People do this why dont you use a switch like on the lp gibsons then you can have both on or seperate controls then you have a great place for the ground from the pickups and jack.
Have any of you tried the smaller tone pots with humbuckers going from 500K to 250K and did you like it ?? Dumb cap question because I always forget 47NF on my cap checker is the same as .047UF right
