From 1966 to 1968, Mosrite produced two distinct fuzz circuits - one outfitted with silicon transistors, the other with germanium parts. Of the two, the germanium version is by far the most rare, with original designer and Mosrite employee Ed Sanner estimating that around 250 ever made it out the door. In that final year of production, Mosrite shifted exclusively to silicon parts, making germanium components a thing of the past. This pedal uses two NOS PNP germanium semiconductors. The initial release is limited to 300 pieces! In stock now at Twin Town Guitars! • MFSKU FUZZRITE GE • UPC 853710004772
