This Boss DR-01S Rhythm Partner is in Very Good condition with light scratching around the body. The battery compartment had corrosion; it has been cleaned, and the contacts have been tested and confirmed working on battery power, though slight remaining corrosion is still visible. Designed as an “organic” rhythm companion for acoustic players, the DR-01S pairs simple, musical grooves and percussion tones with a friendly interface and an onboard speaker for easy practice, songwriting, and small jam sessions.
