Seller's description

in good condition. With box. Key Features and Controls Drive Knob: Controls the amount of soft and hard-clipping distortion, moving from a clean transparent boost to chunky rock crunch. Level Knob: Adjusts the overall output volume of the pedal. Spectrum Knob: A unique tone control that boosts bass and treble simultaneously when turned clockwise while leaving the middle frequencies untouched. Internal Bass Cut Switch (BC Model): A switch located under the battery cover that rolls off low-end sub-bass frequencies to prevent a muddy sound when using humbucker pickups. Power Flexibility: Operates on a standard 9V battery or a 9V to 18V DC power supply for increased headroom.
