I'm a big fan of the harp, but I don't play myself. I play in a band called Off The Wall (named after a Little Walter tune), with harp player Mike Fyles. Our influences include people like James Cotton, Rod Piazza, Rick Estrin (of Little Charlie and the Night Cats), Kim Wilson, George Smith, Little Walter, Walter Horton, William Clarke, James Harman and Sugar Blue.
Mike uses Huang and Hohner harps, and an Astatic bullet mic (repackaged by Hohner as the Blues Blaster). He also has a Shure Green Bullet mic, but prefers the Astatic in a live situation. The harp goes through a modified 50W Sound City valve amp.
