I'm glad to hear that you like the B3 much more than Boss .....since I just got the B3 2 days ago!
I haven't had much time to play with it.....it seems to me that a large portion of the presets are not very usable....but, I don't need a lot of patches, just a couple good ones. I will need to spend a bunch of time exploring all the possibilities, and tweaking the settings to get the patches I want.
I initially couldn't get the synth sounds I wanted, but I think I got some that are "good enough", and I bet with some more exploring and fine tuning I can figure some out that I like.
