The Model 551S Bb Euphonium has a completely re-designed bell and superior all round optimization in intonation - especially on the 6th and 3rd partial, with a main tuning slide trigger for adjustment. At the same time, the instrument plays with a previously unexperienced warm and big sound. A water catcher to prevent drips on the player while performing. The 551 is exclusively offered in silver-plated and is optically refined with gold-plated top and bottom valve caps. Includes case and large shank mouthpiece.
