Alan Baer and Giddings and Webster have taken the original signature model mouthpiece and put a flatter narrower rim on it. In addition to this we have added a bit of mass around the throat of the mouthpiece, and we have made the mouthpiece out of 15-5 stainless steel. All of this combined makes a mouthpiece that is for folks who like a traditional flat rim with a sharper inner bite for their orchestral tuba playing needs. The 15-5 stainless steel is a high quality aerospace material that is harder than our regular 304 stainless steel mouthpieces.

The D5.1, D5.2 and D5.3 mouthpieces have deeper cups, providing increased depth of sound. The * models have a more tapered throat which will feel more open and will have increased flexibility.
