Wiring a Geddy Series/Parallel

  1. Hi all,

    I did the series/parallel mod tonight to my Geddy Jazz with a push/pull switch. The problem is, the bass works fine in parallel, but when I switch to series, it sounds like only the bridge pickup is on (it sounds exactly like the bridge soloed in parallel). After looking at the wiring again, I think I may be using the wrong ground. The Geddy has three wires coming from both pickups. There is a thick white, thick black (both cloth covered) and a thin black wire. I used the thin black wire for wiring the push/pull switch. Did I use the wrong ground? I know that the Geddy uses the vintage style pickups.

    I had similar problems. That thin wire is a ground for the copper grounding plate under the PU. You need to use the black wire that is the same size as the white one. Good luck.
