Hohner Pro Harp Harmonica in the Key of Eb

Black lacquered cover plates without side vents give the Hohner Pro Harp its signature rock–ready aesthetic and tonal focus. Often called the Rock Harp, this diatonic harmonica in the key of Eb combines the plastic comb from Hohner's Big River model with the cover plate geometry of the Blues Harp, creating a robust instrument that holds its own alongside guitar, bass and drums. The modular MS–series construction means reed plates, combs and covers can be swapped with other compatible Hohner models, allowing players to customise tone and response.

The plastic comb resists changes in temperature and humidity that cause wooden combs to swell or crack, maintaining consistent air–tightness across all climates. Torx screws secure the cover plates and reed assembly, providing stability during aggressive playing while simplifying disassembly for cleaning and maintenance. The all–black finish extends across the entire instrument, reinforcing the stage–focused design. A hard plastic snapcase protects the harp between gigs without adding bulk to a gig bag.

Hohner designed the Pro Harp to complement electric instruments rather than acoustic contexts, with the sealed cover plates directing airflow for projection and volume. The Eb tuning places this model a semitone below E, useful for matching horn sections or transposing songs down from standard keys. Because it shares the MS–series platform with the Marine Band, Special 20 and other Hohner diatonic models, players can mix components to dial in specific tonal characteristics or replace worn parts without replacing the entire instrument.
