v-4/vt-22 sensitivity question

[tdbassman]

Should note that I run my amp dead clean. The dirt pedals I use have active 12db HF cut at a pot-controlable frequency, so I can have a fat, sparkly clean tone, then kick in a high gain overdrive pedal that has a sharp cutoff at X.Xkhz so there is exactly as much high end as I want for clean and for high gain.

This is nice to know, but what I'm really looking for are cap configuration suggestions for PBass with flats. I use it for old school rock - for which Ampeg's are famous, and for big band. I realize sound is pretty subjective, but are there any schools of thought and has anyone have experience with this? I want to avoid continuously soldering / unsoldering from the board.

I've never thought of runing my guitar through the V4-B, as I've got some different (lighter) amps for that.
