Electro-Harmonic Micro Q-Tron. No issues, mint condition. Box and docs included. Simple and effective for getting those funky quacky sounds from bass or guitar. 3 knobs: Drive, Q and Mode. The Drive control sets the filter sweep sensitivity, the Q sets the frequency peak of the filter. Mode gives a choice of 3 filters, High-Pass, Low-Pass and Band-Pass. Takes a standard 9V power supply - same as Boss pedals.
