Up for sale is this Marshall JMP 2104 from 1981. I’ve rebuilt the whole preamp section and made some changes to the power amp and the power supply. This amp has dual footswitchable gain and volume controls + a footswitchable gain boost. So you can reach four different levels of gain using the footswitch. It has an LND150 based effects loop. It still has the old good DALY capacitors who all measures excellent (ESR and capacitance). I’ve installed new Celestion G12-35XC in the 2×12 combo.
Here it is through the original 2×12 with the new speakers:
And here it is through my Malmberg 4×12 with Greenbacks:
