The Jiggs pBone was developed in the U.K. with the main goal of making music (playing trombone) accessible to young and old. Thanks to a lot of research and development, we finally managed to produce a plastic trombone that delivers a very good quality in terms of intonation, but also in terms of sound. The fiberglass composite tubes get better as the trombone is used more and more. The nozzle is specially designed for the pBone and has a small shaft that matches a standard medium bore, so you can also use normal small nozzles. The pBone has a water valve to allow excess moisture to drain away and a sliding lock.
