[@peterharvin2775]

It's got that thing. That Marshall thing. That lip curled sneer and rude gesture attitude. It's a thing of beauty and it's why Marshalls will always be my favorite amps. Great job exploring the possibilities.

[@christianemrys2115]

Had one of these for a couple of years now - still absolutely adore it. Throw an SD-1 in front of it and you have the perfect recipe for great old school metal tones 🤘

[@angusorvid8840]

That's my style! Love boosting old plexis with SD-1s. Best tone in the world.

[@OneHandleToHandleThemAll]

The Marshall SC20H also sounds absolutely killed with SD-1 in front, it's the pedal that just delivers.

[@ahmetayaz41]

Throw od3 and it roars

"Passes the smell test for me" because these EL34s are cooking! Amazing demo and playing Leon, thanks :)

[@LeonTodd]

My pleasure!

[@Taylor___]

Your riff game was on fireeee in this video. So many great songs!

[@andreasjohnson4502]

Great playing and sound, Leon. Very inspiring!

[@brussalis]

Another wonderful run through Leon. Straight in with it from the off. Plenty of tone playing, pup switching, guitar pot control. And your talk throughs are A1. Love what you are achieving with this amp. In fact, everything you demo and try out for us, you make it sound so good even if in conclusion, you end up as not a big fan of something. Testament to your playing. Legend 🤘🤘.

[@leftygtrplr6184]

Michael Schenker and Kings X riffs all in the same sequence = awesome!

[@zundap100]

Great playing and sound. Marshall has done a great job with this amp. Thanks for video.

[@murrayguitarpickups9545]

G'day Leon I was just talking to Alex from Sirius about these, I had my eye on one when he offered me one of his handbuilt masterpices that covers all these tones and then some. I've had it for a week now and its blown my mind!

[@TheToneWork]

Great video as always! It certainly nailed the classic tones.

[@coreyharen24]

Hell yea this sound incredible! Killer playing as always!

[@brandongullion6353]

Got one of these around 2 or 3 years ago and it is such an enjoyable amp to use. Very easy to get lost in this thing for hours lol.

[@renoman_]

Sounds so good !

[@foolishbillyproductions8071]

Another great vid..you have shown how diversified this 20 is ..ripper

[@heavybrett-al4082]

Now that's rock n roll....and I like it👍🤘🎸

[@damianval4626]

Love to see you demo the whole trio of the studio series mate 🙏

[@chadhagene7665]

Theres 4 now in the studio series.

[@GRBAquatics]

Very Cool, Thankyou Leon. Such awesome Sound and playing as always. Hopefully one day. All the Best. Cheers

[@cbiltz75]

Once you Fryette Power Station it things get STUPID GOOD. Its the secret Eddie had. Re amp a pissed of amp. So much control and it IS the TONE!!!

[@anthonymichael3029]

I had the bright cap removed from the high treble channel volume and I found it made the amp much more palatable with plenty of bite still. This amp is incredible

[@amercieca]

Wow!!! You got soooo close to Blackmore tone with little tweaking! Brilliant! Great demo, great playing too! 🎶🎶🎶

[@LeonTodd]

Thanks a lot!

[@void_snw]

Added a switch to choose the bright cap value on mine. Can wholeheartedly recommend that to anyone. Sick amp.

[@Taylor___]

@4:41 A bit of Cupid's Dead, yes mate!!! SO fun to play

[@KirkyDrums]

10:11 ..That's the tone!! I looked away at the dog for 15 seconds and bam sounds great to my ears and Loved the GM faces Leon

[@paulwebendorfer5627]

Great review, man. Would love to see you do the 2525H too, if you could get your hands on one.

[@TheOtherJohnBrowne]

Glorious. Glorious tones all around! Aren't amps the best thing ever? I wish I didn't need food to live so I could afford more amps 😂

[@BigTyronie]

I know a guy who went anorexic to afford a Diezel Herbert in the initial offering. He went from Ramen and Rice chex to no food and a third job. He lost so much weight that his third employer asked him wtf was he into. He thought it was drugs but when he found out he was starving to buy amps he told him to take a pizza everyday. 🤣

[@TheOtherJohnBrowne]

@@BigTyronie That's dedication right there! Your friend is a true inspiration! 😂

[@electronik808]

modified mine i added an internal load and an ir loader pedal is amazing

[@KristianPage]

Great review mate. I just grabbed one.

[@LeonTodd]

Hope you enjoy it!

[@matt926uk1]

I have an sc20h. For a pretty simple amp its quite versatile. I tend to keep the preamp pretty high, otherwise it gets very bright because of the bright cap and then i use my guitars volume if i want a cleaner tone. The low input is great too, works pretty well with a big muff or ds-1. I play, grunge, 80's hair metal, and alternative rock on this amp and its perfect for those styles.

