Suzuki SA-50 multi channel amplifier. Can be used for piano, guitar, playing music, or vocals. It was always used as a guitar amp in our house, but we bought a new modeling amp so out with the old. It sounds great and work awesome. There is an 8.5 inch speaker and a smaller 4 inch speaker. The original manual and receipt are also included. Please message or text me with any questions. Thanks for looking.
