I’ve modded a Marshall JCM800 2204. It was modified by someone before who changed the faceplate and installed dual master volumes.
This amp was shipped from Germany without a headshell.
The old mod.
Removing the old components.
The tweaking process!
The new mod is in place!
I’ve rebuilt the whole preamp section and made some changes to the power amp and the power supply. I’ve also installed a Metro zero-loss loop.
I'm not using any pedals, guitar straight into the amp, no post eq.
TC G-major II in the loop for some delays.
Cab: Malmberg 4x12 with old Greenbacks.
Mics: Golden Age R1 mkIII, Tascam DR-40
