Yamaha - YEP-642TSII Neo Euphonium

The Yamaha YEP-642TSII Neo is a professional euphonium that's equally at home in solo or ensemble settings, and it blends seamlessly with baritone and tenor horns. This dual-bore euphonium exhibits an energetic response with robust projection, and its incredible valve action takes comfort and playability to a whole new level. The YEP-642TSII includes four monel alloy pistons, in a 3+1 configuration, with a compensating tuning system that ensures accurate tuning throughout the instrument's range — especially on those difficult low notes. Furthermore, it comes equipped with a main tuning slide trigger to adjust intonation on the fly. Hand-lapped valves and slides supply a perfect fit and seal, exhibiting effortless air flow, smooth action, and amazing response. What's more, this horn's silver-plated brass body lends an ear-grabbing brilliance to every note you play. The Yamaha YEP-642TSII is tailor-made for players with discerning tastes. If this describes you, the YEP-642TSII may just well be the last euphonium you'll ever need to buy.
