Roland BTM-1 This is a speaker that combines a Bluetooth speaker and a guitar amplifier. If you have a guitar, you can use it as a mini-amp. It also functions as a Bluetooth speaker, so you can play music from your smartphone. I bought it new around 2022 along with an electric guitar, but I didn't improve at guitar and gave up, so I've been storing it at home. There are some scratches and stains, so please check the photos. Operation has been confirmed. Only the main unit and the box are included, so I am open to price negotiations. Please check the website for operating instructions. I would like to sell it to someone who needs it. New purchase price: 19,800 yen #GuitarAmp #Guitar #Roland #BluetoothSpeaker
