"The 500K will make your single coils sound much brighter, but with the resistors, your HB in dual mode will sound muddy..."

The resistors should only be switched in with the single coils, not with the humbucker -- so the humbucker by itself sees a 500K load and the single-coils see a 250K load. There will still be issues when splitting the humbucker and in the bridge+middle position (whether the 'bucker is in dual-coil mode or split) but that's true with or without resistors. Using resistors to trick single-coils into seeing a 250K load with a 500K volume is one of Martian's trademark ideas -- odd that no one's disputed him the dozens of times he's suggested it.

But the way the resistors are wired now, they're in series with the pickups, not in parallel with the volume pot. They should be increasing the impedance load to ground, not adding resistance to the signal flow. Because they're such a tiny value (470 ohms instead of the correct 470K ohms) they aren't adding enough resistance to really do anything, but one end should be connected to the switch lug where the pickup wire connects and the other end of the resistor should go to ground.

The treble bleed cap is wired incorrectly. It should connect the voume pot's input and output, not run from the third lug to ground.

"your 4 lead HB wire needs to be trimmed to a shorter length, also you cannot have bare splices, any splices should be insulated with shrink tubing, but Why are you splicing..."

What splices? White and black run to the splitter switch, green and silver to the back of the volume pot, red to the switch. I don't see any wire splices at all.

"Switch your Volume pot to a push /pull for single to dual HB mode."

Why? Having the coil-split push/pull on one of the tone pots is normal and common -- keeps you from bumping the knob down while playing. Plus using a regular pot for the volume gives you a nice large area for the ground connections.

"You only need a 5 way....remove the super switch as it is just making your project a nightmare."

I said that back in the 4th post in this thread. But he's already bought the superswitch, doesn't have a 5-way, and doesn't want to buy another switch and more pots and waste the investment he's already made in parts. Not having asked about what he needed before he started has complicated matters, but the components he already has can do what he wants.

The sloppiness I attribute to it being a work in progress. He's trying to figure out what goes where and just to get it to work. I assume he's going to tidy it up before he adds the ouput wires to the jack and actually installs the loaded pickguard into his guitar.

Hollis, again I suggest you start a new thread. But title it "Martian, please help with a wiring nightmare." He could wire your guitar the way you want with his eyes closed using your existing components (except replacing the 470 resistors with 470K resistors).
