In this article, Pete Biltoft at Vintage Vibe Guitars gives an in-depth explanation of humbucker coil splitting and tapping. You may also find my earlier posts useful: Humbucker Wiring and Coil Splitting.
Thanks again to Pete for the permission to post this here!
The topic for this tech tips newsletter will be Coil Splitting and Coil Tapping.
Coil Splitting and Coil Tapping are two methods which can be used to extend the range of tones on can get from a magnetic pickup.
First, a few definitions:
Coil splitting refers to disabling one of the two coils of a humbucking pickup by shunting that coil’s output to electrical ground.
Coil tapping is most often used to describe a single coil pickup which has a coil start and more than one coil end (output tap).
Because I intend to devote most of this article to Coil Tapping, let me start with Coil Splitting.
