Pick an amplifier. I'm trying to figure out what the circuit that "surrounds" the reverb circuit is doing. This is usually the tube section V2 with the reverb tubes being V4 and phase V5. The input and drive are V1 with the FX loop V23.
Actually I have a mesa amplifier and I am wanting to have a hard bypass for the reverb and fx loop. There reason is because they are not needed and I want to compare the tube sound without these sections. The fx loop does have a hard bypass but the reverb does not.
V1 and V5 are absolutely necessary. V3 and V4 are not. I do not know if V2 is some type of extra drive/buffer for the reverb or if it is the final preamp stage.
If V2 is necessary then I should easily be able to take out V3 similar to how the fx loop is hard bypassed(DPDT switch) else I can include V2 in the hard bypass and remove it too.
I am also curious if it would be possible to replace the tube sections in the reverb and FX bus with transistors? This would save tubes and increase the fidelity. That is, instead of bypassing the tubes I would just exchange them with a transistor based circuit.
I was also thinking about adding a jfet input stage. Would this be a good idea? Also instead of bypassing the channel 1 tone when moving from the clean to the distortion channel why couldn't I mix them? This would simply require adding a pot instead of the switches and would offer more potential. Although here relays are used for the switching so it would be more of a chore.
