineering decisions that lead to failures when they could literally spend a few dollars more in production to fix some of these glaring problems. Seems like planned obsolescence to me and that's in part why I bear my name.

[@billydunn]

[@glennmichaelthompson4112]

This is the first time I want to buy a Marshall amp since I sold an old mid 60's 50 watt half stack several years ago. The JTM Studio seems so versatile. I have to check the prices here in Canada. It would be nice to get the speaker cabinet as well... it's not like I have a lot to choose from personally. Thanks for another great review, Tony! I hope there's enough interest to keep you doing these... without the hassles. Take good care.

[@tonymckenzieofficial]

Seems expensive there... :( and thr transformer like all Studio models here supports 230v only (no other primary). Thanks for watching and the post too.

[@yobaby14]

Thanks for this review Tony. The normal reviews of "Oh, look...it makes noise!", got old rather quick since I was even more interested about the build quality, like whether the resistors were on or off the board. As you pointed out, having the resistors lifted off the board goes hand in hand with reliability. Cheers!

[@tonymckenzieofficial]

I agree... I did watch a couple of other reviews and they never really cover what I might want to see - but I get that. My reviews are content focused to what I might want to know myself, and its the reason I started reviewing back in about 2010 on YT. I have made them ever since, but it is harder now with less real new stuff out there, unless you like Tonex and that type of stuff. I found that not very good and the software let it down... a more common trait these days with the digital stuff from what I see. Yes the resistors for all the Studio amps (at the very least) are all off the board. I have seen so many that are hard fixed to the PCB... which IMO is a seriously not good way to have cement resistors. Marshall even lift the 1/2w ones off the board... Others generally don't. It says so much to me... Thanks for watching.

[@yobaby14]

@@tonymckenzieofficial From my understanding, when Marshall first started using PCB's it came with a learning curve. They upgraded the quality of the PCB's and stood off the resistors as a result, and now have a quality PCB product. Unfortunately, there is another well known brand that hasn't implemented Marshall's "Lessons Learned". I love the EQ of the JTM's and am soooo tempted to get one. But at the same time, I can closely emulate that EQ with my Quilter Superblock UK & US that I run in stereo into a Marshall cab. The stereo rig also takes up less space on my end table/cabinet that's next to my chair too. LOL

I've seen so many videos about this lately. Yours and Tone Preist's are the only ones that didn't feel like paid ads. Good review as always ! I'm surprised you gave it a good review, actually. I'm kind of spoiled and have been building my own hand wired amps, and I've kind of gotten snobby about pcb amps.. Glad to see this one is well made. It really looks amazing, too. Good first offering from the new owners of marshall

[@tonymckenzieofficial]

Well the amp is probably better than what many think re the JTM name. Nothing wrong with them, but I did feel that this JTM Studio is different sounding to me. It can do a lot and so I refer guys to check the Marshall playing review as that has it all covered in general. It was better than what I envisaged tone wise. All Studio's are PCB as you might know, but they seem reliable and well enough made, but only time will tell. Will they be running in 50 years? THAT is the question :). This review was entirely financed by me, and Fair Deal is mentioned because I like them... I bought my Gibson Jimmy Page from Gary way back at musical exchanges in about 1996 or thereabouts... and FDM are brillaint at Marshall gear... thanks.

[@Wooburnmusic]

Was getting tempted but I'm not sure that PCB mounted valves and controls are a good thing, my pair of 79 Marshall mk 11 master volume combos 50w have gigged almost non stop over the decades and not one problem so far, if we are to purchase PCB mounted gear then we might as well go for Marshall MGs, they are PCB wired not good and I'm sure that their lifetimes are limited, electrical engineers are finding good work with some of the marshall PCB boards.

Outstanding overview as always. You've inadvertently served to muddy up the waters over which amp I'd like to get , ha!

I do keep coming back to these guys and the 20w JCM800s they have, they both sound great.

