This is a Drake vintage resin soprano mouthpiece. It is called the “Son of Slant” in reference to a vintage Otto Link Slant soprano mouthpiece. Here is the description from the Drake website of the mouthpiece:
The design of this mouthpiece has been modeled after the Otto Link Slant model, with a few modifications to help facilitate better stability of pitch and greater projection. The floor slope has been raised and extended. Amazing warmth and depth to the tone with a great expressive range. Featuring beautifully under cut walls and a chamber dimension larger than the shank diameter with a carefully contoured roll over baffle.
Drake Son of Slant Soprano Saxophone Mouthpiece
This mouthpiece has a .065 tip opening which is what I prefer on soprano. It has a pretty large chamber in it. Larger than most of the soprano mouthpiece I have tried. The only mouthpiece I have tried with a bigger chamber was a Morgan 6LC mouthpiece that I tried once. The bigger chamber gives it a bigger fatter sound in my opinion. Not bright at all, more on the dark side of things in my opinion. At the same time it has a nice ring to the tone that I really enjoyed. If I had to pick one word to sum up the sound of this mouthpiece it would be “sweet”. Check out the Drake website for more info on this soprano mouthpiece. Let me know what you think. Steve
