Hohner Big River Harp Harmonica (MS Series)
The Hohner Big River Harp is a diatonic harmonica recognised for its reliability and its association with the classic country-music sound. As part of Hohner’s Modular System (MS) series, it features interchangeable components that allow for extensive customisation and ease of maintenance.

Background and Design
The Hohner Big River Harp is designed as a dependable 'all-rounder' within the Hohner catalogue. Historically, harmonicas utilised wooden combs which, while offering a specific tone, were prone to swelling and cracking when exposed to moisture or temperature fluctuations. The Big River Harp addresses this by utilizing a black ABS plastic comb, ensuring the instrument remains stable and airtight regardless of the playing environment.
The Modular System (MS)
A defining feature of this model is its membership in the MS (Modular System) series. All components of MS harmonicas—including the cover plates, reed plates, and combs—are fully interchangeable. This allows players to fine-tune the instrument to their specific preferences. For example, a player who prefers the feel of the Big River Harp but desires a different resonance can swap the ABS comb for a wooden version from the Hohner Blues Harp MS model.

Ergonomics and Sound
The instrument is noted for its curved cover plates, which are ergonomically shaped to be comfortable during extended playing sessions. Sonically, it is engineered to produce a classic country-music style sound. The combination of the sturdy ABS comb and the specific cover plate geometry provides a clear, reliable projection that is well-suited for both beginners and touring professionals.
Market Position and Alternatives
At a typical price point of approximately £25, the Big River Harp sits as an accessible yet professional-grade option. While it shares the market with other diatonic models like the Fender Blues Deluxe, its primary advantage is the modularity of the Hohner MS ecosystem. For musicians seeking percussion or orchestral accompaniment, it is often paired with items such as Meinl Egg Maracas, Stagg Cowbells, or Sonor Orff Glockenspiels for a complete folk or country arrangement.
