George Dennis GD135 Tube Distortion-Volume Pedal

The GD135 Tube Distortion-Vlume Pedal from George Dennis uses a totally different system than other distortion effects. Its 12AX77025 tube is fully powered, giving you a wide range of distortions that evoke an overdriven tube amp while preserving the native sound of your instrument. Controls include low, mid, and EQ knobs; effect level, drive, effect mode, and volume for tons of tweakability. Unit is powered by a stabilized AC power supply or 9VDC with a minimum of 150mA (adapter not included). Unit is protected if you plug in a supply with reversed polarity.
