hold all the strings down at the highest fret and adjust the JB pickup height so that the pole pieces are about 1/16", or slightly more, away from the strings.
You don't want the strings to hit the pole pieces when you play or you'll get all kinds of nasty clicking noises. Pickup adjustment isn't really any different whether you play distorted or not.
If you still have the problem, after setting the pickup height, check your tubes.
