This is the five watt world short history of the Marshall JTM45. Amp histories are very hard to make because some folks would rather it be very technical, about circuits and tubes where others just want a run down of all the great players that used them. I try to walk a line somewhere between which is where my own interest lies. Please add what you wished I'd covered in the comments for everyone to enjoy.
Jeff McErlain has become a good friend and collaborator. Players of all levels can learn a lot from Jeff. Here's the link to his website:

[@yetanotherbassdude]

The thing that always strikes me whenever I hear about the early history of British rock is just how *small* the scene was until the late 60s when it exploded. It was literally just a few dozen guys playing in bands in West London and hanging out in Jim Marshall's shop who all knew each other and were all creating something truly unique between them. Makes you wonder if there's another scene like that somewhere in the world today that's winding up to take the music world by storm with something new.

[@gman2380]

Sadly I doubt that man. It seems these days only corporate sponsored dogshit gets any airtime 😠

[@Wardell43]

Sure, I live roughly 20 miles from Mojotone in Burgaw, NC that built the Lerxst for Alex Lifeson, as well as their own line of Mojotone amps and of course Marshall and Fender Clone kits that you can build or have someone build for you. Also Ed Quidley that built Quidley amps and the 7 Sins series is in our neighborhood. The Wilmington Area is a Tourist/College/Retirement Area that has a lot of places to play on every level and so we have a large Music Community. We are not California, Home of Fender, Soldano and Mesa, but you can see musicians from all over the world jamming in the Wilmington Area. Not bad for a town this size. Previously, I've owned a Marshall Super Lead Stack(I bought new from Al Nalli Music in 1972), JTM 602 Combo, and a Marshall JCM 900 50 watt SLX and many other amps Currently I'm using a Marshall JCM 900 50 watt 2500, Laney GH50L and a Laney VC 50 Combo We also have several Recording Studios. I used Low Tide for my Demo, and Cape Fear, Hourglass, Karen Kane and a few others that are professional studios and of course Screen Gems Movie studio and sound stage. So as I mentioned "Al Nalli", I was from Southern Michigan and the Ann Arbor/Detroit thing is what we all grew up on. and Long before Seattle gave us Grunge, It gave us Heart, Hendrix, The Kingsmen, Paul Revere and the Raiders and Sunn amplifiers So there are pockets that have their day, then poof! In my area, there is an amp builder that just put out a notice that he needs a backer so Mojotone will have some Competition.

Agree with your 'decision fatigue' intro... a Strat, a Tele and a Les Paul covers 90% of guitar tones, and a Deluxe, an AC-30 and a JTM45 deals with most of the amps.

[@its_ya_boi_thurston]

My favorite five watt world vid yet! I knew all of this history and trivia but have never seen it presented so concisely and professionally! This channel remains an absolute gem for guitarists everywhere. And I could argue that any decent fan of American music and manufacturing history would get a lot out of this channel too. Cheers from St. Louis! And I second the commenter about the JCM800. I have a vintage '87 2210 for your reviewing pleasure as well!

[@raymondlugo9960]

I just bought a JCM 900 SL-X 50 watt. It seems really cool so far. I also have a 2203, 900 DR, and 2000 TSL. I love them.

[@vladzubac5360]

I have the Studio VIntage 20W head.....it is the real deal (I mean the tone...to have a real deal..you'll have to get an original old Marshall), but it does what it is supposed to. Marshall Origin...not quite in the same league as the Studio VIntage head 20W..but all in all...Thank God that Marshall Exists! amazing video, very informative and super cool narration.

[@WillyPDX94]

"Decision fatigue". What a great term and you are absolutely right. It's the reason I don't have a single modeling amp. I bought one a few years ago thinking it would be good to have so many amp and pedal sounds in one box. But I ended up hating it for exactly the reason you suggested. Too many choices, plus the feeling that you were "wasting" the amp if you only used one or two favorite settings out of the thousands available. Never again will I buy this kind of amp. I'm thinking about buying a Fender Deluxe Tone Master. What I love about the amp is that they focused on one classic tone, didn't add a bunch of features or controls, and got somewhere in the ballpark of the Deluxe sound. And it's so light in weight. Haven't pulled the trigger yet (because I don't really need another amp) but it's appealing.

