The JP333 Rath is John Packer's Double Valve Bass Trombone and is suitable for musicians who are looking for a mid range/pro level instrument perfectly suited to orchestral playing, in a brass band section and also in a trombone section in a big band. The JP333 Bass Trombone has a broad and free sound, developed in collaboration with UK trombone guru Michael Rath. This JP Rath design combines a double in-line rotary valve with a modern open wrap style. The development of the JP333 Rath saw the instrument finely balanced, with the help of the counterweight, to ensure an excellent playing experience for musicians of all levels
