Supplies the overdriven power of two highly coveted amp stacks in a single housing. Pros and tonechasers have been combining amplifiers for years, blending their sounds together to open up new tonal palettes. The FOD Drive is the result of the efforts of the MXR team of engineers, painstakingly recreating each amplifier in pedal circuit form, then fitting them into a single housing as separate channels?High Gain and Crunch Gain. Each channel has its own gain and volume controls. The blend control then allows you to set the mix ratio of the two signals?just like having two separate amps running into a mixer. 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. Experience the invigorating potential of playing through two ripping amp stacks right from your pedalboard.True hardwire bypass. Powered by 9 volt battery or AC adaptor (ECB003).
