No, I didn't NEED yet another mouthpiece, but the black mambo has intrigued me ever since Steve came up with it. Ordered one & gave it a test run today. It's on my #2 neck of my Goodson-designed Orpheo black nickel tenor. It has a #2 Fibracell Premier reed attached. The results are unlike anything I've experienced before. There's a richness to the sound you have to play/hear to believe. I suspect some sort of voodoo MUST have been invoked!
On top of that, it's simply gorgeous....not just another plain black mouthpiece.
