I have the opportunity to get my hands on one of these, but I'm not that sure of the actual price range..

how much is today a completely original 1968 JMP50?

sorry, don't have any pics guys..

in the us or canada, if you find one, probably in the thousands. i would think around 5000$ for clean amps.
if you can, grab it. very nice amp.

Double check the year, JMP came out in the mid to late 70's I believe.

Nope. I have a 1969 JMP50 short box head. Last i checked its value it was around the $5k mark.

The '68 JMP 50 watter IMO and that of many others, is the benchmark for Marshall overdriven tones. If it's all original and sounds great at 5K or under, grab it.

"JMP" usually refers to the 2203-2204 master volume amps, which came out in what, '75?

amps made before then, which would all be the 4-input non-master type, would be referred to as a "plexi" or a "metal-front" marshall, depending.

Problem is, people are using the generic terms instead of the actual terms for the amps.

1967 first of the JMP series. This included the 1959 Super lead or Super bass heads, 1987 Lead spec 50 watter, 1986 model bass spec 50 watter.

What most folks think of as "JMP" is the mid 70's with big rocker switch series, most of which are 2204 and 2203 models, but there were some 1959 and 1987 models thereof.

So the OP is correct, a 1968 50 watt JMP can be lead or bass spec 1987 or 1986.

And they say JMP on the front panel:

This is a 68 plexi off Gbase, note the front panel JMP designation.

These are JMP's, your daft saying otherwise, i don't care what you say, hence the "JMP" on the front panel.:sarcasm

You just love showing those off! Stop it!!


I had to build me a JTM 50 from a Metro kit. I also have a tube rectified YBA-1, but it needs to be rebuilt. Your Traynor is sweet.


I thought I read an "all inclusive Canadian vacation". Good stuff.

JMPs were introduced late in the summer of 67

When I hear someone mention a 1968 JMP, 1st thing that comes to mind is an old 4 hole plexi - Non Master Vol Marshall amp - not a newer 70's JMP that is closer to a JCM800
'68 JMP's are the shiz!

Hi guys, thank you all for the information...
I'll check more carefully for the model and circuit...

And pictures! Pictures of everthing... the transformers, the chassis layout, the circuit board. A mint 1968 plexi is something of mythical and expensive so you have to be really careful. This board has a lot of people with a lot of experience to help.
