We're glad to hear you're getting on well with your YTR-2330.
Regarding an alternative mouthpiece for Jazz, we'd suggest the following models:
- 14B4 & 15B4:
- These have slightly wider rims and a deeper cup; these are ideal for getting a stronger lower register
- This mouthpiece is designed for lead trumpet playing and works well for Jazz - however, it may require more effect when playing the lower register
- This has a smaller rim and is an excellent all-round mouthpiece able to cover Jazz, classical and other genres without difficulty
- Bobby Shew Jazz:
- Similar in size to the 14B4, the Bobby Shew Jazz Signature mouthpiece has a 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