[@stratcat4450]

I still can't warm up to any non tube amp, but in the end it's all in your fingers.

[@WillyPDX94]

@@stratcat4450 Yes, I agree. Solid state amps can be quite musical, and a few of the high end modeling amps can replicate tube tone so well, I don't think I could tell them apart in a blind test. But a really good tube amp has its own spirit and behavior. It's not 1 + 1 = 2. A solid state amp is like that solid girlfriend who is reliable, predictable, and fun to be with. The tube amp, on the other hand, is like that weird girl who doesn't seem that into you, but if you play your cards right, will take you places you've never been.

[@tylerangle1990]

This is my stance on it too. For a long time I didn't understand the appeal of a single channel tube amp until I started using them. Then I just stopped worrying about switching sounds or flipping effects or whatever, just plug it in and go. You get a decent sound within a few minutes and then call it a day. Now I don't like Kemper or Line 6 etc. at all. Constantly tweaking settings to get a sound I can get by just turning on a Twin Reverb, AC30, or JTM45 doesn't seem like any fun to me. I want to play guitar, not program a computer.

[@PapaWheelie1]

I would gladly exchange thousands of modeling tones for one great tone. Seems like all I do when I plug into one of those things is turn knobs not play

[@johnmarshall3903]

I've got real vintage Marshalls, why would I ever waste time with a modeling amp?

[@jfrockon]

Just 30 minutes? One of the best Marshall "history" videos ever. Very nice man. Diggin your page. I plugged into a Marshall for the first time in the summer of 1976. I was working part time at the local music store in Muncie, IN. We only saw that one Marshall the time I worked there. I was scared of the volume, but turned it up and hit the opening chords of "Communication Breakdown" Holy shit! It would be a few years before I finally got a Marshall combo, it's been Marshall since. I got a JVM series now days.

[@willmyers6537]

I've got to take some exception to your advice to Line 6. What makes the Helix a really interesting piece of gear are the custom amps like the Cartographer (Ben Adrian's highly customized Traynor), the 'officially modeled' Revv amps, and the 'official' Grammatico La Grange. The classics are great, but I love it when a classic is tweaked by the obsessed tone chaser.

Great video. Mid 90's I stopped at a pawn shop before work and a Marshall plexi head that read JTM45. I knew what a plexi was but never heard of this model before. I was about 18 at the time and living with my girlfriend so money was extremely tight. I wanted to buy it more than anything but I knew the price tag would be $1K or more. It was $330, my heart actually jumped. "They miss priced it? I gotta get this fast." The very next day I walked out of a pawn shop with a mint JTM45 and payed $321 tax and all. Eventually years later traded it for a bigger Marshall but I do regret letting her go. So much tone with so many options, clean or dirty, I highly recommend getting one or trying one out.

[@jonathanduffett8374]

My band mate had a coffin logo JTM 45 and an open back Marshall 4*12. We used to crank it in his cottage. We didn’t appreciate what he had at the time. Mike Doyle came over to the UK to see it and negotiated the sale back to Jim Marshall. A reissue copy of that amp was done. Turns out it was one of the very first Marshall amps and likely the first 4*12 cabinet built. It’s in the Marshall museum now.. I now have a 1965 Plexi JTM 45 (ex Martin Barre) and it is a beast! It does not exhaust the full range of British amp sounds though. Vox ,Selmer, Hiwatt, Watkins, Laney......

[@TheRMBoyd]

The Dave Davies anecdote about slitting the speaker and inventing fuzztone in 1964 is one of the same stories told about Marty Robbins studio lead player on "Don't Worry 'Bout Me" released in 1961. Other similar stories about those days include rough handling of an amp causing breakage or loss of one of the power tubes- but the session must go on, and they hated, but later loved the sound ... I've heard these stories for as long as I've been playing out {1968}, just attributed to different songs and artists. The latest version of the story I've heard was studio ace Grady Martin playing a Fender Bass VI through a "faulty" mixing board?!? If you've ever tried any of these methods, razoring a speaker cone would actually seem to be the least effective- although upon relistening to "You Really Got Me" on some quality headphones, I DO hear something rattling! Well, at the very least, you are carrying on the honorable tradition of passing down an urban legend that this old Bluesman has heard from many sources, and attributed to many players, many times before! Rock on!

