Lowell, you don't know Jack Schmidt about guitar playing. Sure- most Country and Bluegrass are 1-4-5 progressions, but the circle of fifths is NOT a ring of Jack Daniels bottles around the circumference of a poker table. I've been playing serious for 10 years, and if you bothered to read my posts here- a 1965 Martin D-28, a 1968 Martin HD-28 with a Fishman pickup and a Martin Custom shop HD-35 circa 1992 ain't "pawn shop flat-tops", ditto my Paul Reed Smith and my older National metal resonator in open D (that's Dad-Fad dumbass) actually F is F sharp, but why should I throw my SP medium gauge strings before swine-You want a guitar match, go out to Winfield Kansas in Sept. and see how you hold up-I know my chops, still to your friggin trailer park tractor session with your 1-4-5 chords, maybe you'll get somewhere, but I seriously doubt it.
