This pedal offers amazing capability in a passive effect circuit: four unique voices in a single passive pedal. Useful for altering the voice of basses, guitars, and virtually any electric instrument. A 9v battery is required to make the LED's operate but the pedal's voice settings will work regardless of the battery's state of charge.
The pedal shown in the images includes a separate on/off switch for the LED's but this can also be incorporated into the input jack as found in most active pedals.
