Hey, it's been a while since I lurked on this forum. Been playing way too much to build. Anywho, I built a Firefly amp some time ago which I use for my lapsteel. Sounds great with the break up through the 1x12 cab that I also built for it. What I'd like to do is add a small digital reverb circuit to the amp and be able remotely switch it on and off. I know, I know, the purists will have a field day with adding a digital circuit to an all tube amp. Besides that though, a couple of questions:
1.) Would there be any noise issues with putting the circuit right in the amp chassis?
2.) If the voltage of the caps are large enough, can I power the circuit with the heater from one of the tubes?
3.) To remotely turn the reverb on and off, I assume I'm going to need use 12V DPDT relays and use GEOFEX remote indicating bypass schem?
4.) Anyone have a PCB layout or perf layout of the relay bypass system? I'm not so good with schematics.
Thanks for any assistance.
