Besson 2052 Prestige Compensating Euphonium

From Besson: "The Prestige 2052 euphoniums feature the main tuning slide trigger system and unique lead pipe design and are the instruments of choice for many of the world’s professional soloists and band players alike. With the creation of the Prestige models, the combination of the redesigned valve group assembly, the new lead pipe, and the adjustable main tuning slide trigger means that the tuning is now totally controllable, giving the musician everything they need to play with perfect intonation in any circumstance, be it with piano, brass, wind band, or orchestra."
