I just ordered 4 mouthpieces from wwbw with their trial program and got a Otto Link STM, Otto Link NY, Guardala MBII and Guardala Crescent. I like the NY better than the STM and the Crescent better than the MBII so I'm down to the Crescent and Otto Link NY. I'm actually leaning towards the crescent because its so free blowing and seems to have that Coltrane sound that seems pretty close to him on Crescent. On the NY link I can't seem to get nearly as much volume and I like the tone a bit more also on the Crescent. I just feel reluctant getting the Crescent because it is is kinda bright much more so than the NY. If you have any opinions on the Crescent and whether or not i should get that or the link I'd love to hear it and I'm open to all suggestions. Also if it matters stuff about me and my playing is I'm 14 practice 2-3 hours a day alone and I participate in district jazz band and any jazz band I can get into. If you like I'll record a video on each of the mouthpieces if i get a request and the mouthpiece I payed previously was a rubber Jody Jazz 7*.
