Theo Wanne Bite Pads Sample Pack, incl. 2xhard and 4xstandard (medium), fits all Theo Wanne Alto, Tenor and Baritone mouthpieces. Hard: Creates the feel of hard rubber. Hard enough for the teeth to slide on the mouthpiece beak, but soft enough to absorb vibrations. Great for those in the Joe Allard school of playing. Standard: This pad has a good overall feel. Teeth do not slide but stay in place on the beak of the mouthpiece. This is the same bite pad supplied with all Theo Wanne mouthpieces.
