The Moon Op Amp Fuzz is a supermassive destroyer, spinning galaxies of gain. Tidal wave bass response gives you tones heavy as gravity itself. The filter control offers an expanded range of usable tones and the filter switch gives you three distinct EQ phases: Scooped Mids 'classic', Flat EQ, or Full Range. Feed the Moon Op Amp Fuzz with your favorite drive pedals and unlock worlds of complex tones.
