I upgraded to a B6 this week, after using a B1 Four X. To be fair, I never used the B1 to its full potential, but I was happy with what it could do. I upgraded to the B6 in large part because since I lost the sight in my right eye, I needed something that was easier to see, so the upgrade would have been worth it just for that.
However, this thing is amazing. 1 hour out of the box and I managed to set it all up for my needs without having to go anywhere near a computer. The effects are top notch, the modelled amps are pretty spot on, it’s got two inputs and a DI. I’ve read a lot about it being ‘only plastic’ (which is true), but there’s plastic and there’s plastic. It’s not made from yogurt pots so I’m not sure what you’d have to do to damage it. It’s sturdy, but I suppose if you abused it badly it’d break, but that’s true of anything.
I was initial hesitant, wondering if it would be that great an improvement on the B1. This just in: it definitely is.
