I'm building a guitar with 2 humbucker pickups....ordered a Ernie Ball 3 way EVH toggle switch(always liked their toggle switches best). It has a weird circuit board on it and was wondering how to wiring it with the 2 pickups? Toggle says on/on/on....is this correct? HELP? Note....I had to clip part of the board off in order to fit in lower strat horn cavity....just clipped what looked to be a ground from a metal washer that had a wiring running from it to pcm board....
