Bass booster pedal. Now discontinued. A small scuff on the front, but otherwise fully functional.

"The Mole is a bass booster that helps bassists and guitarists unearth a sound that is positively subterranean. Based on the classic design, this updated pedal adds the same rich, low-end bottom while adding a 20dB boost to your signal. Whether you step on the Mole to get deep, ground-shaking drive or dial back the knob to add some texture to your existing tone, the Mole will dig wherever you tell it to."
