JP332 Rath ProTenor Trombone with F Attachment,.547”


Brand John Packer

The JP332 RATH represents John Packer's flagship Bb/F large bore tenor trombone designed and manufactured in collaboration with Michael Rath, one of the UK's leading trombone specialists. With an unparallelled level of craftsmanship, the JP332 RATH is the result of many years of development and features some exclusive components that players won't find on other instruments. A custom designed Rath leadpipe was created especially for the JP332 RATH which gives excellent response in all registers whilst retaining support for inexperienced players. The instrument also features an ergonomic thumb lever which is easy to adjust for smaller hands. 

The JP RATH range of trombones have generated a lot of positive comments throughout the industry and are now in demand across the globe. They are characterised by a professional standard of workmanship and a high level of performance. Often compared with professional models, they compare very favorably with instrument from some of the top makers. The JP332 RATH features a large bore (.547") providing players power and projection in symphonic works whilst it's 8.5" bell gives even greater sound projection that it's smaller brother, the JP331 RATH. High Grade 80:20 brass is used in construction throughout.

Simon Cowen - principal trombone of the Royal Liverpool Philharmonic Orchestra
It was very clear from first blowing the JP3320RATH trombone that it had a very clear, vibrant and open sound. An exciting colour of sounds throughout the register and a real and rare treat being so open in the trigger register.

I trialled this trombone in the orchestra in various concerts and recordings from Shostakovich to Brahms and the projection was very easily achievable due to the responsiveness of the instrument. I also played the trombone in the brass band and it was here I realised the versatility of the instrument throughout all registers and dynamics.

The most important value is that the JP3320RATH is not out of place amongst other model trombones within the section, being very easy to blend with.

A very fine model of trombone, perfect for players in whatever field of ensemble. An extremely true and fine blowing trombone suitable for all.
