Thought up by saxophone repairman and mouthpiece expert Jimmy Jensen and produced here at Lagan Music. These key height gauges are a quick and effective way to check and set key heights on saxophones. Insert between pad and tone hole without fear of damaging either surface. 


These are common sizes used on saxophones (in millimeters). If you'd like to request a different layout or different numbers please contact!
