th,
By definition, a humbucker is a center-tapped coil. The fact that there are two separate coil forms present has no effect on the overall device - it's still a pickup. Accordingly, you can try some of those ideas on any 3- or 4-wire humbucker(s) you might have laying around. (Or you could convert a 2-wire unit, if it hasn't been potted.)
There's no easy and/or fast way to install a coil-tap into a single-coil pickup, sorry to say. If that's your aim, let me suggest that you experiment a few times (like several/many times) on cheap pickups, before you attempt to go Nutz on a more expensive pup that you like.

sumgai is explaining the difference between the terms "tapped coil" and "split coil". Orville got it wrong, unless, as sumgai explained, you think of both coils as a single coil.
This is the kind of thing where SPICE modeling is very useful.
I believe this circuit was used in the Peavey T-60, and while it didn't take the guitar world by storm, those that have it generally like it. Without the cap, it's known as the "Spin-A-Split", and there's a diagram on the Seymour Duncan site.

Glassy, Right you are, and I did forget about the T-60, sorry to say. It's not just "essentially the same thing", it is in fact the result of Peavey being the assignee of that very same patent - check it out. While searching for a T-60 schematic (just to refresh my memory), I found a wealth of info on this topic here, at the Seymour Duncan forums. Some pretty well-informed posters there, IMO. Lest we forget to give credit where due (and to appease Unklmickey's memory), this is yet another contribution by none other than Orville J. "Red" Rhodes, who transferred several of his patents to Peavey, over the years. Check him out: en.wikipedia.org/wiki/Red_RhodesI've had some of his own albums, and I still have a few where he contributed no small effort. He had it going on. HTH sumgai |
