Professional Bb bass clarinet that is meticulously crafted by hand and provides a rich, warm sound extended to low C. It features a two-piece grenadilla body resistant to temperature and humidity fluctuations, with Boehm fingering system with 24 silver-plated nickel silver keys and 7 covered finger holes, as well as silver-plated nickel silver barrel and bell. The newly redesigned tone holes offer more stable intonation and improved playability. Each tone hole undercut is individually shaped for a beautifully balanced, remarkably responsive instrument. Metal inner tenon sleeves improve seal and tonal resonance. Other features include a fixed thumb rest, leather pads and an adjustable floor peg. An adjustable floor peg can be adjusted to proper playing position for players of different heights, while the redesigned posts bring more durability. A 4C mouthpiece with silver-plated cap and ligature and a carrying case are included.
