Hi, I'm new and I have a Fender MIM Jazz and tried the parallel/series mod with a push/push DPDT switch. The sound I wound up with has great mid growl but bottom end just ain't happening. Also when in series the volume is more quiet(lower). I thought maybe I wired it wrong and went back and rewired it, hardwired in series. Still sounded the same. I have a stock neck p/u and a Quarter Pounder bridge p/u. Could this be a problem. I will eventually get the QP neck p/u. Anyway I went back and rewired it using the attached diagram. Could somebody please help me? Sorry for such a long post.
