The .575" bore possesses a uniquely compact, centered and focused voice. The softest pianissimo can be produced almost effortlessly and maintains a uniform, homogenous sound over the entire range and at all dynamic levels. Accurate intonation, particularly the treacherous throat E to high B and throat F to high C intervals, results from detailed bore proportions, precise reaming, and exact tone hole size, position, and undercutting. The Signature’s modern, streamline design contributes to its quick response. Utilizing durable power-forged nickel silver keys, additional reinforcing of the exposed right-hand alternate keys increases their strength. Steel rings mounted on half of the thickness of the tenons ensure the wood stays in contact from barrel to upper and lower joints. All Signature clarinet outfits, whether single or double, include a deluxe leather-covered, French Style case.
