Thoughts on Vintage Marshall Bass Amps?

Postby krall on Sun Jan 25, 2009 3:01 am

Anybody ever use any of these models mentioned here? Can these model 1986 50 watters handle a loud band situation? 50 watts doesn't seem loud for a bass amp, although Marshalls are very well known for being loud amps..Are the older four holers considered better than the JCM 800 era two holers?

-1986 JMP Bass, 50W head (four hole inputs)
-1992 JMP Super Bass, 100W head (four hole inputs)
-1986 JCM800 Bass, 50W head (two hole inputs) ( has a mid sweep and a slope control not found on the older JMP model)
-1992 JCM800 Bass, 100W head (two hole inputs)( has a mid sweep and a slope control not found on the older JMP model)

No info on the Marshalls, but I can tell you this:

My main amp used to be a 2xEL34 '65 Vox AC50. 50Watts. It is more than loud enough for me. I used it for years with my not that loud playing indie band. Loud enough for most smaller venues and I even used it without mics or DI, while the guitar amps were mic'ed. In larger venues I used a DI or mic and I never turned the amp up.

No I also have a garage band, which rehearses at very high volumes. My 100W Hiwatt (4xEL34) is more than loud enough and my 200W Hiwatt is the bomb. Lot's of headroom left.

So my opinion is that 50W is enough for most bands. If you play very loud rock, go for 100W or more.

I have both 1970s 1986 and 1992 amps, and I've used the 1986 head through a 4x12 and a 2x15 in band situations. It's loud enough, but you'll get some pretty good levels of distortion. If you're looking for clean headroom, you'd be better off going with a Super Bass (1992). The SB will have some hair on it too, but you'll be able to crank it up a fair bit more before it becomes really distorted, and if you run it with KT88s, you'll have even more clean headroom with a tightened up bottom end.

The above assumes you're playing bass. For guitar, the 1986 is PLENTY loud, and the Super Basses just crush, hehehehe...

Cheers!

To add to my above post: I prefer the JMP 1986/1992 models to the JCM800 versions. They redesigned the circuit in the JCM800 series and it changed the tone and characteristics of the amps. Whereas the pre-JCM800 circuit was not far removed from the late 60s "plexi" circuit.

Don't omit the model no. 1978 Marshall Major 200W head. Killer bass amp! I like to run mine thru an old 2x15" cab.

No doubt! :mrgreen:

But, I have no experience with those, so I can only comment on the 50 and 100 watters. I'd love to have a Bass Major!!

One other thing I forgot to mention about the Major is that they're generally quite a bit cheaper to buy than a 50W or 100W amp, so that's another plus.

Really? But where do you find them? Every now and then I'll see a Major on fleabay, but it's usually messed up, and I don't think I've ever seen a bass version on there. And the amount they got were near late-70s Super Lead/Bass prices. I'd really love to get one of them in good working condition. :D

Well yeah, that's the thing, they are a lot harder to find since they were produced in much smaller numbers than the 50 & 100W amps. But they do pop up once in a while, and generally for less than a Super Bass of the same vintage. Ya can't really compare Major prices to LATE-70's SB's. Plexi Majors especially sell for much less than a Plexi 100W. And it's no biggie if it's not a Bass version, you only need to change about 5 parts to convert it.

Cool. I'll keep an eye out, and if the right deal presents itself, go for it.

Not a Marshall,but close enough. It's an old 70s German Maquis GV 150 (Guitarren Verstarker)
It was one of those rare times when I didn't look under the hood.I saw 4x el34's and ran with it for about 200 bucks. Got it in N. Germany ,so when I got it back to the mountain in Switzerland and started openin thing up,what do I find? A solid state preamp.....They offered to take it back but it would be awhile before I could get back that way ....
....So I decided to make a Bassman preamp to go in there. It took me a couple of trips to and fro ,across the pond ,to get it done ,but I finally did.
The old preamp had a sheet metal cowling that was the perfect place to mount a can and some tube sockets.I took that and a terminal board I bought in Switzerland ,back to the USA and drilled the cowling & made the preamp there

As fate would have it , a couple of '85 JCM 4x12 bass cabs fell in my lap as I was just about to finish the head. I got the top cab for 100 bucks and the bottom for about 400
Ended up with 4x 6550 in the because I have lots of 'em, a 12at7 in the PI to clean it up just a bit and I probably tweaked the V1 cathode values a little just to clean it up as well
It came out soundin pretty good ,like the early 70s rock we all know & love ,when Bass was BASS
I used to see good deals on majors in the USA ,but I really wanted one for my Euro-rig
