I just got a 2 wire HB to replace my 4 wire HB. I only ran the old one in series anyway. When I had it out last time, I noticed that one of hte magnets was broken, so I ordered an inexpensive replacement. So the bass is an old Kramer Duke-- volume/tone and a 3 position p'up selector. So, where should I solder the white wire? the bare wire? Will this bypass the switch? Thanks for your help. I'm not much of an electronics guy.
