Any thoughts on using a Super Reverbs’ reverb tube circuit for an extra ‘cascaded’ gain stage? I have a super I’ve converted to a 2x10, and it has the rob robinette ‘lead channel’ mod done to the normal channel. While I love some fender reverb, the tank and connections always go bad and I’m tired of fixing it. Could the reverb tube signal path be repurposed as a parallel, overdriven gain stage, blended in with the reverb knob? I’m not a pro engineer so waxing philosophical.

With some figgerin', you may be able to turn it into something like a Garnet-style Herzog circuit. Double bonus points if the amp already has a pedal activated reverb on/off button.

Look at the 1st Mese Boogie amp. That's what he did.

I tried it back in the 1990s. I thought it sounded like crap.
YMMV, and of course you might add some components to EQ this path to sound better than what I experienced way back when.

Notice also that Randy didn't stay at that simple approach, but continued to refine circuits to generate preamp distortion for another four and a half decades. It appears he thought there was ample room to improve on this approach.
