- Model Name: THR5A - Included: Power cable, Instruction manual Thank you for viewing. I am selling this item to declutter. It's an amplifier for acoustic guitars and ukuleles. It can also be powered by eight AA batteries. When playing in a band, I preferred using batteries because extension cords can make the area around your feet unstable. The exterior has no noticeable scratches. I think it's in beautiful condition. There are no issues with the functionality either. * I am not considering price reductions. I am looking forward to selling to someone who will be happy with their purchase. * No claims and no returns, please.
