John Packer Rath Single Trigger Bass Trombone

The JP233 Rath is John Packer's B^b/F Single Valve Bass Trombone and is suitable for musicians who are looking for a single trigger bass trombone.

Lighter than the double trigger bass trombone, but with an equally broad sound.

Developed in collaboration with UK trombone guru Michael Rath. This JP Rath design combines the simplicity of a single in-line rotary valve with a modern open wrap style. The development of the JP233 Rath saw the instrument finely balanced to ensure an excellent playing experience for musicians of all levels.
