The Jiggs pBone was developed in the U.K. with the main aim to make music (playing the trombone) accessible to young and old. Thanks to a lot of research and development, we eventually succeeded in manufacturing a plastic trombone that delivers an incredibly good quality in terms of intonation, but also sound. The glass fiber composite tubes get better and better as the trombone is used. The mouthpiece is specially designed for the pBone and has a small shaft that matches a standard medium bore, so you can also use normal small mouthpieces. The pBone has a water valve to drain excess moisture and a sliding lock.
