I Just installed version 5 beta #3 and went through my presets. They sound kind of lifeless and tinny, in a brittle way, compared to version 5 beta #2. So I A/B'd version 5 beta #2 with version 5 beta #3. There's something lacking in the fullness, tone quality and feel in beta 3. So I'm assuming some drastic EQing is needed.
It may be my ears, so I'm going to walk away for an hour or so and come back, as we had a long rehearsal this afternoon.
But even my band mates remarked about how killer and full my guitar sounded at rehearsal when I was on beta 2.