My reviews are always as I find the gear, and I can't say more than from personal experience. Glad you liked the review, by far most do, but its probably 'fan boys' that on some reviews create sarcasm and not cool comments which is always a problem on 'social' networks. Me? Social networks frankly I dislike because of exactly those reasons. The good guys are great and the less good ones are basically not nice people, have awful channels (nothing on them) and criticize until the cows come home. You're one of the good ones :) and thanks for hanging in there and watching.

[@Brett6165]

Hi Tony. I love that you take the amp apart and walk through things like lead dress, circuit boards and transformers, and build quality. I think you are the only one that does that - and its super cool. Being an amp nerd, I love to see those kinds of details and it makes a huge influence on me dropping real money on one of these expensive models. I agree with you about some of the boutique amps being lax on some of the things like putting power resistors snug to the board, instead of raised up for airflow, and provoking burnt circuit boards failures. There are a couple of things I would love to see in your reviews. 1. A side by side comparison between these MINI style heads and the original big heads - do they really sound the same or close enough? 2. An objective measure of relative volume - which is super important if you play live gigs with drummers versus at bedroom volume levels. My rational is that its super hard to gauge useable volume (especially in non-master vol amps) for things like clean, breakup, and heavy distortion based on videos. It would be cool is to measure things like what is the max volume level can you hit cleans tones with before the amp goes from clean to breakup (xxx dB, assuming no drive pedals). Anyway - thanks so much for your review - keep doing it, I really appreciate your work!

[@tonymckenzieofficial]

Great post and thanks for taking the time to do it. I have a Marshall 1959 Hand Wired head, but trying to compare that with the studio ST Vintage would be VERY hard to do. Sure I can use the loading on the 100 watt to bring down the volume, but that alone changes the tone and feel. All I can say is that the 1959HW through a 4x12 Marshall cab turned up really can't be compared in the way you mention (no matter what any of them out there tell you). Having said that, the ST does sound like the 1959 but unless you have the same volumes and drive (not really possible) it won't sound exactly the same or feel the same, but it IS inspirational and certainly gives the feel that can inspire of that there is no doubt. While I really like the JTM ST20 shown here, really I prefer other Studio models because of the style I actually play. I could use pedals etc. but I tend to only use a wah and rarely anything else. So the preamp drive is important to me... but that's just me. Other guys really love this amp more than I do, but I always try and offer a view that is genuine and my own shortcoming through style should not really affect the review. These amps although you might not think so, can be very loud... but in a different way than say that 1959 HW. The best answer as always is to try one if you can, and if you can't always buy from where you can return it!. Thanks for the post and for watching too.

[@peterludlow9847]

Hi Tony hope you are well. I know u did this review about a year ago but its on my list to buy and would be grateful for some advice. I only play at home in a small room and can the di of the amp plug straight into a interface or do you need a load box. Also when using di out does it have speaker emulation and if so can you turn it off. I have a tc electronic impulse IR loader pedal and like to use my own IR. Also looking at the laney L5 studio head, just trying to work out which would be best suited for my needs and nice cleans. Many thanks Peter

[@tonymckenzieofficial]

I still have this amp and I always use a mic for recording in the studio here (gets a good sound), but I believe the di out does emulate a speaker output for recording. The DI out there is no on or off for the emulator... obviously a load box could remedy that - So I think you are spot on and answered your own question. :) Look at this Laney... kzbin.info/www/bejne/oZCTiYeMfN55pqs and a very nice amp for recording etc. and has all those nice things... check it.

You too! Trust you're OK... and thanks for watching.

[@pitpuz]

Many thanks Tony, excellent video!! Can you refer to the DI output in the amplifier? It seems that there is not much explanation and videos about it and how it sounds... Is it recommended to connect it (in terms of sound) to the console during a performance? How much is the sound damaged (if at all) in this case? what do you think? Even electrically - from which part of the board does this port come out? I would appreciate it if you could address this.

