The Griego 5 has a more rounded rim on a slightly deeper bowl than a standard Bach 5G. Consistent throughout all registers with lots of middle register overtones. This mouthpiece was designed with the principal trombonist in mind. Traditional "New York" style exterior is similar in appearance to Bach models, but slightly heavier, with the weight distributed evenly around the bottom of the cup. Features: • Gold plated • 25.50mm cup diameter • 0.280" throat