[@tasteofmetal1493]

I love my SV20 stack,Killer amp. I still prefer it over the SC20. The Jubilee studio model is also very good.

[@RG-yz8ov]

I'm really enjoying the sv20h going into an alnico cream, i use a ironman-ii mini attenuator. I had a heritage g12h30 55hz in closed back cab but the cream in an open back 👌

[@LeonTodd]

Very nice!

[@greghitt1704]

Super nice playing Leon as always. These studio amps still pack a punch into a cab. I got mine into a Freyette PS-100 which really helps get it in the sweet spot without angry neighbors. I picked mine up on a trip to Bangkok where you can find some rediculous new amp deals - legit shops with legit amps at real low prices. Love to see you try out the JTM or SC 👍

[@RaiderJay9092]

I'm running the same set up. I've been gigging this amp for 3 years. Fist 2 I ran it with a Weber Mass. Been using the Fryette PS100 since last July. Much better and I use the extra channel on the Fryette as a lead boost.

[@greghitt1704]

The PS-100 plus KHE 8x4 is an amp game changer for me (well for my tone enjoyment). Tom Quayle likens it to an analogue Axe FX.

[@airozo59]

Love mine with the SD-1 or a Freidman BE-OD and running though an Ironman II Mini only because I'm old and my ears ring enough already.

[@gerrydaly5409]

Hi Leon- great tones. I bought the same amp recently 2nd hand. I also just bought a ticket to see AC/DC play in Europe this summer - the concert ticket almost cost as much as the amp 😂

[@user-qt2ok6gd6s]

Got the combo version, swapped out the original speaker for a creamback, its very dynamic just like a higher wattage plexi, my only niggle is it has a 10 inch speaker, other than this its a fab unit.

[@gergelyboros8138]

I love my Sv20, its MV modded "friedmanish" style but pure marshall vibe

[@mrchrisbeaver]

Does the MV Mod sound much different to just putting a volume pedal in the send/return?

[@lameguitarist7264]

Each time you demo a piece of gear that i happen to own, it makes me realize how much my playing sucks 😅

[@ianfurqueron5850]

The last thing I really need is another amp (I have an old JCM800, an Origin 50 as well as a bunch of others), but damn you make this sound good. Definitely tempting if I come across one used locally.

[@Cherry_Sunburst]

EXCELLENT.

[@BobGuido]

This is an awesome amp for use in the studio. It has great edge of breakup tones when you dial the gain back. Almost a little bit of Vox Chime at these lower gain settings.

[@LeonTodd]

Really impressed. Would be fun with some Alnico Blues!

[@BobGuido]

Yea! Very few candidates out there for the "1 Amp" album chameleon, but this head could do a whole record if you had a cab with an Alnico Blue and a G12H/G12M@@LeonTodd

[@tonedowne]

Would love to see you put the head to head with the PRS HDX 20.

[@Gene2713]

AxeFX III Sounds the best overall in my house but amps still feel so good under the fingers!

[@mickbuffalo]

It’s funny when I try a new amp or pedal out whatever brand I try I always end up aiming for a Marshall sound!

[@irishRocker1]

Try the SC20H please! As you have done this demo, it would be a good reference for comparison.

[@MrNeilfatmonkey]

I’ve got this and the SC20H and it’s surprising how similar they are stock. The SC is a little less spikey in the top end, but there’s not a lot in it. I run my SV just how you had it and my SC with the master volume and pre amp gain at about 1.30. I think an SD1 in front of the SC sounds as 80s rock as you can get.

[@Davidlovesmusic311]

Good day Leon. Would u, when u have time do a review on the valeton gp 200? I finally went digital

[@petedambski3792]

I have the combo its absolutely the best sounding amp i have ever owned. I'm selling my 1979 Jmp 50w which i have played and toured with OCDC Acdc tribute for 11 years. yeah really, its that good and i'm getting the head version. Can't touch this amp.

[@LeonTodd]

That's wild!

[@bungwung4797]

omfg its sound killer

[@Smittefar1]

Very cool - I have been toying with the idea of getting one of these - Or maybe, I should get the JTM ST20H instead ... or both. I have already admitted that these early Marshall tones are exactly what makes me tick.

[@LeonTodd]

I think the SC20 is calling me now!

[@pedrolourenco2707]

I was hopping I would finally hear a comparison between 20 and 5 watts power mode, on a decent demo! Also I wanted to hear a volume pedal in the loop, just to hear the preamp section distortion! :/ .... And when you do the SC20H demo don't forget to crank it to 10 and make it sound like a plexi (and a side by side with this one!)

