So i've done some extensive research on this topic, but can't seem to find a straight answer as to proper settings for this to work. All I'm trying to do is plug my headphones into my POD X3 and play guitar. For some reason, no matter what I do, I can't get my guitar to come out of my headphones. The tuner works fine, the firmware is up to date and I don't need to flash my unit. I get a pop when unplugging and plugging in the headphones so I know they work just fine. Would someone be so kind as to tell me the exact procedure to get this to work? Even the Line 6 manual for the X3 doesn't really say how to set it up. I'm not trying to record, I'm not trying to run through a half stack or a sound board, I just want to play guitar in my headphones. Thanks for any help! Jon
