Hohner Big River Harp ProPack Harmonica Keys of C, G & A

Modular construction places the Big River Harp ProPack in Hohner's MS series, where comb, reed plates, and covers swap between models for custom configurations. This three-pack includes harmonicas in the keys of C, G, and A – the core keys for blues, folk, and country styles – with each harp built around a durable plastic comb that holds tuning stability across varying humidity and temperature. Curved cover plates improve grip and control during bends and overblows, while TORX screws replace traditional fasteners for more reliable plate alignment and easier tear-down when cleaning or adjusting reeds.

The plastic comb resists swelling and warping that can plague wood designs in Australian climates, maintaining consistent air-tightness between the reed plates. Each harmonica ships in a snapcase that protects the instrument between gigs without the bulk of vintage-style clamshell boxes. The MS-series standardisation means players can mix reed plate tunings, comb materials, and cover designs across the Hohner range as technique develops. All three keys use the 10-hole diatonic layout with 20 reeds tuned to Richter configuration, providing the full two-and-a-half octave range required for position playing and cross-harp techniques in blues and roots music.
