Top-switchable stacking order
Lets you change the order in which the two drive circuits are stacked.

Independent shopping perspective
Wampler’s Gearbox is Andy Wood’s signature dual-overdrive pedal, combining modified Tumnus and Pinnacle drive circuits. A top-mounted stacking-order switch changes which circuit feeds the other, letting you set the drive arrangement from the pedal itself. Dual inputs and outputs provide additional routing connections, and a noise gate is built in. It is a compact way to place two distinct modified drive circuits and their selectable stacking order in one pedalboard position.
