Bass.
Put your guitar pick up in neck position, and strum a power chord on the low E and A string. Start turning the dial on the up up, until you hear a "swell" in sound. Leave the dail at the point that you hear the swell (you may have to wiggle the dial to locate the point)
Mid.
Put your guitar switch in the middle position. Strum a powerchord on the middle strings (D and G), start wiggling the mid dial, until you find the point where the sound "swells", leave it there.
Treble
Guitar switch at bridge position. Strum a powerchord on the B and E (thinnest) strings. Turn the treble dial until you hear a swell in sound. Leave it there.
