Unique benefits

Designed in collaboration with Smith-Watkins, the JP271SW benefits from their specialist expertise and professional components. Constructed from a High Grade 80:20 Brass, the JP271SW features a one piece bell for extra resonance, and high tolerance monel piston valves. A specially designed Smith-Watkins leadpipe offers a free blowing experience and encourages a warm tone. The JP271SW features 1st and 3rd valve slide triggers similar to professional models to assist with tuning.
