Orchestral players who play a 59 or 1¼ will love the feel of the Griego 1. Most bass trombone mouthpieces are unbalanced, which causes a wide array of sound widths and tonal colors throughout the different registers. We have paid very close attention to the balance between the cup, throat, and backbore of our mouthpieces. The end result is a mouthpiece that maintains tonal color no matter the tessitura. The upper register maintains the core sound without becoming diffuse. The lower register is full with plenty of energy in the sound. Cup Diameter: 1.118" or 28.40 mm, Throat: .315". The Deco blank is heavier in mass than the NY blank. The added weight is great for large bass trombone mouthpieces that may have thinner walls due to larger inner cup diameters. It is very free blowing and can provide a bigger, darker sound than mouthpieces with less weight. The Deco also provides stability, which can help define partials on those trombones where extra focus is needed. The NY blank weighs slightly more than modern day Bach mouthpieces (Elkhart blanks). Its weight is distributed evenly around the bottom of the cup. This results in an even core of sound with overlapping overtones, creating a tone quality that is thicker than conventional mouthpieces. The NY also provides the midrange overtones that are often lost with other mouthpieces. Our newest mouthpiece blank, the Nouveau was created to give trombonists the flexibility a lighter mouthpiece can provide. It provides a width of sound and wider partial feel for a natural playing experience. Every tone and timbre can be manipulated, making the Nouveau a very expressive mouthpiece.
