Great condition for it's age minus the expected bumps and dings. Working great from a 9v battery, though the other power input remains untested. A classic analog "auto-wah" pedal from the company's "block logo" era. It is highly regarded for its simple two-knob design and its ability to produce thick, funky filter sweeps favored by funk, soul, and disco artists. A very cool pedal, with the original operation manual.
