The JP133LR Bb/F Is John Packer's large bore tenor trombone perfect for school ensembles, training bands and for those players who require a reliable Bb/F trombone but can't justify the cost of a more expensive instrument. Well respected in developing high performing but affordable instruments, John Packer's have equipped the JP133LR with a rose brass bell giving it a fullness and maturity in tone that is usually not found at this level.


The JP133LR Bb/F large bore tenor trombone boasts an 8.5" bell and a large shank .547' bore. A bell ring provides a robust structure and a rose brass bell ensures a full, dark sound. The JP133LR also features a durable string rotor mechanism ensuring the development of players is supported as much as possible.
