My JCM900 has 4 bad pots and the repair costs are a little high for me. I've been trying to find pictures of the inside of the JCM900, but I can't find them. I want to know whether or not the pots are soldered to the board or are offboard components, litterally. I know that I can unsolder and resolder pots, but if they're onboard, it'll be a whole lot harder and I'd rather leave that to the pros.

It's a JCM900 100w Dual Reverb, I think the 4001 model.

you know, you could just open your amp and check yourself couldn't you?

from memory, they're all all mounted to the pcb. Its been a while since I was inside a 900, but i'm about 95% sure.

To be honest, its not all that much different to do. I find it easier.

Edit: wasn't the 4001 a JCM800? or do you mean the 4100?

how do those marshall handles compare tonewise to, say, mesa handles?

no, it's a 900. I might mean the 4100. It's the 100watt head. I don't know, there'a about a thousand parts to this things name...
"Marshall JCM900 Lead 100w Dual Reverb 4000"... yeah, simply put: 100watt 900 head.

yes, they are soldered directly on the PCB. don't be afraid of opening your 4100, not difficult at all. but make sure you discharge the filter caps!
