The JP374 Sterling is JP's flagship 4 valve fully compensating professional level Bb Euphonium. Created in collaboration with Paul Riggett of Sterling Brass, the JP374 Sterling represents a fusion of professional level Sterling components and design with the affordability and durability normally associated with the JP brand. Widely respected as one of the leading designers and manufacturers of brass instruments in the UK, Paul previously worked as a production manager at Boosey & Hawkes before creating Sterling Musical Instruments in 1987. The JP374 Sterling Euphonium incorporates an exclusively designed trademark Sterling leadpipe.

The JP374 Sterling Bb Trigger Euphonium is constructed from high grade 80:20 brass throughout and features a 12" bell for superior sound projection. This trigger model offers players easier and more ergonomic tuning with the addition of a tuning slide trigger. As expected from an instrument of this level, the JP374 is fully compensating and includes a 3+1 bottom sprung valve system enabling an alternative fingering system. With high quality components and a pedigree many other makers cannot match, the JP374 Sterling offers players a professional level instrument at a highly affordable price.
