The fast, free blowing CL2000 valve and open wrap F section enhances the traditional 88H design, making for a truly "straight-thru" open horn, with the best possible response in the trigger register. This model features Conn's "Generation II" bell, which uses somewhat thicker brass than that of the mid-20th Century Elkhart models. The result is an instrument comparable in response and tone color to that of other modern makers' symphonic models.
