Tano - Thanks for the comments. Glad you could get something out of it. Seems like there are others who like chunka-chunka.

It would, of course, be better termed "Country-Boogie-Blues-Even-8ths". Most of the boogie-blues tracks in BIAB have a swing feel. The "Country" form of this typically does not. I'm working on something now that is similar and have found an acoustic guitar track that works for it as well.

I'm working at 150 BPM and set it to Half-Time - and it's just what I've been looking for. So chaeck that out, as well.
