Get Enhanced Playability And Tone With The XO Brass 1240L-T Professional Bass Trombone

The commanding power of this independent system, dual Thru-Flo™ valve model is prominent each time you perform. A large .571" bore bass trombone with 9.5" handcrafted bell creates a solid presence while still maintaining dynamic sensitivity and focus. A choice of either yellow brass or rose brass is available. Both bell options include soldered, oversized bell wire for increased sustain and sonic brilliance. The Thru-Flo valves provide unrestricted airflow and enhanced tonal clarity while offering superb intonation. The precision hand slide with brass outer tubes and chromed nickel inner tubes are hand-finished to ensure the smoothest possible operation. One sterling silver and two brass interchange-able mouthpipes allow the artist to custom tailor the XO Trombone's air column for the desired response.
