I think it was @jimmy23cricket that had the B3n, not me. Used to have a B3 a long time ago (well, it feels a long time ago!).
Definitely preferred the Line6 devices over the Zoom, replaced the B3 with a PodXT Live, then the HD500x, now the POD Go.
The only criticism of the POD Go is that it is limited, small number of "free" effects blocks, no parallel signal paths, no DI XLR, limited number of bass-specific effects, etc. None of these are deal breakers IMO, and I still think it's a great piece of kit for the bass player.
I plug it into the "Effects Return" on my amp, so the signal is straight into the power amp section.
