GR Parameters, Terms, and Definitions

In order to communicate effectively with our clients, we have decided to include the following list of mouthpiece parameters, terms, and their definitions.

Please note that a number of these terms were created by Gary Radtke in order to quantify mouthpiece parameters. For example, the term Alpha Angle was never used in the industry before GR Technologies. Instead terms like, undercut, drop off, and relief were used. None of those terms actually define that particular parameter.

Thankfully more and more, GR terms are being used more and more in the industry. So much so that some other manufacturers are now using them on their websites! That says a lot for GR!
