Wampler Gearbox Andy Wood Signature Overdrive.

Gearbox features modified versions of two of Brian Wampler’s best loved drive circuits: the Tumnus and the Pinnacle. This combination makes the Gearbox one of the most versatile dual pedals Wampler has ever created.

Channel 1 (based on the legendary Tumnus) is a perfect addition to any board setup and any playing style. Its versatility allows you to stack it with another pedal to help push or shape the total amount of gain, use it as a stand-alone overdrive, or as a slightly dirty boost to push the front end of your amp over the edge. Channel 2 (Based on the Pinnacle, one of Brian’s most popular distortion pedals) delivers that legendary “Brown Sound”. The three band EQ lets you dial in your soaring lead tone while the unique noise gate keeps the clarity on point. Stack both channels together for tonal bliss - warm, yet brutal grunt; delicate and controllable harmonic overtones; beautifully defined distortion that cuts through the mix.

The Order switch lets you select which pedal comes first in the signal chain. For ultimate control, connect both sets of inputs and outputs to an external switcher to mix or match in parallel or series. Andy named this pedal the Gearbox as it was designed to be the driving force behind your sound.
