"Gear Grinder" multi stage analog FET preamp/overdrive STEREO,The Gear Grinder pedal is based on the succesful Organ Grinder. It offers stereo in- and outputs and holds an improved gain circuit, enabling more subtle (cleaner) drive settings.
When channel 1 is plugged but channel 2 isn't, the output signal of channel 1 is also sent to channel 2.
