The C.G. Conn model 36H is one of the most popular Eb alto trombones available. It features a 7" yellow brass bell designed for excellent resonance and projection with a traditional wrap Bb section with a standard rotor valve adding facility to difficult passages. The .491"/.500' dual-bore handslide design provides an ease of response and open feel. The clear lacquer finish provides a subtle warmth to the overall sound. The C.G. Conn model 36H alto trombone with Bb attachment is designed for the player looking for a high performance alto trombone with slide positions in the same relative positions as a tenor trombone.
