Schilke Symphony D Series Trumpet Mouthpieces
"models are on the larger side of the mouthpiece spectrum creating a deep, vibrant sound with a well-focused center. Conceptually developed to meet the demands of the modern orchestral player, these new models have comfortable rim shapes that provide a nice clarity in attack. The cups on the D1, D2, and D3 are deeper bowl shape cups for players needing more depth in their sound, but provide enough feedback for control."
