Rock/Jazz Switch

[Structo]

I know I sound like a broken record but the Bright on Clean mod is a very good mod.

Plus you don't have to drill any new holes.

Three position switch:

down - off
middle bright - on
up - bright on clean only - off on OD.

I think I have a 120pf bright cap there.
It does require another relay though.

But I run the preamp volume up around 1:00 so the bright cap isn't too pronounced, but just enough to to help.
