The Fender G-DEC 3 Thirty includes a stereo Line Level Output in the form of two ¼ inch TRS (Tip Ring Sleeve) jacks, for interfacing with other equipment such as mixers and audio interfaces. The output level for these can be controlled from the Line Level screen in the UTIL menu. By default, the output level is set to 10 (the max). To enter Utility mode, simply hold the EXIT button on the front of the G-DEC 3 for a few seconds.
