Here’s how I use the micro-pog as a bass player (and it’s been a mainstay on my board since I got it 3 years ago or whatever):

For a basic “thicken” sound, I max the dry, set -1 at 11 o’clock, and +1 at 9 o’clock.

For an “8-string” sound, I play through the neck pickup of my Ricky with dry at max, -1 at min, and +1 at about noon.

When I play guitar solos on my bass, I’ve got dry and -1 at min, +1 at max, into a metal muff with the top boost engaged and at noon.

For a 12-string sound, I’d max dry, -1 at min, +1 to taste (starting around noon, it’s going to depend how your amp is eq’d)

For Jack White, I dunno, I’d start with dry at min, -1 at 3 o’clock, and +1 at noon, into a big muff, into a vintage low-wattage tube amp. Replace big muff with metal muff and tube amp with sunn beta lead for a passable King Buzzo sound. Helps if your guitar is made of aluminum.
