I noticed that when I first turn on the Axe Fx III that no matter what preset I'm on, it sounds rather brittle, almost ice-picky, but all I have to do is switch to another preset and then back to the original and the original now sounds much more mellow. Definitely get a significant change in sound without any parameter edits just by switching from one preset to another and then back again. Is there something going on here with some automatic parameter updates that I may have missed? Any thoughts are appreciated. Thanks
