Large bore (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, Conn 6.5ALS mouthpieceand a woodshell case. Full warranty. The 52HL is similar to the original 52H except that it comes with a large bore slide instead of the 52H's medium-large dual bore model. With the large bore slide, the 52HL thus becomes a great choice for advancing players who want an affordable, well-built American made large bore horn, without sacrificing tone quality, eveness of scale or durability. The horn is thus similar in many respects to Conn's top of the line 88H, though at a fraction of the cost.
