The Unobtanium from Crazy Tube Circuits is a dual overdrive/pre-amp featuring a Klon Centaur-inspired circuit with germanium diodes for clipping on the right side, and a Dumble-style amp-in-a-box on the right. The right side gives you the freedom to toggle between buffered or true bypass, and stock or modified drive circuit. The pedal features a passive effects loop, allowing you to connect pedal between the overdrive and amp side, or use the two sections as separate and independent effects.

Excellent condition. No visible playwear on the face of the pedal, with some scratches on the bottom of the unit.
