Gamma Drive

Overdrive with 2-band EQ

Gamma Drive is a germanium-enhanced overdrive with active Treble and Bass EQ controls. Achieving articulate, touch-sensitive performance characteristics via a unique mixture of germanium, LED and silicon diodes arranged to produce asymmetrical clipping, Gamma Drive offers overdrive rich in 2nd order harmonics, which creates sweet, blooming tone. Offering a range of overdrive from sparkling clean boost to a raging distortion, Gamma Drive was designed for versatile playing across a wide variety of musical genres.
