Enjoy playing guitar freely with this digital wireless system. Operation confirmed. The transmitter and guitar are basically connected using a cable, but a phone-to-phone adapter is also included so you can connect directly to the guitar. Also, the cable is a 60cm Classic Pro cable. The 9V battery snap for power is shown in the photo, and if you wish, I will include this as well. - Brand: LINE 6 - Model: Relay G30 - Included items: Transmitter, receiver, power adapter (BOSS PSA-100) - Function: Digital wireless system - Number of channels: 6 channels Thank you for looking.
