Available for immediate purchase! [Complete with all accessories - box and batteries included] AKG WMS40 MINI (JP1) This is a wireless system for musical instruments such as electric guitars and basses. I purchased it about 5 years ago and have used it a few times. Operation has been confirmed. The frequency is in the B band, so it is less likely to interfere with Wi-Fi and Bluetooth, and it is also resistant to obstructions. The receiver, transmitter (with batteries), instrument connection cable, and AC adapter are all included. The transmitter has some scratches, but overall, the condition is good. The box has dents, scratches, and discoloration, but some of these were present when I purchased it, so please understand.
