I liked the cleans but thought there was to much compromise and some room for improvement.
I added relays changing to:
15uF V1a+b on cathodes in clean mode (5uF in OD, could probably be lowered some).
Cap over mid switch is changing to as low as 270pF in clean mode.
2000//270 pF=237pF or something
I also think the clean sound better without LNFB so I´m probably going to switch that out in clean mode too.
Bright cap was lowered to 100-120pF or something lower value.

Also on cleans I like the master really high and 1st volume as low as possible. Therefore I added another volume (pre-gain) in the FET input hole so that you can push the OD much more (than the normal clean volume setting) when switching to OD mode. This is also swicthed in with relays in OD mode. It is just a simple 1M audio POT connected as a variable resistor between volume ground lug and ground. Does that really work? Try it. You will like it. In clean mode volume ground lug goes directly to ground.

But I am really a fender guy so perhaps I have lived with scooped mids for to long :D
