Will this work ?

Not real familiar with coil taps but I looked up some info and came up with this. I also put a tone bleed and Fenders "greasebucket" tone circuit in. I'd like to try this on my frankenstein guitar.
If you don't think it'll work let me know what I missed.

Wire it up, hook it up, crank it up, and if it dont scream like hell from straight to guitar to amp, then it didnt work

Generally your positions @ your switch work their way from back to front like this:

1. Bridge
2. Bridge (split to single coil)
3. Bridge + Neck
4. Single coil (outer coils)
5. Neck

I'm alittle confused about a few things though.
The Bridge + Neck, is that Full Humbuckers?
The Single Coil (outer coils) are the bridge + neck split into single coils right?

Assuming that the upper pup is the neck and the pins on the switch go 1,3,5,COM from top to bottom. In schematic jargon these labels are known as reference designations and pin outs.

Your neck pickup will only have coil split in position 2.

The .001uF capacitor will only have an effect as you turn your volume down.

Yeah, I was intending on neck coil split in 1 position only. I drew it up 1-5 from the bottom up. I'll check the switch out before I wire it up. I never used that .001uf cap before but its supposed to maintain treble as you turn the volume down. In other wordes keep it from mudding up. I got a 5 postion selector on an old pickguard I'll desolder and give it a go.

1.Bridge humbucker
2.Bridge and neck full humbuckers
3.Neck humbucker
4.neck upper coil/bridge lower coil
5.bridge lower coil

I think I drew my switch backwards but if I get one in my hands I'll get it right. Position 5 will pretty much be worthless but position 4 is what I was after. Position 4 should give me humcamcelling single coils in parallel.

You want your switch to go from your bridge position's #1 and work your way forward ending with either a full neck humbucker or a split coil neck.
That is the standard, but of course there are no rules.
It just gets less confusing when you wire it that way.

The hum cancelling effect will be lessened by the difference between the 2 pickup's output levels. If the neck pickup has about half the output of the bridge (when no string signal is present), it will only cancel about half of the noise signal. This will be roughly proportional to the DC resistance values.

You may want to consider that schematic I put on here a few months back that will rewire the humbuckers as parallel in certain positions. That will be full humbucking and give you real nice quack in the tweener positions.

It would require a Fender Superswitch.

Here's one thing you could do:

1--Bridge (pickup wired normal series humbucking)
2--Bridge + Neck (each pickup wired parallel humbucking)
3--Bridge + Neck (each pickup wired normal series humbucking)
4--Bridge + Neck (north coil of bridge in series with south coil of neck--humbucking limited)
5--Neck (pickup wired normal series humbucking)

Positions 1-3-5 are the standard for dual humbucker guitars. You can pretty much wire the 2-4 positions any way you want.

After I got a switch I saw the left side was correct but the right side I had to move the bridge coil tap to the lowest position. I hooked it up and the curcuit worked. There was a little hum in position 4 but not very noticable. The downfall is I think the Carvin M22 humbuckers were the wrong pickup to try to get a good single coil sound out of. It sounds good but not anywhere near a nice bluesy tone like on my strats. A nice bluesy tone is kinda what I was after unfortunatly. It may work better if I change my amp/effects setup a little. I didn't do the coil tap or the greasebucket tone curcuit yet I just did the switching so far.
