Hey Guys ..... Question: What is the starting serial number or dates for Helix, where the scribble strips were corrected. Here's my situation and the reason for asking ... I received my Helix on Dec.21, 2016 and by Jan. 19, 2017, I started noticing broad black lines developing on the scribble strips.(Common problem based on my search results) I created a ticket (Recommended by several users with the same problem here on the forum) on Jan 27, 2017 and have not heard anything from Line6 to date. Now while I'm the first to admit, that this may be just a cosmetic issue\fault that one can learn to live with. Still, if there are underlying issues\problems and this is just the beginning stage of a more involved fault, then it becomes a major concern. I have a 45-day return policy, of which I am fast approaching my cut-off date. I mention this because I can possibly return the faulty unit for a new one, but I don't want to revisit this issue with a new unit. (Kinda defeats the purpose of returning it) That stated, I'm hoping someone can share the dates and or serial numbers of newer units where this issue was addressed completely. Thank you in advance!!!
