Traditional harmonicas are designed for optimal performance with some compromises to facilitate industrial production. The Polle concept, however, is developed strictly from the perspective of the performer, with no sacrifices in the musical or technical qualities of the instrument.
The Polle Concert Harmonica is a chromatic harmonica, combining craftmanship, sophisticated technology and manual finish to ensure lasting quality and performance. Tommy Reilly described the interior of the instrument as a work of art, and praised the Polle Concert Harmonica as the Rolls-Royce of all harmonicas.
The mouthpiece and the covers are highly significant to the comfort of use. The Polle concept solves the traditional issues with these parts by using carefully selected materials and applying special design elements.
The silver version mouthpiece is plated with gold to avoid oxidation, while a titanium version mouthpiece comes without plating.
The holes are designed to maximise the comfort of the performer.
Two delicate grooves running longitudinally at both sides of the mouthpiece collect saliva that lubricates the lips to reduce the friction.
There will be no galvanic sensations to disturb the performer, as the screws for the mouthpiece are made of titanium.
The covers are of a closed design, and mounted air tight against the reed plates. They are made from 925 sterling silver, which adds a warm timbre to the tone. The silver is also easily heated by the hands and feels very comfortable against the lips.
As a continuation of the mouthpiece, several delicate grooves run longitudinally at the covers to further enhance the lubricating effect of the saliva.
The covers may be engraved with decorations to the request of the client.
The interior of the instrument consists of the unique Polle body, the special Polle slide system, and in standard versions; a set of high-quality Hohner reed plates modified by Polle. These vital components are described separately.
