The Black Cat Super Fuzz is a modern take on the classic Univox Super Fuzz pedal, now with top-mounted jacks for a more pedalboard-friendly footprint. The balance and expander controls are essentially dials for the amount of fuzz added to the signal and the output volume, while the center tone switch goes from warmer, vintage-tinged to bright and fiery lead sounds. This raucous fuzz machine sticks a subtle octave-up signal behind the fuzz tone for a bright, biting effect that's amazing on leads and melody lines.
