I received my American Cut for tenor from Amazon and after playing it throughout the weekend, here are my impressions. I do like the tone and response for jazz better than the Signature cut. The altissimo response is excellent and it subtones well. The tone is just a little brighter than the Signature and the response is in my opinion a little more free blowing than the Signature. However, I still think the Alta Ambipoly Jazz reed by Silverstein Works is by far the best synthetic ever made (and I have tried them all). The Silverstein is to me the only reed with a warm, cane-like response and tone. Silverstein claims this reed was designed to absorb moisture just like cane. I can't say for certain that is the reason, but playing is believing. The Silverstein sounds amazing on any mouthpiece I have tried it on, whether hard rubber, metal, small or large tip opening. The Silverstein Jazz produces about the same amount of buzz as a cane reed. I think my altissimo sounds better on the Silverstein than a cane reed. I have always found cane to be rather bright in the altissimo register, especially with my *8 metal jazz mouthpieces but the Silverstein produces a tone that darkens up the altissimo register nicely. The Silverstein is expensive and as of now you can only get their clarinet and alto reeds from Woodwind and Brasswind, so you have to order the tenor reeds directly from Silverstein. However it was worth the money. I have been playing on the same Silverstein Alta Ambipoly tenor reed since January and I play my tenor around 5 to 15 hours a week. So I am expecting to get a year, maybe a year and a half out of this reed.
