Seymour Duncan SFX -01

SFX -01 description:

The SFX-01 was Seymour Duncan's first foray into the world of foot effects.

The Seymour Duncan SFX-01 is designed specifically to work together with the pickups in a guitar to achieve optimum gain and resonance for all tonal applications. Works with all musical styles.

By rotating the gain control knob you can add pure, flat-EQ gain, ranging from 6dB to 25dB! The Resonance Switch drops the resonant peak of a single coil pickup up to 5KHz, making a single coil sound like a full and fat humbucker. Features fully discrete Class A circuitry along with true bypass. Comes in a heavy-duty steel chassis and runs on a single 9 volt battery. For Resonance Switch to work properly, the SFX-01 must be first in the signal chain using passive pickups and a standard guitar cable — not a wireless unit.

Famous users of the Seymour Duncan SFX-01 include Michael Landau, Peter Stroud & Todd Wolfe / Sheryl Crow Band, Richard Evans & David Rhodes / Peter Gabriel, Gary Rossington, Rickey Medlocke & Hughie Thomassen / Lynryd Skynyrd, Greg Hetson / Bad Religion, Phil Campbell / Motorhead
