Here's my attempt at the holy grail. This mod starts with DavePlayBass's (DPB) Series/SC-inside/Parallel, but makes a few changes. First, it eliminates the pup-selector switch. This is replaced with a stacked, concentric volume pot. No need to switch pups on or off. Just roll the vol up, down or off for each pup individually or together. DPB's mod replaces the stock 2-way 4PDT switch with a 3-way 4PDT switch. This mod replaces the the 2-way 4PDT switch with with two 3-way DPDT switches. One goes where the pup selector switch used to be. This one works like the top half of DPB's switch and controls the neck pup. The 2nd goes where the old S/P switch was. This one works like the bottom half of DPB's switch and controls the bridge pup. Other than that, I have tried to be faithful to DPB's diagram. There are a couple of other items however that are worth mentioning. I had to change the tone circuit path because of the additional volume control. Stock wiring goes from the pup selector switch to treble pot to bass pot to volume. My mod requires the the volume pots to come first, since they replace the pup selector switch. So, this is wired... V/V-->T-->B My mod also replaces the stock Bass pot with a push-pull pot. With the pups in parallel, and the push-pull in the "up" position, this adds an SC-outside setting. Two other itty bitty changes to stock... There's a cap on the stock vol pot. I eliminated that. I added a resistor between the tone circuit and the pre-amp. The reason for those two changes have been discussed elsewhere... So, now that I have drawn it, and gone through it several times with a pencil, I thought I'd post it (a) to see if anybody finds something wrong with it and (b) for use by anyone else who'd like to try it. Couple of conventions to note... I don't have a great drawing program, so solder-posts are denoted by a black dot. All solder connections are at a black dot, except for connections that are grounded to pot housings, which are denoted by a green dot with a "down" arrow. Caps are orange footballs with the value noted. Resistors are pink circles with the values noted. All wiring colors are as close to stock as I could keep them...with one exception. used a blue (rather than white) wire between the state-selector switches and the volume pots. There are no blue wires in original G&L wiring. This was just to avoid confusing the white wire from the pups with the "out" wire to the tone circuit. OK, if anyone finds an error, I'll correct it and put up a new diagram--thanks in advance to anyone who does. If no one does, hope this is helpful to somebody ;-) This owes a huge debt to the meticulous wiring diagrams created by Ken Baker, and DPB's mod documents. Also to Ken, Dave, Jim and all the others who have patiently answered my questions in other threads.
