FULL-DRIVE 2 MOSFET with Overdrive and Boost functions. A famous overdrive pedal loved by professionals. It was mounted on an effects board, so there is some dirt from the Velcro, and the rubber cushions for the screws as shown in the 6th photo are missing, but there are no issues with its use. It produces a very clean sound. - Model Name: FULL-DRIVE 2 MOSFET - Color: Blue - Functions: Overdrive, Boost - Country of Manufacture: USA - Serial Number: 42404 Thank you for viewing.
