I am selling this item to organize my equipment. I believe it's rare to find a unit in such good condition. The micro BR 80 often has issues with the dial's responsiveness, but this unit has had the dial disassembled and cleaned, so there are no such problems. I have confirmed that it works with both batteries and an AC adapter. As it is a used item, there is some stickiness on the rubber parts due to hydrolysis. The items included are all shown in the photos. There is no original box. Thank you. The following is a product description: The BR-80 is the latest model of the MICRO BR, a compact, palm-sized device that allows for full-fledged music production. It features a stylish aluminum body and allows you to practice, record, and create songs just by connecting a guitar to the unit. The unit has three modes. The MTR mode offers 64V tracks and simultaneous playback of up to 8 tracks. You can create songs with intuitive operation. The eBand mode allows you to enjoy phrase training and sessions with your favorite songs. Furthermore, it is equipped with a Live Rec mode that allows stereo recording of phrase ideas and band practice. These functions work seamlessly together. You can read phrase ideas recorded in Live Rec mode in MTR mode to create songs, and practice the completed songs in eBand mode, realizing high performance and multi-functionality beyond the scope of a digital recorder. This is a must-have recorder for guitarists.
