Re: Basic Blues chord progression exercises
Just to find something -anything- quickly, there's no reason to limit yourself to "BLUES progressions FOR MANDOLIN". A progression is a progression, and a set of chords can be applied to any instrument.
I'm no expert, but classic rock, rockabilly, and even folk are rife with 12-bar blues. And it's the 16-bar blues by which Monroe the blue in bluegrass (uhmm, besides the groundcover in Kentucky).
Be aware that the "highly extended" jazz chords can often be substituted with the underlying major or minor chord, maybe with just the 7th added. And yes, a lot of jazz simply follows the IIm-V7-I progression, which in the key of C would be Dm, G7, & C. They're often prettied up w/ extra notes (maybe Dm7, CM7), but just drop the D note from the Dm7, and the extra ones elsewhere, and you have the world's most basic set of F, G, & C.
This is far from a comprehensive or even specific answer, but it should help widen your search.
