Amazing repair work.
I sent my Helix to Line 6 So. Cal. on a RMA. They received it early on the 12th of August and I just got it back this morning around 9:30am Pacific. I then uploaded 25 IRs and 4 User setlists; not all the setlists are at 100% so maybe 120 presets all together. And I did install the setlists not the individual presets just for the heck of it. Then I overwrote several of the presets with other presets as a test.
Before I sent it in I could recreate my issue repeatedly. After stress testing it and doing everything I could to recreate the issue there was not one hiccup other then the rebuilding presets the first time I restarted the unit after loading my presets. Other than that I have had several hours of trouble free performance.
But there is more! The reverb and echo FX blocks I use are ... "WOW" ... crystal, more pronounced, and almost sound like higher then high fidelity components got installed. I am now toning down my reverb and echo FX blocks as well as reducing the gain to below 0.0 on my normal global EQ setting.
Playing a Fair this Thursday. Can't wait
Thank you to Line 6 repair
