The original custom alto mouthpiece by Christan Griego and Toby Oft, this mouthpiece is designed to make response and easy tone production a breeze. The blank is lighter, which allows a wide variety of colors to be chosen from and used within the sound palate. This piece soars in the upper register, providing brilliance when pushed. It is most often used for middle Romantic repertoire like Schubert and Brahms.

The Original Oft Alto Mouthpiece has a cup diameter of 1.004" and a .226" throat. This piece is amazing to play on Kruspe-style altos as well as traditional American altos. It was well received at the 2015 American Trombone Workshop, selling out in the first day.
