I was at the music shop today talking with the owner who happens to be a sax player as well and we were discussing mouthpieces. He stated he used a Runyon mp on his tenor that had a spoiler insert that would give the sax a grittier sound. It looks as tho there was a metal insert inside of the mouthpiece that would vibrate as well as the reed to give the sound. Just wondered if anyone had any experience with these and if it really has that big of an effect on the sound?????
He said Jody jazz took over and has the patent on these spoilers now. Just looking for what others have to say about this.
