EarthQuaker Devices The Warden V2 Optical Compressor Guitar Effect Pedal

Dimentions: 4.75 x 2.50 x 2.25 in. (121 x 64 x 57 mm) with knobs Current Draw: 31 mA Input Impedance: 1 MΩ Output Impedance: <1 kΩ Switching: This device is true bypass and uses electronic relay-based switching. Audio will not pass without power. Power: This device takes a standard 9 volt DC power supply with a 2.1mm negative center barrel. We always recommend pedal-specific, transformer-isolated wall-wart power supplies or multiple isolated-output supplies. Pedals will make extra noise if there is ripple or unclean power. Switching-type power supplies, daisy chains and non-pedal specific power supplies do not filter dirty power as well and let through unwanted noise. DO NOT RUN AT HIGHER VOLTAGES!
