The Keeley Fuzz Bender is a 5 knob, 3 transistor modern fuzz using a combination of high-gain silicon and silky smooth germanium. What makes fuzz better? Active EQ. Using two gyrators as an active EQ gives you the ability to create massive fuzz tones not possible with typical square-wave boxes. Pummel your amp with over 20dB of boost/cut at 100Hz and 10K Hz. The Fuzz Bender is built around vintage Japanese germanium to create its monumental fuzz tones.
