Developed with top artists The YTR-9825 was developed with John Hagstrom of the Chicago Symphony Orchestra. Two sets of leadpipes The YTR-9825 comes with 4 leadpipes. Two leadpipes have trumpet mouthpiece receivers in Bb and A while the other two have cornet mouthpiece receivers in Bb and A. Hand-hammered one-piece bell A one-piece bell has an axial (lengthwise) seam, making it a continuous extension of the instrument's material. This results in pure, uniform resonance and superior tone. A hammered yellow brass bell produces a perfectly-balanced tone with quick response and extra presence due to advanced manufacturing. Hand-lapped pistons and slides Hand-lapping pistons and slides ensures an absolutely perfect fit and seal between the pistons and casing or slide parts. Such a perfect fit helps to achieve smooth air flow and smooth action and improve the response and intonation of the instrument. Pressure formed tubing Perfectly rounded tubing results in less turbulence and a smoother air flow, thus allowing for an excellent scale and reduced resistance. |
