The Seymour Duncan TS-1 allows you to expand your tonal palette by accessing three unique tones from a humbucker, thanks to the TS-1 mounting ring that holds two small switches. For use with nearly any humbucker and Trembucker pickups with four-conductor cable, Seymour Duncan or otherwise. It is the perfect match for the P-Rails.
This "stealth" pickup switching device allows you to access series, parallel and split wirings with a standard humbucker. And it's easy to install. Just solder your pickup leads to a small color-coded circuit board. That's it. Push the two switches towards each other for standard series wiring; away from each other for parallel wiring; and both towards one coil (either one) to shut that coil off.
