Multi-function multi-effects processor, equipped with 6 buttons and 2 displays. - Model: G3n - Type: Multi-effects processor - Number of buttons: 6 - Number of displays: 2 - Connection terminals: Input/output terminals Thank you for viewing. I am selling this because I no longer need it. It has been used, but I think it is relatively clean. Please check the photos. The operation is good and it works normally. It is compact but very easy to use with its many foot switches. A DC cable is required for use. It is not included, so please prepare your own.
