The DOD Gonkulator offers independent Gain, Distortion, Output, Frequency and Ring controls. It features true bypass circuitry, an updated PSU jack and vintage-style aluminum chassis. True bypass allows your tone to remain pristine even when the DOD Gonkulator is off. This is a big difference from the original, which would color your bypassed tone and the modern 9V DC power supply input makes the pedal more pedalboard friendly
