It occurs to me that as I will only be using the clean channel of my B-52
AT100 that I may not be engaging all the preamp tubes. There are 4 preamp
tubes in it. V1 V2 V3 V4 slots. Could I just change one or two preamp tubes
get a better clean tone and forget about the others? Or are all 4 engaged
always?

The current flows through all the tubes all the time. Just because
you're playing with a clean tone doesn't mean you're not using the
tubes. Without the tubes, you wouldn't have a preamp at all, only an
equalizer.


Well, it depends entirely on the amp. If I pull the 12AX7 out of P1 in my Silverface Fender, I can still play through the Vibrato/Reverb channel and have the amp function. And vice-versa. We need to see a schematic.
