The now-legendary and Boss FRV-1 '63 Fender Reverb. This pedal has been out of production for years and has achieved absolute cult status among guitarists and collectors worldwide. In collaboration with Fender, Boss used their COSM technology to digitally capture the exact, unique "drip" and characteristic sound of the original 1963 Fender tube reverb tank. With the Dwell, Tone, and Mix controls, you can instantly dial in anything from subtle vintage spaciousness to the ultimate, soaking-wet '60s surf-rock reverb. The pedal works perfectly and is in excellent condition.
