It's tough to find these things without mods though.Ĭan you post a clear chassis pic? I'll post a pic of the "restored" chassis for you to compare. Michael_dba wrote:Right on!

I think that I only have 9 days to return the amp back to Vintage GC so I will have to move quickly to decide whether to keep this or not. This weekend I plan to make a trip to an amp tech determine what’s going on and if it is worth the investment. All this was done with the Master set to 2.
I also did not notice a lot of tone change rolling the treble, bass, middle, or presence knobs from full (10) on or off (0). Also with the master at 2 and the preamp backed down to 5 the volume drop was considerable. I really didn't get a chance to crank it, but with the master at 2, it was not as loud as I would have thought as compared to my old 4104 JCM800 and I really could not get much gain out of it even with the preamp all the way to 10. The bottom casters are missing and the amps has been changed over to E元4's.įiring it up, tubes all light up, no hums, but pots are a little scratchy.
The speaker cloth only has one bad spot but no holes or tears. The cab is really in nice shape and so is the tolex. It appears have all the original components, transformers etc (I am no tech) but there are two extra holes on the top panel next to the two inputs that are plugged and one of the speakers output jacks is missing. Note that I bought this amp sight unseen from Guitar Center Vintage except for just a few pictures and knowing that I could return it if needed. A gem of an amp shipped out safely and promptly from our little shop here in Clarksville, Tennessee, to your front door.Well, I picked up the new amp tonight, got her home, pulled it apart, and cleaned it up. If you are looking for a really good sounding and reliable vintage Marshall combo, this 43 year old JMP 50 is top notch. This amp also has a pretty tremendous sounding clean that produces a nice dark chime and would be pretty ideal for pedals. The Master volume and Pre amp volume allows you to roll in a saturated signal at a reasonable volume and, of course, the more you turn up the Master volume, the more this amp comes alive. The overdriven sound of this amp is excellent and has a classic midrange thump with a round fuzzy bottom end that’s perfect for any kind of rock and roll.
This JMP 50 produces some stellar quintessential vintage Marshall tones. All transformers are original and the inside of the amp is nice and tidy (see photos). This Marshall functions perfectly, runs quiet and doesn’t produce any unnecessary noise such as scratchy pots, ground buzz, etc. This Marshall has been well cared for over the years and has been serviced and maintained frequently and belonged to the same gentleman for quite a long time. The metal faceplate has a slight bend in the corner by the JMP logo and the speakers have been replaced with a set of 1990s English made Celestion G12T-75s. This 1978 Marshall 2104 JMP 50 is in very good cosmetic condition showing signs of use and play wear throughout (see photos). Very good condition featuring 50 watts of power, E元4 power tubes, 12AX7 preamp tubes, two 12” Celestion G12T-75 speakers, gold metal faceplate with black text, two inputs - high/low sensitivity, plastic red and black rocker style power and standby switches, Master volume and Pre-amp Volume, black plastic vent mounted to the top of the cabinet, black rubberized handle, four black plastic protective corner caps, black grill cloth, white piping, white plastic Marshall logo in the center of the grill cloth and original black Tolex covering.
