I mean, someone correct me if I am wrong, but Angus still drags his old JTM45 around for playing live and it was one of his main studio amps as well.

o yeah well i've always liked the beefy crunch of the plexi RI. IMO the jtm has a slightly thinner sound (as you can tell by most ACDC recordings, very bright but lacking fullness). my favourite marshall amp is the jcm800, but if i had to pick a second it would be the 1987.

really? I have the exact opposite feeling about the two.

JTM45 is fat and bluesy and the 1987 is bright and aggressive. Definitely in no way is the 45 thinner. If anything the 1987 lacks fullness in comparison. But again, that's just my opinion. I personally found it too bright and ear piercing for my taste, as well as being noticeably louder than the 45, which is really what kind of pushed me towards the '45.

My amp has gone everywhere from '65 JTM45 spec to '67 JTM50 (which is really equivalent to a 1986) and that is how I've felt about the two. The JTM45 had a ton more growl.

To the TS: if you really want a good comparison between the two amps with the same player playing them, check out Greg Germino's website.

http://www.germinoamps.com/audio/classic45/061307_5.mp3 (this is the one you really want to hear of the JTM45, listen to that lead tone, perfection)
http://www.germinoamps.com/audio/lead55/Custard%20Pie.mp3 (1986/87)

Here is how I'd characterize the JTM45. It's like a much more refined sounding tweed Bassman. Generally, I wouldn't use Angus's tone to classify the tone of the amp because I think his sound lacks character (just my opinion). Instead, this is the clip that always reminds me of what the JTM45 sounds like.

Listen to the lead track (I think it probably starts at about 0:30 or so), that gives you that thick, fat and musical lead tone, of course Eric Clapton's '60 les paul probably as a ton to do with it too...

JTM45 is hardly quiet. The 1987 is just loud as fuc k. It's louder than any 50 watt amp I've ever played and is bright enough to make your ears bleed. A JTM45 will leave your ears ringing, and will probably be too much for most gigs when cranked full out but at the same time, I find it a... "loud but reasonable" amp. It sits nicely in a mix if you have a loud drummer. But otherwise might be too loud. A 1987 though will drown out the rest of the band. A lot of it depends on the speakers. A quad of 20 watt greenbacks are loud with my JTM45, but a quad of G12H30s is ****ing loud with my JTM45.

I'll give you a word of advice, pass on the Marshall reissues. They are cheaply made using cheap parts, cheap transformers and have no business costing as much as they do. Imo the three best JTM45 amps on the market are made by Metropoulos, Germino and Blockhead. They're more expensive and if you can't swing one of those, there are a lot of other makers out there who do great JTM45s as well. They're simple circuits, a lot of people build them well. Ceriatone is probably the cheapest option, but even that is better than the Marshall reissues. The transformers that Nik uses are made in Malaysia but they're not any worse than the pieces of shit that Marshall puts in theirs, plus the Ceriatones are actually handwired.

More JTM45 ear candy...

http://www.youtube.com/watch?v=kUt3hFnbRBo (this is personally my favorite, even with that shitty recording and is the best demonstration of what a typical JTM45 sounds like)

JTM45s are my favorite amps ever, they have so much character and are so unique sounding as really just that bridge between a vintage Fender tweed and full out Marshall, really takes the best qualities of both. But I'm curious as to what kind of music you're playing. A JTM45 will cover a lot of ground from country to blues to blues rock and hard rock. But a 1987 will be more aggressive and have a browner sound. Style-wise it might be better for you. Depending on whether or not you'll have a practice space that really lets you rev up the amp, and play loud, you'd probably need an attenuator with either one.

ok cool. i play mostly classic rock like acdc, led zep, the who. the heaviest i'll go is probably early black sabbath and i rarely do that. i was looking at the ceriatones and i hear theyre one of the best. i dont have the budget for a $2000 head like metro amp. i like the sound of the last video with the '59 les paul. i was also thinking of having a master volume installed into the jtm45. will that ruin the tone at all significantly?

Personally, I despise master volumes. I think they ruin amps. But that is my opinion. I had an amp with a master volume and I just turned the master to 10 and used it like it would be without the extra knob,

a MV will change the tone of the amp. You're not going to get that same cranked amp sound as it's a combination of pushing the preamp, the power amp and the speakers.

But there are some good PPI MV circuits out there. If you go to the Metroamp forum, run a search for teh Lar/Mar PPIMV.
#15
ok guys. one more quick question and i think i'm good. will the lar/mar ppimv be able to give me that cranked sound at low volumes? also, is it bypassable if i raise the mv all the way?
#16
Lar/Mar is pretty good. No MV is going to get you the sound of a fully cranked amp at low volumes because a good bit of the cranked amp tone comes from the pushed power section along with the pushed speaker, but keep the MV at... say no lower than 12 o'clock and you probably won't experience that much overall tone loss. Any more than that though, you're going to lose some tone, but that's just the sacrifice that comes with having the amp at low volumes.

The Lar/Mar is the best MV circuit I've heard, there are a few others out there, the Lar/Mar is a variation on the Ken Fischer design, Nik probably already knows it, if not I'm sure he will install it if you show him the circuit. And yes, it is bypassed when you turn it up all the way.
