YAMAHA Custom Xeno Series N-94 Custom Special Order Tenor Trombone Slide for Large Bore [Specifications] Slide Tubes: Nickel Silver, Lightweight Slide Crook: Gold Brass This is a custom-made slide based on the N-94 (lightweight nickel silver + yellow brass crook), a standard option for Xeno trombones. It features a wide crook made of gold brass, which is not available in the catalog. The key difference is the bore size. While the standard Xeno wide slide crook has the large bore of a bass trombone, this one has a bore slightly larger than a tenor trombone. It has specifications similar to a Shires TW47. This slide allows you to achieve a soloist-style sound like a German trombone, and it's easy to handle. Xeno trombones have a wide variety of slide options, but this one was created to address specifications that were not quite available. It's effective to use it in different ways, like Ian Bousfield. Don't miss this opportunity. Although both the slide body and parts are new, there are some areas where the lacquer has been chipped during disassembly and assembly.
