The Hohner HOAC007 Harmonica Holder Large has the same traditional design as the Blues Harp Holder but with a larger adjustable brace, so as to accommodate a wider range of harmonica types. Diatonic, Chromatic, Tremolo and Octave harmonicas can all be used with the Harmonica Holder Large; the only Hohner harmonicas that are not suitable are the Orchestra models. A double-sided spring clamp secures your instrument in place, whilst the angle of the brace can be adjusted using the nuts at he join.
