I think I got in on the ground floor with BIAB when it first came out years ago. I’ve upgraded with each new version and plan to order the new 2015 release. Using it for gigs on guitar for the longest, I finally switched to arrangers some time back. Solo guitar work and vocals with BIAB is fine. But, the guitar on every song, every solo, became exhausting and somewhat boring. To me, the richness of an arranger’s sound, the endless supply of lead voices for soloing, allows for a greater variety of sounds and a more interesting presentation for the gigs I play. But, I’ll play a guitar gig with BIAB on a moment’s notice, if that’s what’s called for and if it fits the situation best. I guess I could try using BIAB with my arranger. Never thought about that.