[@spdoi]

It's awesome! Feisty li'l bugger! Mine's modded by Folkesson🤘😎

[@ToneScientist]

I've been GASsing for this little amp for quite a while, but Fractal adding its model a few months ago kinda stopped my GAS, for the moment at least. I guess you'll do a comparison soon between this and the fractal sim, right? 😬

[@timmcvittie436]

Love these amps. Also gratuitous AC/DC. 😎

[@LeonTodd]

The best!

[@pharmerdavid1432]

I'm leaning towards getting a Friedman, because they have master volumes, while the Marshall SV-20 and ST-20 don't, although they the 5 watt triode option. I couldn't decide so I got the little JTM 50th anniversary 1 watter for now, even it can get too loud for home use if not careful. I'll probably go for the ST-20 eventually.

[@gitarbangsatchanel8036]

No one digital stuff marshall like a real amp like this

[@scottpeters4401]

All the Studio series amps are great…I have the Studio Jubilee,and in many ways I prefer it to my 87 100 watt jubilee…The Plexi is great too…Only downside is the prices here in the US,roughly $1800 for one of these…

[@greghitt1704]

Take a holiday in Thailand and while you’re there save yourself $600 US on one of these - CT Music Store in BKK has them for 45,000 THB ($1,250 US)

[@sebastionhawk5565]

2:47 Armed and Ready : MSG!

[@pericopalotes2183]

@8:00 Sin City !! 🤘

[@pete3189]

The head is great - anyone have thoughts on the combo version?

[@MrSpike7590]

Very Cool I see Bogner released a vintage style head called the JB45. There’s a few videos out Michael Nielsen and Blake Mansfield did them

[@TechMetalRules]

Please do a video on the SC (mini JCM 800)!

[@LeonTodd]

Hopefully soon!

[@andrewplant9206]

Dammit, been putting off buying one of these to go with my sc20 but fuck it im gonna do it.

[@dominicgibson9529]

I commented to Michael Nielsen yesterday that these small amps are just getting better.

[@Robstafarian]

I am champing at the bit for a Synergy SYN-20IR, myself.

[@calimusic2007]

Have the baby JCM800 (SC20H), sounds better than JCM800 I had from the 1980's. Better gain stage, and having an fx loop opens up multiple possibilites such as 4 cable method.

[@robertj1303]

See you using your DGT SE. The shop that sold me mine screwed it up by thinking they knew how to do the action>> it starts ok and gets worse until its so far off the fretboard past fret 15 it hurts your fingers. The nut is crap and the pickups are so low I am surprised it does anything. Off to my tech next week with a new nut, locking tuners, Nanoweb strings (PRS strings are horrible). If he cant fix it, its going back to the shop! Very disappointed 2nd PRS SE that is crap! 😅😅. Sorry for the rant, this amp sounds good, how do you rate this with the Marshall studio JTM?

[@franciscofronza6838]

Have you tried the JCM800 studio Leon?? That would be a killer video too man!

[@LeonTodd]

No but I need to now!

[@franciscofronza6838]

Awesome!! If it’s not asking too much, consider doing it with real cabs/ speakers!! Looking forward to it man! Cheers from Brazil!!

[@andrewchow6357]

instead of jumping channels with a patch cable - should also try a y cable

[@EnJoony]

The 20 watt Studio Series amps are some of the best Marshalls EVER! HANDS DOWN! PERIOD! 😀

[@edwardgrassel872]

I think they discontinued this actually. I had an order cancelled on me saying that the manufacture doesnt plan on fulfilling the order.

[@v8makoshark]

Awesome amp indeed and awesome playing, Leon. Have you tried the JTM studio yet ? Marshall should concentrate on making these and not headphones 'n' earbuds etc. Got all the studios, fcuk'ing ace little amps !

[@LeonTodd]

Really keen to try the new Studio JTM. Tempted to nab an SC though :D

[@Justin.87]

I have the SV and matching cab. My mate has the origin. No comparison Vintage made in the UK. Origin made in china?

[@andyblakely7576]

Have one, it’s super loud for a 20w amp! I mean really loud.

[@wildebassman]

How noisy is it at idle? I bought a new Silver jubilee and the PT was noisy in a nasty way even through the speaker.

[@zandig666]

Sweeet !!

[@TheRealJayguar]

I have this in purple with the cab, i had to put an attenuator on it as it is VERY loud for room playing. what speakers are you running this through?

[@LeonTodd]

25w Greenbacks here

[@dive-bomb]

try the jubilee!!

[@martincockburn6821]

Such a little beast hey 😁 you're welcome to grab my 212 vert cab if you want ? It has greenbacks in stead of the vtpes tho. Sounds mint with the Sv and the DSL 20... And the evh 🤘

[@ahmetayaz41]

i boost sv20 with od3 and it sounds greater than sd1

[@MichaelSorensen-bl3ec]

Best amp Marshall put out in years. Been my main amp for a few years.

