Check the listing for details. Earthquaker Devices Bit Commander™ Analog Octave Synth. Condition: New. Listed at 199.00 USD. Manufacturer's Description: The Bit Commander is a monophonic analog guitar synthesizer with four octaves of vintage square wave synth tones. Its no-nonsense interface makes it easy to add or subtract octaves to create a wide variety of sounds without having to dial in envelopes or oscillators. Ripping sub-octave thump, pulsing octave down, a lightly squared base tone and a swelling transformer based octave up all join together to make a single guitar sound like an army of olde tyme synths. Manufacturer's Specs: Dimensions: 4.75 x 2.50 x 2.25 in. (121 x 64 x 57 mm) with knobs Current Draw: 25 mA Input Impedance: 50 kΩ Output Impedance: 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!
