Final price reduction! I received this from a fellow musician, but I'm selling it because I have too many amps. I received it in almost new condition, and I haven't used it much either. It has been stored in a dark place. It's in good condition, with only a scratch on the battery cover. Before listing, I connected it with an adapter and checked it thoroughly at a volume suitable for home use, and there were no problems. It's 10W, but I think it's sufficient for home use. It can also be powered by 8 AA batteries. The panel on the back has not been checked. If you don't need the adapter, I will discount it by 1000 yen! Please comment if you'd like that. Please feel free to ask about combined purchases! Immediate purchase is welcome!
