Thanks for the reply. I've been doing some playing around with it, and I've found that the actual power amp on this works absolutely fine, it's just obviously dry with no tonal control or effects, which are part of what made this amp sound so incredible. That said, what do you all think of the idea of buying another spider series amp, gutting the preamp circuit boards from it, then frankensteining the preamp from that into this chassis? I see those come up really cheap used all the time. I've looked into driving it with something like a high end multieffects pedal, but to have something that could replace what was in the amp to start, it would cost about the same as a whole used replacement amp.
