The development of the daCarbo trombone was supported by test reports of well-known musicians through all musical stiles. The principles of engineering in the vibration's behavior with carbon fiber composites were successfully transferred from daCarbo trumpets to the trombones. As with daCarbo trumpets, this trombone is incredibly easy to play, while producing the highest quality of sound. It allows excellent articulation, flexibility, and musical ideas to flow, since the horn can be played most easily, using less energy. The carbon fiber outer slide can never bend or dent and is manufactured much straighter than a brass slide trombone. As a result, the gap between the outer and inner slide can be held at a minimum, allowing only enough space for lubricant. This new technology enhances the sound, speed, and quality of the instrument. Furthermore, the new carbon fiber outer slide is extremely light, giving you the utmost comfort in precision of sound quality and performance.
