We've had a few folks using rotaries with HBs recently. I had this scheme sitting in my schematic files, and I can't recall if I ever put it up here before or not (old age sets in again!). If it's a duplicate, I apologize, but I'm pretty sure I hadn't posted this before. Couldn't find it, anyway. So, I'm throwing it up here so that someone will vet it. If it's good to go, I'll repost it in the Schematics section for future reference. If it's a no-go, then back to the drawing board for me . . . But I think it's OK. The idea here is that this would be used on a single HB Strat, a la EVH, or perhaps on an LP Junior with the single HB. It has a Volume control, a 3P4T rotary switch to select from the most useable HB sounds, and a second rotary (DP4T) used as a Varitone-type switch instead of a tone control. This provides three cap options plus a bypass setting. It uses a 1H inductor as well. Thus, on a Strat, all three std. pot positions would be used. On an LPJ, you'd need to drill a third hole. Cap values could, of course, be subject to experimentation.

Doood,
Diagram vetted. Great scheme.
I suggest you mark which coil is north and which is south, for completeness sake and to aid wiring.
You don't need a double-pole rotary for your varitone, only a single-pole. How comes you used a double-pole?

Thanks for the set of eyeballs on this, asmith!
I used a DP switch for the Varitone because the scheme, when I first did it, was going to go into a Strat that I have, and the parts box had a few DP4T rotaries left over from earlier things, so I thought to use one of those. But you're right, it would be simpler without the second pole and not really needed.
I will label the coils before reposting it in the Schematics. I thought to make this available since we seem to have a spurt of rotary-based projects afoot.
