Many manufacturers of French Horn mouthpieces offer their models in different inner diameters. Laskey offers their “G” mouthpiece in sizes ranging from 17 mm to 18.5 mm (725G-85G). Our Verus VX mouthpieces are offered in sizes from 17.25 mm to 18.25 mm. Even our Houghton H1 rims come in sizes from 17.25 mm to 18.5 mm. How do you choose the correct inner diameter for you?
