No new sounds but something useful for those of us that just want to grab an amp and play: a "Default Amps" bank for GR3 - nothing but the 12 amps with their default cabinets. The default cabinet module has two microphones so there's a second set of presets for use on a stereo track with a dual cabinet setup, one panned hard left with mic A and the other panned hard right with mic B. The amp settings and cabinet dry/air settings are default.

Here's the list of presets:
