I had a similar experience and finally entered a support ticket. This is a hardware issue that occurs occasionally and if you fill out a ticket, Line 6 will take good care of you-itâ€™s a warranty repair. I sent my Helix in 7 days ago and they replaced all of the foot switches and according to UPS Tracking it will be delivered Monday! I got it in November â€˜15 so the 2 year warranty was about to expire...but I have a feeling they would have covered it anyway. I continue to read stories of how Line 6 has gone above and beyond when it comes to customer service.
I waited a long time to fill out a ticket; I wasnâ€™t sure what the problem was because it was so intermittent, and I thought I was doing something wrong when building presets...I had a few gigs that werenâ€™t much fun because I hadnâ€™t figured out what the problem was. I even got another Helix as a backup (I was going to do that anyway) but Iâ€™m happy with how things turned out. Fill out a support ticket, or call and talk to someone-they will get you squared away!
