I liked the feel of this mouthpiece when I bought it, but I discovered it was well suited for something other than jazz on a Bb trumpet. It has a nicely rounded rim and an open blow which makes it set up well for jazz, big band or combo work. However, the rim diameter is a little narrower than a traditional Bach mouthpiece of comparable cup depth. I found that the rim, rounded and narrower, worked very well on a Yamaha piccolo trumpet! A big, easy to tune sound without being overly bright.
