So I'm considering getting a Zoom B3, since I was very happy when I got my G2.1u, and I would like something for bass that has some more features. My question is this: how are the built-in compression and looping functions? Zoom makes good effects that do what they need to most of the time, but I want to know how these two effects on the B3 compare to a standalone compressor pedal or a loop unit. I'm more concerned with the compressor, since that's the salt of effects for bass, and the compressor on my G2.1u felt very limited. Anyone have experience they can share? I know that the effects in a multi unit can't compare to getting a really good standalone, but I want to know how they compare, if they're quite good or if they're cheap crap. I have a lot of faith in Zoom, their effects sounded very organic for a digital multi unit, but I want to know if those features on the B3 are strong it weak points of the unit. Thanks!
