I have been playing a Guardala studio for about three semesters now and I love the sound i'm getting out of it. The only problem is that I feel the tip is too open. I'm looking at getting something around a 7* but still has that punch the Guardala has. Mouthpieces I have tried include jody jazz dv, otto link ny and stm, vandoren java, v16. They are all good mouthpieces but don't have what I am looking for. Im still planning on trying a Theo Wanne datta, Morgan Excalibur, and maybe a ponzol. Im not sure. If you have any recommendations, please let me know!