Probably like you I have Fender, Vox, Marshall amps and before in 70s I had Selmer rather than Fender a better amp, Carlsbro more reliable than Marshall and Peavey better overdrive than the Vox. However, the marketing was better by the former. I now use Fractal Audio Axe fx III with Fender Bandmaster, Mesa2c and Matchless Chieftain and Dumble ODS. My go to amp is Boss Katana. Only the over 40s and old folk like these amps. Today youngsters use multifx through frfr. So altho it is historically good. The J45 is good but has been overtaken just like Gibson and Fender guitars. Kiesel, Strandberg, Waghorn all better built and more playable. I am 71 and we should applaud the past and also move on to today’s greats.

This is great history. I love these kind of videos. I'd love to see a Mesa/Boogie one some day.

[@fivewattworld]

It’s on the list.

Thanks Keith, this was very informative! I have recently become (talked myself into) interested in a Marshall head... I have one of the limited edition (navy blue) 20w Studios in the Vintage 1959SL variety on the way in November. Of course, with no master volume now I am in the market for an attenuator, ugh. The rabbit holes we go down! I love the intro... yea Jeff! I am proud to call myself one of Jeff's students.

When I was 15 I told my dad I wanted a 100 Marshall and after saving up the money I almost bought one. One of my dads guitar player friends heard this and told to get something more practical. I ended up getting a Vox AC-30.

Keith, you should do a story on the Highly Prized, One of a Kind, and Rare Marshall 4001 Studio 15 Amplifier. They are fabulous all-around amps with some very unique circuitry - for example, two bias pots that allows one to bias each 6v6 power tube separately so you can match any tubes you have, BRILLIANT! No need to buy a matched set - (I'm told - the only amp Marshall ever made featuring 6V6 power tubes/valves). It is a Legend in it's own right as you should know, as well. A secret weapon used by many pro's to record award winning albums in the studio and to perform with live on stage. This amp, I believe, showed us Marshall was light years ahead in thinking, regarding the boutique amp market, back then. They are a 'Swiss Army Knife' Amp in the Studio, to be sure! I still own and use two of the 'only 500 made' and I still use them on numerous studio and live projects along with my stable of Tweed, Brown & Black Faced Fenders & THDs. Keep Up The Fine Work, And Stay Healthy & Safe! Always Great To See What You Have For Us, My Friend!

Great Marshall history Keith, and excellent research behind it as usual! Thanks.

Thanks Joe

I live in Hanwell and build tube amps for fun, including a clone of the JTM45 - the first proper production Marshall amp Jim sold from the building that is a few hundred yards from my house.

[@robertamato358]

Another great episode! Thanks.

Strymon nailed the three amps you described in the Iridium. I have 2 glorious Carr amps that I LOVE... a Mercury V and a Skylark. But, the iridium is such a great practicing and recording tool.

[@wrencormier513]

I love the bass in this intro

[@stephenhammonds2834]

I bought a master v (year unknown) in 1986. It always had something wrong with it, and I learned how to work on tube gear on that turd. But when it was sorted, and turned up to ten, it was glorious. And painfully loud.

Great Short History! Keep them coming!

[@jimmymurphy7789]

What a great video this is - Thank You so much.

[@jasong546]

Excellent job, and really enjoyed learning a few things Keith thanks!

[@fivewattworld]

Thanks for watching Jason.

Funny how Leo copied the "standby" switch from high-voltage amplifiers, unaware that it was as useless for low-voltage receiver tubes (found in guitar amps) as the "polarity" switch was for three-prong early Marshall amps. And we keep those standby switches to this day, because all amps are effectively copies of early Fenders!

[@johnsalaman503]

Thank you so much for this ..was extremely exciting to view, as well as informative..great job..rock on...

[@garrettboomerbender]

Great video as always! The only thing I would argue about those three amps is that they don't cover modern high gain tones 😝. As a somewhat young guitarist (19 about to be 20) I would love to see the history behind the 6505 or 5150. All that being said you can cover pretty much any tone under the sun with those three amps that you mentioned.

[@RootRoad]

Awesome video! Always look forward to your submissions!

[@TheAdjacents-ABQ]

Brilliant piece of work here.

[@wildwindguitars]

As always, excellent beyond measure.

[@OkSharkey]

I did not expect to see John Inman in a five watt world video :)
