Rath John Packer Bass trombone

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

The JP333 Rath features a large  14.27mm (.562″) bore and a 241mm (9.5″) bell and is constructed from high grade brass throughout.

The instrument also features an exclusive Michael Rath design leadpipe which supports flexibility throughout the whole register. An extremely high level of craftsmanship is apparent throughout, as is to be expected with instruments that bare the Rath seal of approval.
