The Hans Hoyer model G10 is styled after the original instruments by Carl Geyer, who immigrated to the United States in 1903. The well balanced design is very similar to the originals of the 1950’s with rich tone colors and similar resistance.

Careful attention was given to the balance and positioning of the braces, as well as to the ergonomic arrangement of the valve levers.The adjustable thumb lever and finger hook allow for comfortable fitting to the player’s hand.
