All of a sudden it sounds like my ultra is watered down. The digital effects seem to be there but the distortion in just no there. Almost sounds like when your battery is starting to go on active pick ups. Brown sound sounds like crap. Brit crunch is clean just to name a few. Sustain is all but gone. All patches seem problamatic. i upgraded from 10.5 to 11.0, tried differnt guitars, changed the cables, no luck. I had not modified or changed anything prior to this.
