Deep switch "on", bass knob boosted to two o'clock, upper mid switch on "on" and cut to 10 o'clock, treble straight up (with broken-in strings). Big and fat, but still clear.

I find this very interesting because I've been messing with one of these with my P Bass, and the settings I've settled on are identical to yours, though I think I kept the mids a little closer to 11 o'clock.
