The legendary Fernandes 3-mode Sustainer Kit with a Single Coil Size Sustainer Driver with a Seymour Duncan Cool Rails encased in a humbucker frame.
 
Supplying the crisp tone of the Cool Rails for neck pickup sound (when Sustainer is off).
 
The Cool Rails neck delivers an articulate and full sound, much like a full-sized humbucker. Its medium output makes it a great sonic match for a Hot Rails, JB Jr., or any standard-sized bridge humbucker as well. Chords will be warm and articulate, with a subtle scoop in the mids, and solos will be fat and crisp. The dual-blade design provides excellent sustain, especially for string bending on the higher frets.
 
Hand built in Santa Barbara, CA, the Cool Rails for Strat single-coil sized humbucker comes with a ceramic magnet, 4-conductor lead wire for multiple wiring options, and is wax potted for squeal-free operation.
