An exclusive Big Knob original, the Rock-Ola overdrive was specifically designed to maximize the full potential of fingers and plectrum. Used with your guitar's volume and tone knobs, it produces an extraordinarily wide range of overdrive and distortion palettes. And while the design focus was on single-coil Strats, Rock-Ola also sounds terrific with humbucker-based guitars.

  Rock-Ola features:
Versatile overdrive that accentuates playing dynamics
Controls for Volume, Gain and Tone
Fully hand-wired analog circuitry
Compact MXR-sized enclosure
True bypass 3PDT switching
Bright indicator LED
Accepts standard 9V pedal adaptor
9V DC battery clip included
