Broken LT Expression Pedal in Helix Posted July 30, 2019 Line 6 I BELIEVE is offering free extended warranties on LTs that are registered. I would ask them---they have been great with me. Replaced the second faulty LT with the bigger Helix. Thanks Line 6. With both LTs I had, the pedal became increasingly tight until it snapped. If you are not experiencing that you are probably ok.
