I've thrown this one out before, but I REALLY love it, so what the hell....

Al Cromwell's A9th.

Put your ring finger on the 5th string fourth fret, and your index finger on the 4th string 2nd fret. Strum all 6 strings. A HUGE A chord. use it occasionally as a substitute for A7th or in blues in E. (as a replacement for A7th)

Al Cromwell was one of the most neglected musicians who ever lived. A Black Canadian with a smooth guitar style, great voice and VERY suspicious of recording Company executives! He passed on much too early.
