Hmm-haven't tried DAG. I do DAD capo 1 (Em), DAD capo 4 (Am), DAC (Dm), and something weird for C minor (I'd have to look it up; would that be CGB?). I think I would have to restring for DAG, though. Ten-gauge strings flap too much when I tune them down that far. I should try it.

I've never heard a minor version of "Old Chisholm Trail", leeneia. Where'd you find it?
