HANDS FREE HARMONICA ON YOUR VOCAL MICROPHONE - Uses a powerful magnet to secure the harp. Works with all standard harps (even plastic via an included metal strip). Clamps on to most any mic stand. 5-way adjustment; telescopes to 16 inches. Easily swings down and out of the way when not in use. Optimized magnetic strength allows for quick and easy harmonica changes. Excellent for guitar players and for singers -- no annoying neck rack to deal with. 2013 NAMM Best-In-Show award winner.
