This is a Blackstar 15W amplifier. I connected my guitar and confirmed that it produces sound. This is a used item, so there are signs of use such as scratches, peeling, and dullness. The only included accessory is the power cable. The box, instruction manual, and shield cable are not included. If you have any questions, please ask before purchasing.