[@LeonTodd]

I'm pretty impressed! Proper tones hey

[@MichaelSorensen-bl3ec]

@@LeonToddTry it with the Legendary Tones Hot Mod or Mr Scary. Neat little reversible plug in mod that gives you an extra preamp tube. Really ups the ante. Some people complain the the amp is noisy, it does hiss quite a bit when you really push it, but put a noise gate in the loop and it's very quiet.

[@LeonTodd]

@@MichaelSorensen-bl3ec I've got one of those! Must try

[@antonioj2509]

Hi. Congratulations on the channel! I would like to ask you a question if possible. in your opinion and have you been able to try it. Which speaker would go best with a 1x12" screen for the Marshall STUDIO VINTAGE SV20h head, what is the ideal combination and would it make the best match? With : 1° Celestion G12M 65 Creamback 1×12" 2° Celestion Vintage30 1x12" 3° Celestion V type 1x12" 4° Celestion Greenback 1x12" 5° Celestion Classic Lead 80 1x12" With what Ohms would be the ideal or best for the speaker with the Marshall SV20h head? With : 1st Speaker 8 Ohms 2nd Speaker 16 Ohms Thank you very much in advance for the information (if it is possible for you to give me your opinion) and sorry for being so bold with the query, I hope I don't bother you. Thank you very much!!Greetings!

I like 25 watt greenbacks

[@antonioj2509]

@@LeonTodd Thanks very much!!Greetings!

[@jamesnortonofficial1566]

I wonder what that head would sound like in a Vox blues cab

[@Chillnote]

Can anybody recommend an IR or speaker for the SV20H? It always sounds to shrill to me, with too much nasty treble.

[@2550marshall]

York Audio, MRSH 412 M25- "421V-1". For a real cab the Marshall 2061CX is awesome. Marshall should re-release that cab specifically for this head. It looks so much better.

[@Chillnote]

@@2550marshall Thank you so much, I really appreciate it

[@Terry_Aki]

Agree.

[@BigTyronie]

Its funny Leon bc my first actual head was a 1972 marshall super bass 100w. It was just that… turned the mids all the way, treble at 1 oclock bass at 10 and crank it. Loudest freakin thing ive heard ever and since. Ridiculous and it only sounded good cranked. But i still set eqs up like that. And I love the Lionel Richie guitar line

[@pedrolourenco2707]

ok, go film part II!

[@redcomn]

I tested this with prs hdrx20…… It’s harder to tame sv20 then hdrx20 honestly.

[@Paul-D]

I thought the Sv20 was just perfect and then the JTM studio came and blew it away for me haha

[@finishin.my.coffee8780]

I've noticed you've been using that DGT a lot lately. Are those really that good? I keep hearing people say they're great, and every so often someone will review it or I'll see a comment that makes it seem like they're not all they're cracked up to be. Most recently, I saw someone describe them as "Vanilla."

[@LeonTodd]

No guitar is going to keep everyone happy. If you like PRS and you like old Strats and Les Paul's then it's pretty much the best blend of vintage and modern styling and tone out there atm. The core is phenomenal and the SE is very good.

[@Robstafarian]

The PRS SE DGT is worth trying for its neck, which has a unique profile among the SE guitars, if nothing else. Personally, I think it is great for as close as I will get to playing an LP (due to neck geometry).

[@andreasjohnson4502]

Incredible sound you get out of that PRS Se DGT. I have one as well and just too much bass in it for a band situation. I have a Epiphone Les Paul Lazarus (Joe Bonamassa) which is so much better in comparison. But I guess Leon is very good at making a great sound.

[@Robstafarian]

​@@andreasjohnson4502Have you considered modding your SE DGT with a concentric (i.e. stacked) 500kΩ/500kΩ audio pot for the first position to make room for a 1MΩ, reverse-audio bass pot (G&L style)? I plan to keep my electronics mostly stock (replacing the standard pots with duplicates of the stock, push/pull pot for series pair and neck polarity-reversal options) because my SE DGT should be somewhat representative of production for demo purposes.

[@andreasjohnson4502]

No, I haven’t started modding it. The guitar itself is good with the neck and the tremolo. I might sell it as I don't have the skiĺls and knowledge to do the mods you indicate above.

[@anthonyhoffman6052]

bottom end? it does Metallica very poorly. not to mention that Whitesnake riff u played. "All you're lovin tonight"? it farts way too much. thin 80s tones is all u get here.

[@letsgofuckingcrazy]

The way it reacts to pickup, picking attack, volume of the guitar and booster is totally unmatched by another amp. It is "right" from the first chord. it's the tone+fell all the other amps, modelers and pedal wanted to replicate but failed . And you play much better because it reacts to your playing and dynamics.
