In order to get exactly the kind of tone colors he wants, Bobby uses two different trumpet mouthpieces. The 'Jazz' model is his usual all-around choice. It has a fairly deep roomy cup for a warm, big sound, and a throat and backbore designed to give enough "jump and snap" for maneuvering through quick jazz passages with a rich full sound. The 'Lead' model, on the other hand, gives that extra sizzle and high note clarity for playing lead parts. It features enough air compression for high range playing, but still allows a big open sound.
