Was on Axe echange loading a few presets, and had a couple come up with no sound, so i reloaded another that I liked stored it. Had a couple where I had to load cab IR's as well, everyhting seemed fine. Then I went back to one of my favorite presets that I had edited and stored, and it was replaced by one of the presets that I loaded up that had no sound? I was no where near that preset when I was laoding the new ones just so I wouldnt even sniff the chance of screwing it up. Anyone ever have this happen, and why does it haappen? Thanks everyone.
