The Bach 36B trombone features an 8" one-piece hand-hammered yellow brass professional bell that offers a subtle brilliance with a complex color. The .525" medium-large bore combined with the traditional open F attachment offers outstanding clarity and balanced response with less resistance. The chrome plated nickel silver inner handslide tubes provide the ideal surface for smooth and quick handslide action. The clear lacquer finish adds a subtle warmth to the sound overall. The Bach Stradivarius 36B professional trombone is ideal for both symphonic and solo performance.
