backfixer

adjusted the screws and played Tuesday night. It was great until toward the end of the set the tuning dropped while playing live again. I need to have this fixed. As I am not touring and using this constantly, there has to be a better fix, no? One of the screws does not tighten but the other is tight by the tuning modeling switch. Before I send this back is it possible there is a defect either in the switch or the original grounding. Don't see too many people mentioning this but it is a problem when playing live. When I go to the guitar pickups and then back to the modeling it clears itself up but i need reliability to trust the instrument. Love the guitar but this is getting old.

wow, thanks. I just adjusted these screws and the problem resolved. Wonder why when I sent this to line 6 the first time noone told me about this and I have not seen this suggestion anywhere else. I was planning to send this back in but I have a gig tuesday. Will see how it goes.

I purchased a JTV 69 a couple of years ago to be the one guitar needed for a gig. Mostly terrific and I had it professionally set up and use 09 string sets, I developed a problem where when I am using the les paul standard setting, on occasion, the guitar just drops a half step. Most noticible here and in the middle of a gig, it sucks. I then hit the modeling off button and it usually resets or the same when I remove the battery and then put it back. The upper tunings button usually begins to flash and I get a strange warbling tone when it does this. I had it in a local authorized shop who failed to fix it and then sent to line 6 in california last year where they had it working.until recently. Not sure what gives but guitar plays great unitl this
