Sumner Bb Clarinet Mouthpiece

Notes from Brad Behn:

 

Sumner mouthpieces were not well known, however their prowess as a true-Vintage ideal is formidable. This beautiful mouthpiece was manufactured from Sumner's exquisite in-house rubber formulation. Its resonance represents the ideal full body, rich overtone series, and wonderful ringing tone of the best mouthpieces of the post-war era. Vintage Kaspar buyers need not look any further as this mouthpiece is better—guaranteed!

 

This is a beautiful representation of a Sumner Acousticut 3 mouthpiece, and I restored it to a level better than the original. Its medium facing measures 1.05mm at the tip, and its length is 18mm. It is perfectly balanced, and it plays beautifully.  

 

If you have been searching for a vintage Kaspar mouthpiece, you will save a lot of money, and you'll experience a better level of performance with this Sumner. It is made from rubber which is at least as good, its facing is meticulously applied, and wonderfully responsive, and its sound is glorious. You won't be disappointed.
