An ideal mouthpiece for clarity, with a full sound, that is well balanced. Giddings & Webster's 1.25 GW 144 is similar to a Bach 1 1/4 orchestral mouthpiece with a slightly flatter rim, a #27 throat, and modified cup and backbore. The 1.25 GW 144 creates a clear, focused and articulate sound. Designed to increase endurance, accuracy, and projection in extremely loud and quiet music makes the 1.25 GW 144 a great trumpet mouthpiece.
