Used Donat Touvron "D" Trumpet Mouthpiece

Donat mouthpieces are an up-and-coming manufacturer out of Mont Blanc, France, and have made mouthpieces for a number of famous trumpet players, including Roy Hargrove, Rashawn Ross, Guy Touvron, and Erik Truffaz. 

The Touvron series was designed with Guy Touvron, and is similar to a Bach 3 diameter. The Touvron "D" model is slightly shallower than the standard Touvron piece, and Donat says it's similar in size to a Monette B6LDS1.
