This is the BOSS RV-5. I used it for live performances and in the studio for about a year, and for about three years after that, I only used it occasionally at home, mostly storing it in an effects pedal case. There are a few scratches on the side, but the front is clean. There are no issues with its operation. The box and instruction manual are not included.
