I've wired a guitar using the lonestar schematic here:
I have just have two questions. The first one is, how does it actually coil tap 'automatically' at position four if red/white are soldered together on one of the poles?
Secondly, I've added a coil tap switch to this so I can coil tap the humbucker in position five if I like. I've put a wire from the pole on the 5-way to the common terminal of a DPDT push-pull pot. The white wire (-) from the humbucker is wired to that same terminal and the red wire (+) is wired to the down-position terminal. This achives the same as soldering white and red together on the 5-way terminal in the down position and then splits them on the up position.
I've only 'tap' tested the guitar but this combination appears to work except in position four with the tap switch turned on.
What appears to happen is the screw coil is tapped 'automatically' in position four with the coil tap off but the push-pull is tapping the slug coil, this appears to make position four with the push-pull up the middle pickup only.
I haven't strung it or played it yet so it all might sound 'thin' and horrible due to phase issues but in theory, I think this is right.
Any other ideas on how to tap the slug coil or make position four include a bridge pickup when split?
