The MXR FOD Drive supplies the overdriven power of two amp stacks in a single housing. For decades, players have been combining amplifiers on stage and in the studio. Now, any player can easily recreate the amp-blending experience right from their pedalboard. Each channel has gain and volume controls so players can dial in just the exact sound for each side. The blend control then allows you to set the mix ratio of the two signals — just like having two separate amps running into a mixing box. The tone knob sets the EQ for the overall output signal, and the scoop switch allows you to choose between flat, scooped or boosted midrange voices.
