From the vendor
Our take on the EQD Bit Commander.
A analog guitar synthesizer with 4 octaves – an absolute army of noise!! Best with a neck pickup and even better with a fuzz or drive infront of it!
Controls
The Base, Sub, Down, and Up controls work as independent blend controls.
• Level – Master output volume
• Filter – Overall tone for the pedal
• Base – Adjusts the level of the root square wave
• Sub – Adjusts the level of the -2 octave voice
• Down – Adjust the level of the -1 octave voice
• Up – Adjust the level of the +1 octave voice
