Griego "Ian Bousfield" Signature Mouthpieces

Regarding the numbering system. Try to look at the numbering system different than than typical mouthpieces. For me the 4 has always been an anomaly and has not fit correctly in many series. My 4's will not feel as big as you might expect. If you are after a more traditional 4 feel, then you may consider the 3's as they will "feel" more like the traditional model 4's.
