Passive volume foot pedal designed for guitar, bass and other instruments that controls volume using a passive 250k potentiometer with a high life cycle for reliable, quiet operation. Tone is maintained at any volume, and the special tone circuit retains high-end clarity as volume is reduced without becoming dark or muddy. It does not require any batteries or other power sources. Pedal provides a standard 1/4" input/output, as well as a tuner jack that allows silent tuning during live performances. Base and pedal are made of heavy-duty die-cast aluminium, with a durable hammer-tone powder-coat finish on the base. Dimensions: 213 x 89 x 66 mm. Silver colour.
