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 build quality on the Bb/F is exceptional. It feels as you would expect a professional model to feel. The sound is a little more centred than the Bb. The valve has a free, quick and precise action and all the notes work well. The F side notes are great all the way down to bottom D's and the pedals below. The case has a very high specification (based upon the current Bach Stradivarius cases) and this also comes complete with rucksack straps for greater convenience. Both instruments represent excellent value for money and are ideal for the aspiring trombone player. I could get away with either of these on a Halle gig.
