XO professional trumpet features include a traditional yellow brass body available in bright silver-plate or high-gloss clear lacquer finishes. Handcrafted bells are provided in yellow brass for clear quality of tone.

The 1600i features a .453" bore, yellow brass body and a 4.8" handcrafted B1 bell with heavy bead and enhanced bell ferrule. The combination of these two features creates an instrument with exceptional dispersion, clarity, and tone. This model also features a reverse leadpipe and professional two-piece valve casing with nickel silver balusters and includes stainless steel valves and a vertical third valve stop. The 1600i is available in a clear lacquered (1600i) or silver-plated (1600is) finish. Players can customize their horn with the pearl inlaid or metal finger buttons, regular or light action springs, and standard or heavy weight bottom valve caps. Also included are the special XO Nodal Stabilizers that reduce the gaps that normally contribute to turbulence and excessive resistance.

Each XO trumpet is built around a traditional two-piece valve casing with nickel silver balusters. By offering a wide selection of bell materials and leadpipe options as well as standard trim package incorporating both round and D-shaped tuning slides, pearl and smooth valve caps and two levels of valve springs, these models can be customized to meet the professional's performance needs.
