Distortion/sustain effect pedal specifically designed for bass guitar that delivers enhancements to the classic Bass Big Muff Pi pedal and provides more tone shaping options than before. It features Volume, Gate, Tone, Sustain controls, as well as Blend control that allows player to mix to taste the direct and distorted signals; foot-switchable crossover section with a variable low pass filter on the dry signal and a variable high pas filter on the distorted signal that provides the ability to sculpt the sound; and pad on the input that is switchable between 0 dB and -10 dB and ensures the pedal is optimized for use with both passive and active pickups. Crossover circuit, in conjunction with Blend control, also allows keeping the low-end clear and focused and the high-end bright and cutting. Pedal is equipped with 3 inputs: a 1/4" effect out, 1/4" direct (buffered dry) out, and XLR DI out for complete control of the output signal and sound; built-in noise gate with an adjust threshold that eliminates unwanted noise at any level; and tough, compact die-cast chassis. Pedal can be powered by 9 V battery (included), or optional 9.6 DC power supply (not included). Dimensions: 146 x 121 x 64 mm.
