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! :D ;)

Thank you!
I still buying parts and working to get my layouts digitalized so I can order the panels. The prototype Hermansson 4x12 is in the making right now so thing are going forward. I'm not doing any big PA rebuilds anymore, they take too long time to do and I need that time to build the production series.
