Hallo,
here are the results of my profiling session today.
For the first time I was using a Jet City load box, so I turned those amps up to 11
Amps:
1970 Marshall JMP Superbass 100W -> JMP
1985 Marshall 2205 JCM800 100W -> 800
1974 Fender Super Reverb -> SupRev
Signal chain:
Amp - > (some pedals) -> Celestion Greenback speaker -> Shure SM7b off and Shure SM57 on axis -> Chandler Germanium preamps
Have fun!
