Fernandes Sustainer humbucker assembly with a Single Coil Size Sustainer Driver and a Seymour Duncan Cool Rails stacked humbucker encased in a humbucker frame.
 
Supplying the sharp 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.
 
You can use this assembly to replace the Sustainer driver already installed in your guitar, it is compatible with older Fernandes Sustainer systems.
 
The Sustainer circuit board is required for the Sustainer driver to work. It will not produce any sound or sustain effect by itself.
 
We carry the full Sustainer kits, if that's what you are looking for.
 
Sustainer driver is made in Japan.
