YAMAHA THR10 guitar amplifier. I am selling this as I haven't used it in a long time. This listing is for the amplifier unit only; a USB cable, AC adapter, etc., are not included. I have confirmed that it powers on with batteries, but I have not tested the sound output or other functions. Please be aware of this. Recommended for display purposes or for those who can repair it themselves. Please purchase with the understanding that there will be no claims or returns.
