Boss OD-2R Turbo Overdrive

In used but decent condition, works perfectly. 

The OD-2R has the same internal circuitry as the OD-2. Tests has shown that the R model has higher gain than the original but sounds very similar. The OD-2R's only new feature is the remote connector. It accepts and optional a latching footswitch, like the FS-5L, and can be used to switch the pedal's turbo mode on or off.
