I'm selling this because I'm retiring it after using it live. It shows considerable wear and tear, but it's still usable! I've confirmed that both the transmitter and receiver, which are in the box, are working. I'm selling this as junk since I haven't checked the operation, but I'll include two extra transmitters! Sorry if they're broken. I'll also include the shield, but the connection might be a little poor! This is a high-quality wireless guitar system that allows for free playing.
