Good morning, long time Axe Fx owner/user here. Last night I noticed a sudden change in all of my overdriven tones, with and without drive blocks. Marshall, Atomic, Ero Blue, etc. I have what I can only describe as an oscillating distorted overtone in single notes and chords. Additionally, there is a distorted "chirp like" sound a moment after I hit a single note, almost a subtle "thump." I have tried multiple cables, a wireless to move further away from the unit, and multiple guitars. PRS, Fender and Gibson. I updated to 15.01 when it was first made available and have had no issues. I checked my input levels too and the problem is still there when turning down. I am using Yamaha HS8 monitors and regular music sounds fine through them. The problem seems more pronounced in the lower three strings, but is still noticeable on the others.
I don't have any new appliances, lights, phones, modems (my modem is in another room), or any other new addition to my home. I have tried using all inputs and outputs and have checked with headphones. I unplugged my expression pedals and even tried a new preset with amp and cab only. I tried rolling back my firmware, 14.06 wouldn't produce any sound at all, and then re-installed 15.01. No luck with anything I have tried. I also tried plugging into a different outlet. Any ideas would be greatly appreciated. The answer is probably obvious, but I'm blanking now. As always, thank you.
