Find the tip opening size on any woodwind mouthpiece. The tip opening is the distance between the reed and the mouthpiece tip rail. A bigger tip opening takes more air to fill the horn; a small tip opening takes less. Mouthpieces are notorious for not measuring as they are marked, and this tool will help you find your mouthpiece's actual opening.

Our gauge body is made from gold anodized solid billet aluminum. Included is the digital gauge and our accurate tip which allows for visibility of the tip rail.

This is an indispensable tool for musicians with multiple mouthpieces and for retail stores selling mouthpieces. It allows you to compare various models for tip size. This is necessary in choosing a comfortable mouthpiece, and for comparing models as tip openings may be inconsistent in both vintage and new mouthpiece models.

Millimeter measurements on the side of the gauge measure distance from the tip rail for plotting baffle and rail measurements.
