So far what I’ve noticed are these (REV2.0 vs REV1.0):
- the screen is much sharper but less bright, and the colors are a bit more purple-ish,
- it has slightly more rounded edges,
- the knobs feel tighter,
- the power/VU LEDs are a bit deeper inside the case, or they are less bright,
- there’s a peace sign on the bottom next to the fcc/ce/‘don’t throw in the trash’ icons,
- the serial number is not only on the box, but also on the quickstart guide.
everything else works exactly the same as on the REV1.0.
