I'm a relative beginner, I had only played on a 7C before, and I was keen on trying something else. This mouthpiece won me over almost instantly. I mainly play jazz and I find that this mouthpiece indeed adds that jazzy, bright tone more so than my 7C. It also is louder and projects a fuller sound. Personally, I also find the wider diameter to help with my endurance, but that will be player dependant. I did have to slightly readjust to get out the higher register, but that could very well be my lack of experience.
For the price I'm absolutely satisfied with the product and would recommend if you want to try out a new mouthpiece.
