Hi David
Really nice vibe going on here, I agree with some of the other comments posted here, you Gibson would really benefit from mic'ing it up rather than DI.
Personally if you put Vox on it, maybe just a couple of lines, something like "Don't have time to do much", then pause "See you 'round sometime", that's all, maybe spoken. I hear a slide acoustic solo in there somewhere...
MIDI is such a mystical place, I avoided it for years, but then I dived in an it's kinda useful now. Good luck.
