I’ve modified a Marshall JMP 2104. The whole preamp section is rebuilt and I 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.
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:
Best of all, you will find it under Member Classifieds!
