Overview

The Hohner Pro Harp MS is a professional-grade diatonic harmonica that forms part of Hohner's Modular System (MS) series. Specifically tuned to the key of F, this instrument is distinguished by its 'Stealth' aesthetic, featuring matte black coated cover plates. Unlike traditional harmonicas with side vents, the Pro Harp utilises closed covers to direct all sound forward, which is particularly advantageous for players who use microphones.

The Modular System (MS)

A primary feature of the Pro Harp is its compatibility with the Hohner Modular System. This design philosophy allows all components—the comb, reed plates, and cover plates—to be interchangeable across the MS range. For example, a player can swap the standard ABS comb for a wooden Blues Harp comb or an aluminium Meisterklasse comb. Additionally, the covers can be replaced with the curved ergonomic plates found on the Big River Harp model to suit specific grip preferences.

Construction and Durability

The Pro Harp is built for longevity in varying environments. The comb is manufactured from Acrylonitrile Butadiene Styrene (ABS), a high-grade plastic that is immune to the swelling and cracking often associated with traditional pearwood combs. This makes the instrument highly stable in different humidity levels. The black cover plates are not only aesthetic but are designed without side vents, allowing the player to cup the instrument tightly against a microphone for a concentrated, powerful output.

Sound Character and Performance

In the key of F, the Pro Harp provides a bright and punchy tone suitable for lead roles. Because the sound is directed solely through the rear of the instrument, it offers a focused projection. The airtight construction provided by the plastic comb ensures a fast response, making it easier for players to execute techniques like note bending and overblows compared to more traditional, vented models.

Comparative Analysis

Within the Hohner ecosystem, the Pro Harp sits as a modern alternative to the Fender Blues Deluxe or the wood-combed Hohner Marine Band. While the Fender Blues Deluxe offers a classic aesthetic, the Pro Harp focuses on modern materials and customisation. Compared to percussion-focused gear like the Meinl Spin Spark Shaker or Stagg Cowbells, the Pro Harp serves as a melodic lead instrument. Its closed covers provide a distinct sonic difference from the Big River Harp, which shares the MS architecture but uses different plate shapes.

Frequently asked questions

What is the benefit of the black cover plates?
Beyond their stylish appearance, these plates have no side vents. This design ensures that all sound is projected forward towards the audience or into a microphone.
Will the comb on the Pro Harp swell over time?
No, the Pro Harp uses an ABS plastic comb. Unlike wooden combs, ABS does not absorb moisture and will not swell or crack in different humidity levels.
Can I swap the comb on this harmonica?
Yes, because it is an MS model, you can switch the ABS comb for a wooden one from a Blues Harp or a premium aluminium one from a Meisterklasse.
Is the Pro Harp suitable for amplified playing?
Yes, the lack of side vents makes it easier to achieve a tight seal when cupping the harmonica against a microphone, resulting in a powerful amplified sound.
What key is this specific model tuned to?
This specific model is tuned to the key of F Major. It is one of several keys available in the Pro Harp product line.
How does the Pro Harp compare to the Big River Harp?
Both belong to the MS series, but the Pro Harp features black non-vented covers. The Big River Harp uses different curved covers, though they can be swapped between the two.
What is the typical price for a Hohner Pro Harp MS?
The typical price for this model is approximately £39, placing it in the mid-to-high professional bracket for diatonic harmonicas.
Is the Pro Harp a diatonic or chromatic harmonica?
The Pro Harp is a 10-hole diatonic harmonica. It is designed primarily for blues, rock, and country styles rather than the button-operated chromatic style like the Sonor NG31.
Can I use different cover plates on the Pro Harp?
Yes, as part of the MS system, you can install different covers, such as the curved plates from a Big River Harp, to change the grip and feel of the instrument.
Who is the Hohner Pro Harp MS best suited for?
It is ideal for performers who need a durable, humidity-resistant instrument for live gigging, particularly those who play with a microphone and want a modern look.
Does the Pro Harp require special maintenance?
Maintenance is simplified by the ABS comb, which requires less care than wood. However, regular cleaning of the reed plates and covers is recommended to maintain hygiene and performance.