[@tonymckenzieofficial]

There is a video on YT here: kzbin.info/www/bejne/l5XSpHWgpbSJZs0si=Zpg2MUuCAvFNucxn that compares the DI out and other stuff on a Marshall SV20 - those DI outs I believe are common and the same basically. Video was by @toneattic I believe... good question and thanks for watching.

[@GuvnaOnSpotify]

Keep going Tony - you are the only guy on this platform that does reviews like they should be done. They should put your archive links on a Wikipedia page, right next to Johan Segeborn

[@tonymckenzieofficial]

When you speak of Johan... you're talking of gods! He is a really great presenter - I have watched him for many years off and on... but I'm not really like him, in my humble view. But very kind of you to surmise that... always remember, if you're looking for me, it's down here :). Thanks for watching and have a great new year.

[@russiancrowe13]

I enjoy watching your videos. They do show up in my suggested videos since I subscribed to your channel. This is the best video I've found for this amp. I'm really considering buying one after watching your video.

[@tonymckenzieofficial]

Great to know that it has helped. It's why I make them. Thanks for the sub and for watching.

[@guitardave]

I’d love to see you do a review of the Soldano SLO-30. Not cheap, but a really great amp - would be interesting to hear your take on it.

[@tonymckenzieofficial]

I don't have one :( but I did review a Mezzabarba M-Zero 1 which is similarly built to a Soldano 100 amp here: kzbin.info/www/bejne/eWW6fZtmq76Uf9U and if you really want to see one of the best amps there is, then watch that video because honestly, its got the lot... but sadly (like most top end stuff) also has the price to match. Piereangelo made that amp for me some while back after discussing with him and my old friend Asim Can Gunduz (Awesome John - check him out) and what a brilliant amp that is. I released that review in June 2018. Check it out and I actually show the playing on there with some other guys I know who I invited along to 'have a go' :). Thanks for watching.

[@vin9976]

Hello there! How do these 20w setups (ST20 and SV20) do for clean headroom? Like not super clean but like ACDC Rhythm/Malcolm style stuff? Wonder if they cut it or if they don't have enough of a sizeable transformer for it?

[@tonymckenzieofficial]

They tend to sound very good to me. Obviously cranked there is far less 'clean' but the series tends to be quite flexible... thanks.

[@andrewfountain7566]

Hi, this was the review I was looking for!!! I wanted to know about the quality of design and build because Made in Britain (England) always meant something but it seems now to get blurred. Keep up the reviews, I’m now a subscriber and represent the generation that know if you can’t say some nice or constructive then …….

[@tonymckenzieofficial]

Yes I get that. This amp is pretty cool really and certainly does sound the part... It's 'made in the UK too' and like you, I know that means different things to different people, but as I understand it (after visiting the factory recently) this amp really IS made in the UK. Thanks for watching and that sub... appreciated.

[@therealrem]

Great review Tony… as always 👍

[@tonymckenzieofficial]

Glad you enjoyed it and thanks for watching.

[@ADIKT_TV]

Hi Tony. Nice review. Just one question, can't decide between Marshall 2525h jubilee or this JTM ST20 for using at home. Which You would choose? Thanks

[@tonymckenzieofficial]

The Jubilee 2525 I also have. Its a a very different beast. If you need real drive get the 2525H - works great for rock etc. The ST20 JTM is far more reserved. You would use a pedal for rockier stuff, but for a pedal platform the JTM would be better choice I think. Both nice amps - and check them all in the range - I like the JCM800 stealth I reviewed also. And don't forget the ST20 Vintage either! all great choices but created for (IMO) rather specific styles of music. Thanks for watching.

[@timaddison707]

Great detailed review Tony

[@tonymckenzieofficial]

I tried hard to show this amp as it really is - and it's not a sales video. Hopefully guys will learn more about the amp from this video and make up their own mind from a better informed decision. Thanks for watching and have a great new year.

[@lewismcnicholas2631]

Cracking Review! Great to get your insights Tony - please don't stop! It would be really interesting if you did a breakdown of the cabinets as well as the heads as it seems like great value based on your feedback.

