Greetings - Last year, I bought an Epi Black Beauty 3 with the idea of modding it. I picked up GFS VEH bridge/neck and GFS Mean P90 neck. I wanted to be able to use the P90 in series with the humbuckers. After extensive research, I decided I would go with the Free-way 6 way switch. I wrote to the company and Alasdair kindly provided the following schematic (see below). Briefly, the following scenarios are available: 1 - Neck 2 - Neck/Bridge (parallel) 3 - Bridge 4 - Neck SC + P90 5 - P90 6 - Bridge SC + P90 There are 3 vol pots and 1 master tone pot with a push/pull. Pulling the tone knob should put the P90 in series (rather than parallel). My problem is that I have wired it as per the diagram. I just can't seem to make it work. I don't know if it's my wiring (probable) or the schematic. I was hoping that throwing more brains at the problem would identify a possible schematic problem. Thanks!
