Designed in collaboration with Argentine trumpeter Juan Cruz de Urquiza, this signature mouthpiece features a distinctive semi-flat rim and a 160-gram weight that gives it a unique feel in your hand and on your chops. It's available in two sizes: the JP, which is slightly smaller than a Bach 3 with a tapered C cup for versatile all-around playing, and the BLP, which sits between a Bach 1 and 1-1/2C with a deeper cup suited for orchestral and big band work.

The semi-flat rim is surprisingly comfortable for extended playing sessions and provides excellent stability in the upper register. This is a mouthpiece born out of real-world professional demands -- de Urquiza needed something specific for his playing, and All Brass crafted it by hand. If you're looking for a mouthpiece with character that goes beyond the standard catalog options, this is worth trying.
