No need for a direct reply to this issue but after I installed this Beta (#2) a couple of days ago, every preset I tried (I tried about 10 of my own, Fenders, Marshalls etc and then about 10 factory presets across a range of amps) sounded like I had blown my monitors. Everything was affected so I thought the Adam's must have failed or maybe a faulty lead - maybe something else in my signal path. Anyway, I swapped out the lead and no difference and I thought before I started disassembling my studio rig I'd roll back to 4.03. I did and the problem vanished. Back to lush, rich tones on every preset I tried. Perhaps there was an issue with the #2 firmware install. Or perhaps there is an issue with my Axe FX3 and the new firmware.
Since I rolled back though I am having issues with the odd preset vanishing. Yes, one's I had previously made on 4.03. The preset title is there in Axe Presets but when you open it there is nothing there. I rebuild the preset and it seems to stay. Probably user error I suppose as I went to a new firmware and rolled back to the older one. I had made a backup of my presets on 4.03 and reloaded them but then I had different ones missing!
Just a report of one users experience. I have upgraded firmware via Fractal Bot loads of times with no issues. Sorry but I don't have more specifics than this. I'll sit tight and wait for the final firmware version and opt out of the Beta's for now.
