A couple of months ago I bought a Metal Meyer Jazz (7J) mouthpiece. I absolutely love it, it have a great clean tone and it allows you to play really powerfully but still be in control. I would definitely recommend this mouthpiece to anyone that likes clean powerful sounds. Keep in mind, an opening of 7 is very large so it makes reeds play harder than they do on a 4C for example. I used to play a size 4 reed on my 4C and 6C mouthpieces so I have now changed to a 2.5 reed on this one.
