Common Questions About the C.G. Conn 10DY

How does the Conn 10DY differ from the Conn 8D?

The 10DY uses an all-yellow-brass Geyer-style wrap with a 12-inch small-throat bell. The 8D uses a Kruspe-style wrap, nickel-silver construction, and a larger 12.25-inch bell. These designs provide different response and tonal concepts rather than a simple difference in quality.

Does the Conn 10DY have a fixed bell?

Yes. The 10DY has a fixed bell. Conn designates the detachable-bell version as the 10DYS.
