I upgraded to this mouthpeice from a Rico royal graftonite 5. This mouthpiece surprisingly sounds brighter on my conn selmer soprano and in a pleasant way. It has a nice solid feel to play and a good response for most of the register. I rated response as a 4 because, although I chose a 7 opening, I still can?t hit notes above top e flat with a la Voz medium soft reed. A harder reed is needed for that job!! But I?m totally happy with the feel and sound. A good mouthpiece for the money.
