    WTB - 2061cx cabinet

    I’m looking for 2x12” cabinets that were designed for the 2061. I don’t mind if they are loaded or unloaded as I’m looking to replace the stock G12H30s with other models. Looking for examples in the UK, ideally in the Midlands to avoid the expense and hassle of postage.

    WTB - Pre-‘73/PCB Super Bass (1992) or Bass (1986)

    I’m looking for either a 100W or 50W Bass head (1992 or 1986 circuits), ideally pre-PCB which I believe began in 1973. Essential maintenance is acceptable (bulgin to IEC, replaced mains selectors, caps) but replacements to the tone circuit (transformers, pots etc) would be a dealbreaker. I’m...

    Mojotone 78 JMP 2204

    Never built an amp before, but wanted to dive in on the new kit I saw Mojotone released. I decided on the 78 circuit from their own sound samples. I know my way around a soldering iron, but trouble shooting circuits is another thing entirely. (foreshadowing) Upon inspecting the parts on...

    Worth it to get an external power amp for JMP-1 or JCM2000 DSL FX Return Good Enough?

    Been using the JMP-1 through the DSL power amp for a while. One curiosity I've had for a while is whether or not I'd be better off getting one of those Marshall gold power amps. I always thought the DSL FX Loop had some weird tone-sucky quality when playing the amp itself with effects, and I...

    Fabulous disaster (family photo)

    I just got my 2555SL back from my former drummer’s house, so I thought I’d share a family photo. Yeah, it’s a mess. Oh, well. If I waited to clean it up, I’d never share a pic. Anybody else have a messy music room? BTW, I haven’t had the 2555SL in months, and I’m happy to report that it stands...

    NAD: 1977 Marshall JMP 2203, 6550's.

    Hello Everyone! As the title states .. I picked up a 1977 Marshall JMP with GE 6550's on 3/15/22. The amplifier had its filter caps changed with F&T's along with Sprague caps. The iron is all original ! I've searched & waited patiently for about a year for one to be available relatively...

    How much louder is a 50 or 100 watt JMP vs an SV20?

    I know amplifier wattage, headroom, and volume are peculiar subjects to be objective about but I'm sure someone on this sub has two or three of these amps to compare. I've played through a couple 1959s before but never dimed like I can with my SV20. I know the SV20 is loud but I regularly get...

    Marshall JMP1C -Thoughts?

    I just found a JMP1c for 580 dlls, which I think was a very good price, so I just went and bought it without ever having listening to one. Still haven't received it yet, but I would love if you could share your thoughts or experience with them. I also found out that they come in 8" and 10"...

    What pots are in the JMP Mk2?

    We've got a 50 watt jmp mk2 1987 model, I believe it's a 76 (H serial code) and all the pots are pretty bad. We've metered them and they've got a bunch of dead spots. I can't seem to find anywhere that says what the values are to replace them, Thanks..

    1976 - Marshall 2203 - JMP - Restoration

    Hello, I've recently acquired an old 76' JMP from a local rocker. He used this amp in a live setting over the course of a decade or so. It appears the amp has been sitting in poor storage for the last decade or two and I've been cleaning up the chassis and cab. I've just started to look at...

    1982 Marshall JMP has 4ohm or 8ohm, my cab is 16ohm, what should i do?

    I have a 1982 Marshall JMP 50w head. Its the Canadian model with the nice metal toggles. It only has 4ohm or 8ohm options on the selector switch and I have a 16ohm classic cab with 25w greenbacks. Will i be able to use this head and cab together? If so, how should the head be set?
