Check the listing for details. Hohner Xpression Chromatic Harmonica. Condition: New. Listed at 245.49 USD. Chromatic Xpression Unleashed! Xpression chromatic harmonicas by Hohner offer musical dependability with a classic sound and modern feel. Xpression harmonicas use only the finest brass reeds — the defining element of world-class harmonicas for more than a century. Reeds are housed in a sleek stainless steel chassis that prioritizes air tightness and oozes with modern design, including sleek corners built for comfort and control. With prowess like that, seasoned pros will feel right at home, and intermediates can go beyond the diatonic box to explore the 3-octave chromatic range. Inside, a plastic comb houses the reeds. Since they are climate-resistant, many pros have come to prefer the reliable, consistent sound of a plastic comb over old-school materials.
