The Live 3 is more user friendly for one. It has 10 knobs on the front and 3 switches (for foot operation) that are understandable. The harmony presets are easy to edit and resave. It sounds better than the Live 2 (to me) and doesn't glitch as much. They've added adjustable warmth and compression knobs, pitch correction, EQ, harmony mix, and a humanize feature. It may not be for everyone. But when you're working solo, you continually look for additions or improvements to your sound---at least I do. I'm investigating now the new Roland BA-330 stereo amplifier, since BIAB sounds much better on stereo playback rather than mono, such as through the BOSE setup that I've been using. Wonder if anyone has seen or heard this new Roland?
