The MF Drive is a unique, filter-based overdrive pedal that employs a Moog Ladder Filter, boutique FET amplifiers, and classic OTAs in its drive section making it highly reactive to input gain and picking dynamics. The bi-polar tone control and sweep-able filter work with input gain to offer each player completely customizable sounds from creamy British overdrive to cranked American tube amplifier and even fuzz. When the filter Peak switch is engaged and an expression pedal is connected, the harmonic content is shifted to the filters cutoff position adding tonal and dirty wah performance possibilities not found elsewhere.
