Unique benefits

The JP138 is John Packer's rotary valve Bb/C trombone featuring a short slide design enabling younger players to achieve the whole range of notes via its ascending C rotary valve. This helps players with smaller hands to achieve the 6th an 7th slide positions of a regular Bb trombone. The JP138 also features an ergonomic thumb rest/trigger helping players to get acquainted with holding and playing a trombone.

Bought one last year, for my 7 year old son. Really good tbone, punchy, easy to play, not tiny sound like the yamaha 350c my other boy used to play at the same age. Many other parents & teachers interested in that jp138 model, outstanding ratio quality/price.
