Features Level Sets the volume of the overdriven signal. Filter Controls the amount of high frequency content in the fuzz signal. Blend Mixes the clean input signal with the overdriven signal. The clean signal remains at unity gain while the volume of the overdriven signal is set by the Level knob, allowing for fine control of the blend ratio. Duality Mixes two discrete fuzz circuits. Set it at minimum for a pure gated saw-tooth wave, or crank it up for a tighter high gain fuzz. Dimensions 11.3×7.5 cm (4.45×2.95 in)
