Medium-large dual bore (0.525/0.547) intermediate horn with a traditional wrap F attachment and rotary valve. Features include an 8-5/8 inch rose brass bell, finger ring on the slide handle, brass outer slide tubes, chrome plated inner slide tubes, Conn6.5ALS mouthpiece and a woodshell case. Full warranty. In addition to being a great duel bore tenor in and of itself, the 52H is ideal for advancing players who want to make a smooth transition from a small bore to a larger symphonic trombone. With a medium-large dual bore and a convenient finger ring on theslide, the horn is a good match for players with smaller hands. The dual bore helps provide the larger sound needed in concert band & orchestra, while allowing for an acceptable "lead" sound in jazz ensembles. The 52H's use of a small shank mouthpiece and its 525 primary bore helps give the player greater flexibilty and a clearer (and easier) high range while requiring less air than a large bore model. A straight 547 bore slide can be added later to make this instrument a true symphony model, similar in many respects to the Conn 88H.
