The MXR Bonamassa FET Driver manages the herculean feat of packing the smokin' tone of one of today's great blues players into a compact pedal. Crafted on the foundation of a cascading op-amp gain stage into a FET gain stage to emulate a hot tube amp, the unit features easy level and drive controls, high and low boost/cut controls, and a Hi-Cut button to stamp out pesky high frequencies fuss-free.
