New, Unused Fulltone OCD-Ge Overdrive I never ended up using it after I bought it! It's a new, unused item. *Display Item Special Price* There may be minor scratches on the outer box and the main unit. The OCD made in the early days used two Mosfets and one germanium diode. In order to reproduce the sound of that time, the OCD-Ge was created because Mike Fuller was able to obtain high-quality germanium diodes that satisfied his ears. Power: DC 9-18V power adapter (center negative) or 9V battery (manganese/alkaline) Size: 112cm (L) X 61cm (W) X 50cm (H) Weight: Approximately 410g
