Major Symphony Audition Winner - Patrick Walle used this mouthpiece to win the utility horn audition for the Detroit Symphony!
By pure technical specification, it's just a 19 bore GS, or an American Shank M, or a slightly deeper G. The GM though is a situation where the sum of its parts isn't the full story.
What it is - a control mouthpiece that lets you control control volume and color with more independence than any cup I've tested before. You can choose from a diffuse to a direct sound while always keeping a dense, composed core.
This also makes it a great fit for very light horns or horns that tend too bright because the extra control lets you really hone in on the experience you want to project to the audience.
