Thanks, Dave. Yes, I think if I was into using BV's at all when solo, I think I'd rather record them and use an MP3, simply to get away from the block sound or having to tap dance them in and out in the right spot.
But I am still a bit unsure of how much I can do that simply can't be done by one person without breaking my audiences faith in whether I'm PLAYING it all or it's simply just karaoke. I try to keep my backings to bare rhythm section as much as possible, and play all the parts I can, but add in a bunch of harmonies, and I'm not sure if I'm crossing that believability line.
TBH, your voice is so good, I'm not sure I'd want ANYTHING to compete with it..!
