All four of the non-slip rubber feet on the bottom are missing. It's reasonably old and has some dirt, which I tried to wipe off with alcohol, but there were some spots I couldn't get clean. The inside hasn't been cleaned. The BOSS FV-50L is a high-quality volume pedal for guitar and bass. - Model Name: FV-50L - Brand: BOSS - Connections: Input jack, Output jack - Colors: Blue, Black - Type: Pedal Thank you for looking.
