I leave my 55-94 DIP switch set at default. However, I run my mid control knob at the full cut position. Bass is almost always flat, maybe a bit of boost, treble is usally flat. Coil tap switch usually centered with the blend knob rolled back slightly toward the rear PUP. If I want a more Jazz-like tone, I put the coil tap back to the bridge coil only. This is primarily with TI Jazz Flats. Sadowsky Flats need a bit of bass boost, but I still leave mids fully cut on the bass. Not a fan of honky mids. I seldom use eithe PUP by itself, but I will occasionally set the coil tap to the forward position for a bit more bass. These settings work well in the studio or live.
