The JP257 is an ideal choice for an advanced player looking to expand their repertoire for the later grades or at university level – perfect for tackling the popular Haydn, Hummel and Neruda trumpet concertos.
Designed in collaboration with Dr Richard Smith of Smith-Watkins, the JP257SW offers the standard of intonation and playability that would be expected of professional models. Made from High Grade Brass and featuring monel valves and a specially designed Smith-Watkins reverse leadpipe, the JP257SW is very resonant with a bold, rich sound. The instrument can easily and efficiently change pitch between D and Eb by simply swapping the main tuning and 3 valve slides with the extra 4 supplied.
