But he left some questions unanswered
the mods he told me to do are way out of my knowledge.. I sent them to the tech and he is going to make sense of them.
He told me this though:
volume (1st knob) disabled by replacing the opto-resistosr with fixed resistors (this is so the overdrive channel is only channel)
--change the whole tone stack and the cathode bias RC/plate load resistors on the tube stages before and after the tone stack to standard fender twin specs
the amp has 4 tube stages, and he said this allows him to get the preamp clipping he's so fond of (as am I).
To someone who understands this, does it make sense?
