I've been rather pre-occupied with some things of late to concentrate on this, or anything constructive, but I managed to sit down and work out how I want her wired - I'll post a diagram in the next day or so but this is the basics...
2 x 500k volume pots, the original pup selector, Bill's (Sniper) original EB3 rotary switch and a double pole single throw switch with an XLR socket wired with stereo capability...
Rotary switch positions with an output to the pot...
1 - Reverse phase MB
2 - Normal MB
3 - Parallel coil MB
4 - Bridge side single coil MB
RD Artist pup out to 2nd pot
Both pups wired through a fairly standard pickup selector with output straight to one pin on the XLR - the double pole single throw switch will bypass the volume pots and each side will go straight to 2 pins on the XLR for straight to the board or running two amps... I have the ability to blend the sound on the Hiwatt as the inputs both produce differing sounds to the pre-amp circuitry and the balance control blends these two inputs...
