I'd thought fer sure that I'd posted this design before, but can't find it. (I know that I did because someone loved the reference handle that I used.) The original post has apparently been deleted. Nah, found it. Here it isThis is a mini toggle based design suitable for a Strat, Tele, or any three single coil pickup guitar. It can also be used with humbuckers, any series/parallel/splitting of the humbucker is external to this circuit. I did the first instance in a MIN Deluxe Nash Power Tele. This had 8 mini toggle switches; from the top row left they are: Piezo phase, Structure Drive, Middle phase, Neck phase, from the bottom row left they are: Mag/Both/Piezo, Bridge Ser/Off/Par, Middle on/off, Neck Ser/Off/Par. The drawing actually shows how it might be laid out in a Strat. It won't do the M*(B+N) or M+B*N combo's, but will do all others including B*(M+N) and B*M+N. Note that series requires two pickups in that mode or nothing happens (Neck and Bridge or one of either and Middle ON). The middle pickup is in parallel when ON unless one or both of the other pickups are in series, in that case, it's in series with them when ON. When the neck or bridge is off, the respective coil is shorted This can be alleviated with the usage of different (as in $10 more expensive) switches.

Goodmorning everybody, I just finished Chris's ToggleCaster !!!!!!!!!!!!!!! Thanks !!!!!!!!!! It's working perfect and is the easiest way of changing combinations on stage !!!!!!!!!!!!
Cheers Chris !!!!!!!!!!!!!!!!!

I've searched all over this site but I just can't find what the drive switch is for, would you mind filling me in?

You won't find any description of the drive switch on this site (except in a few of my posts).
In this design, due to the relative simplicity of the switching scheme, there is no intrinsic way to differentiate between B*(M+N) and (B*M)+N. In the first case the bridge is driving the parallel combination of the middle and neck. In the second case, the neck is in parallel across the bridge and middle, which are in series. Since this was a series dominant structure, a way was needed to change between series and parallel dominant, hence the drive/normal switch.
When the bridge and/or neck is in drive, when it is selected for parallel, it is placed in parallel with the middle pickup's paths to out and common, and it (whether or not the middle is selected) can be driven either singly or as a parallel pair by the pickup on the other side of the middle pickup.
When the bridge and/or neck is in normal, when it is selected for parallel, it is placed in parallel with the paths to out and common, and it is in/parallel regardless of any other pickup selection.
In the ToggleCaster drawing there are four schematics (which are quite close to how one would wire them). The left one uses a DPDT for switching both the bridge and neck into a drive or normal structure.
The next one uses a DPDT ON-ON-ON 3 position toggle to select normal for both the bridge and neck in the toggle's middle position, and either bridge drive or neck drive at either side position.
The two on the right indicate the wiring if no drive/normal switch is used, and both hard wired solutions are shown.