[@tonymckenzieofficial]

I did one of the cabs (shown in the vid) but generally I have loads of 1960a cabs of differing ages and don't really 'need' them. That's generally the reason for it. But if something special came along I would consider it for sure. Thanks for watching... appreciated.

[@alfienoakes290]

Hi Tony, Just found your channel, the best review of this amp I've found yet, no bulls**t and down to earth. What the people need, thank you! Don't let the morons grind you down, keep up the good work. Thanks again ✌

It's great that you used an Ibanez RG type guitar. Most other vids only use strats LPs and SGs. Thank you for this. I'm getting a combo version in trade for my 65 DRRI today. I'm more of a Marshall guy.

[@tonymckenzieofficial]

Great that it helps you a little - and thanks for watching.

[@StratsRUs]

Great Review.Always look forward to your vids. Marshall would be well happy having passed your scrutiny.Well done. I like Fair Deal too.Good people there. Thank you and those guitar tones show the amp off perfectly.

[@tonymckenzieofficial]

Thanks for watching. Yes I like Fair Deal Music - and they are really good on Marshall gear. I always go there myself... and I met Gary a very long time ago at Musical Exchanges in Birmingham (about 1996). Gary is a credit to wherever he works too. On the tones - some guys accuse me of 'you can't play' (ho ho ho - I sure can) and all that stuff but just playing the music alone does not really show those tones for this amp. I could have cranked and played metal on the amp but not the best answer. The last track was cut through a 'copyright' claim from someone that certainly was not Gary Moore... and that had some rock chords in there that might have well also shown the tones of the amp for that situation (think Thin Lizzy) but I cut it because to be honest I did not believe the complainant really. Oh well. Thanks for watching.

Great review. I plan on using amp in my flat. Lounge 4 meters by 4 meters. Which cabinet would you recommend for it? Standard one that it comes with? I see you have hand-wired 1960 one etc. Easy to purchase 1960 hard-wired cabinet for it? Thanks

[@tonymckenzieofficial]

Personally I have many 1960a cabs. But for this amp at the time I used the 1x12 that was designed for the Studio JCM800 Black amp I have... it worked well. Used a Vee speaker in it. Thanks.

[@babetopaz]

great reviews, keep on keeping on.

[@tonymckenzieofficial]

Much appreciated! and thanks for watching.

[@MarshallAmpMan]

Excellent review. Can you do one on the combo version? What do you think of that one? Could you also do a review on the BlackStar St. James amp?

[@tonymckenzieofficial]

Sorry I don't own the combo! And neither do I own a Black star, but in the case of the Black star those are not for me... I have seen with others and prefer the Marshall amps. Thanks for watching appreciated.

[@97guitarzan]

Love your reviews Tony!

Well thanks - and really... thanks for watching.

[@AndrewSnowden007]

112 cabinet or 212 better for small room. Guesses 212 sounds better? Thanks

[@tonymckenzieofficial]

Honestly, you should try both. Its also relative to the room really and the style you play might suit one cab against the other IMO. If you can then check both... and choose speakers with care.... thanks for watching.

[@AndrewSnowden007]

@@tonymckenzieofficial review of amp said 5 watt setting is very loud for a small room. Do you sell cabinets hard wired? Do you recommend a hand wired cabinet? Thanks

[@FormerlyknownasT]

Hey Tony .. could you tell me what make the input / output jacks are please & are the samwha capacitors a good brand ? i think they could have tidied up the silicone around capacitors .. would that cause any problems in the future ? i haven't a clue about this stuff , just picking bits up from listening to ye guys on the tube - thanks Tony

[@tonymckenzieofficial]

Not sure of the I/O jacks are (I might take another look), but the samwha capacitors I have not really seen any problems (or heard of them either no matter what 'some' of those sometimes biased tech repairers might otherwise say. Re quality and longevity my opinion is that if someone can show a pile of replaced ones (they can't) then the caps would not be great, but in the samwha case I don't see any of that. As far as capacitors (electrolytic in particular) all electrolytic capacitors fade over time... whatever the brand in my opinion, so my guess is that whatever brand maybe in 10 or 20 or 30 years or more there would always be problems with electrolytic capacitors irrespective of the brand. Some of those tech type guys have favorites' of course, but do they 'really' last any longer? maybe or not. Great question and thanks for watching.

