This comes with a Gator Tenor Sax case, and a Vandoren V16 Metal Mouthpiece (T6 Large Chamber) with ligature with interchangeable pressure plates and mouthpiece cap. Here is the description of the Sonus from the Kessler Website.
Our new Kessler Custom Sonus tenor sax is named after its most impressive feature, its sound! They are designed for the player who wants the larger, broader style tone found from early American vintage horns as well as modern Keilwerth saxes, but also wants modern intonation, responsiveness, mechanics and materials. Willing to meet in Powell, Columbus, or most areas in Ohio.
