JP instruments JP173MKII Bb baritone horn

The JP173MKII is the second-generation model of John Packer’s popular entry level Bb baritone horn. Its easy playability and confident tone make learning on one of these instruments a thoroughly enjoyable experience, and the improved low-maintenance design will ensure years of reliable service.

Its yellow brass tubing starts with a bore diameter of 0.504” (12.8mm) and eventually flares into a large 8” (203.2mm) bell. The baritone horn’s body is coiled in an open wrap layout providing easy access to each of the braced cupronickel tuning slides and three water keys.

Like many starter baritone horns, the JP173 does not include a compensating system. This means that its range is limited in the pedal register and its intonation is a little inaccurate at the extremes of its range, but these things are unlikely to affect beginners.

A specially redesigned valve block features channels cut by a computer guided router and perfectly aligned nylon guides to establish the smoothest airtight action possible. Each of the horn’s valves is made from durable monel alloy and bottom sprung for easy maintenance.

All John Packer brass instrument outfits come supplied in a semi hard moulded case with comfortable handles and plenty of pockets for music and accessories. The JP173MKII baritone also includes a JP mouthpiece and a bottle of Ultra-Pure professional valve oil.