[@marvelharris9540]

good review... hey Tony what is "evil owl" studios and the significance of the pentagram?

[@tonymckenzieofficial]

I have said this times before to others. Not what you might think. Heres the story (its true!): I wanted a 'private plate for my car... so I went to the government site and looked until I could read something - anything! It turned out to be 'EV11 OWL' :) for just £270.00 so I bought it. The studio used to be named 'Big Dan Studios' which has connotations if you are USA based in slang, so I changed it to Evil Owl Studios' simply because I have the number plate :) - The Owl, I bought and the inclusions you see came with it - which the maker called it an 'evil owl' and I guess with that it would be. So nothing like what people sometimes think... in reality it's just a marketing thing for my studio and the car has it emblazoned... I have a funny sense of humour, but you can find that car anywhere when you lose it, the plate sticks out incredibly well. Thanks.

[@twlowe19]

nice and detailed as expected, great! I recently got the studio Sc20c and once the speaker decided to break in, the thing is fantastic! Shockingly diverse set of sounds for a single channel amp. This one really has me curious as well, be it the head or the combo. Really like to hear the difference between it and the 20w plexi guy in person, which I tried but kind of preferred the 800 studio.. but that was then, ha!

[@tonymckenzieofficial]

I think each has a place really. I have three models of Studio and all great + this one. I think it all comes down to the style you play and then choose best suited for those needs. Tanks for watching.

Its annoying how KZbin changed things from being able to rely on your "home screen" to see new content from your subscriptions to needing to actively check for a "red dot" on the list down the left. I've made the "transition" hur hur and it seems to be working for me. I just got in to the habit of checking the list for dots before I started going down rabbit holes via the home screen. Anyway! Great review as ever sir. I saw another review of this amp where it was compared side by side with the JCM 800 studio and it appears they are using the same iron.

[@tonymckenzieofficial]

Thanks for the info about that. All the Studio series seem to be very sort of similar and I'm not surprised but I did not check so great info from your post... and thanks for watching.

[@polrequena1467]

Amazing. What about compared to the PRS HDRX 20, have you tried one? which do you think its better? Thank you so much, you work is priceless!

[@tonymckenzieofficial]

Thanks. I remain unconvinced that PRS knows more about Hendrix than Marshall... just a personal view and PRS seem to 'muzzle in' to other brands territory somewhat (like the strat). I might lok at one but I'm not entirely convinced about Paul Smith trying to promote this as the Hendrix answer... it just does not really fit, except as sort of 'jumping on the gravy train' I think. Thanks for watching.

[@benitosolomita]

Hello this jewel is fantastic .... I bought one last week .... The sound is beautiful .... But the presence knob makes a bit of a noise like a breath .... Yours has this too problem?

[@tonymckenzieofficial]

I did not notice it myself? But I have to say that often when I have it set it will sit there usually for a while, as all the other knobs do too :). It does have a great sound I agree. Some want to knock the amp in some way, but to be honest this ST20H I think is one of the best in the series, IMO followed by the JCM800 20w. Thanks for the info and I'll look again and thanks for watching.

[@SirLoinMagroin]

That Strat neck pickup really took a shine to that amp. I want one but new they are $1750 dollars in the US. I can get a new DSL100 head and 4x12 cab for the same price. However, all the other 20watt Marshall heads are made outside the UK. Go figure. I assumed mainly because the ST20 is made in the UK and the DSL100 is made in Vietnam but that does not jive since all the 20watt Marshall heads are priced at $1750 dollars here. No matter from where they come from. Great job as always Tony.

[@tonymckenzieofficial]

Oh I know they are crazy expensive in the USA and that's a pity. On the Studio heads I have only ever seen UK made heads? The DSL 100 used to be made in the UK (I had one years back - in green covering!) but later moved to Vietnam as you say. Check those Studio heads again (I have not checked any combos) - you can check my reviews - all the ones I have are UK made... but would be interesting to get a picture of the Studios made not in the UK? Thanks for that info and I'll be in the USA again at some stage and look also... great info. Thanks for watching.

[@jjjddd231]

I'm considering this amplifier and the review was very helpful. As I have never bought a Marshall head before, can I ask does it come with a speaker cable to attach the head to a speaker cabinet?

[@tonymckenzieofficial]

Indeed it does come with a speaker cable and a mains lead, and that important 3 year warranty :). Thanks.

Thanks so much brother, for making this very interesting and highly informative video. I own two Marshall Studio Series 20 watt tube ampheads that I love. 1 SV 20 mini 1959SLP, and 1 Mini Silver Jubilee. Plexi Amps and Modded Plexi Amps have always been my favorite amps to play on. I've always had the opinion that both Plexi and Modded Plexi Amps sound the absolute best when played through Celestion UK Made Greenbacks. The Greenbacks compliment those 2 amps so well . They are my alltime favorite speakers, be they in a 2x12, 4x12, or Full Stack, in the event that a person might want to do some enjoyable house demolition, ripping neighbirhood houses, off their foundations! 😂😮😊, particularly when playing Plexi and/or Modded Plexi. My favorite speaker combination, in a 4x12 closed back cabinet is 2 UK Made Greenbacks on Top, and 2 Vintage 30's on the bottom. I'm glad that I just discovered and subscribed to your channel on You Tube. Greetings and Much Love and Respect From Sonny, in New Orleans, La. PS. Do you live in England. Thanks Again for this awesome video.

[@tonymckenzieofficial]

Ha I DO live in England. I have used Marshalls since 1971. And I have bought/used most including all those you mention. Presently I'm going to show a JVM410HJS (Satch head) which is also very interesting. On cabs I just stick with 1960a, and the old 100w head (hand wired they said) and a vintage modern cab too. Those all cover the 30s, 70/75w and other speakers - I have about 6 Marshall cabs and those are used for all my amps (about 20 inc Marshall, Diezel, Mesa, EVH and many more) and I find those all brilliant speakers... yes they are all Celestions and as I have owned them for years will all be UK made... Thanks for the sub and check my videos - I have LOADS on inside and out amp reviews... rather like this review. I really appreciate you taking the time to post too... and thanks for watching...

Hello from New York!! Excellent review I trust your opinion!! I own the previous 3 studio heads, and am currently thinking about the jtm 30 watt reissue or the studio!!!! The studio obviously doesn’t have the rectifier tube ,do you think they sound very different ??????

[@tonymckenzieofficial]

There will be a difference of rectifier against no rectifier... but I have to say that this amp does indeed sound very good. Check that Marshall playing video on their site and you'll hear it with many tones. Ha I have all the Studio series too... great amps really. Thanks for watching.

Hi Tony, I haven’t seen one of your videos in some time now but it’s nice to see you back. I enjoy your videos, I’m on an amp kick myself here and I actually just purchased a Friedman Dirty Shirley and I do love the tone I’m getting out of this, especially with the Ox and it’s cabinet app I’ve also been using too. Now you’ve got me considering this Marshall head too…… LOL! 🤣

[@tonymckenzieofficial]

Sadly... I have been making videos but for amps there are far less out there that are new... even this one in some while. Some tell me that they don't get the notifications either like you mention. It can be frustrating when to create the videos costs me much time and effort really. I reported to YT but never really got any sensible solution from them. I guess my little contribution is too small for them to bother? But in any case, great to see you. I did try the Friedman but that sadly went back and I don't really trust buying amps at twice the price of this one after my experience with them sadly. I'm sure they do make some great amps, but I doubt I'll ever go back and try another. Thanks for watching.
