Who the James Markey Bass Trombone Mouthpiece Is For

The Griego M90 is a deep-cup, silver-plated bass trombone mouthpiece built for players who want a rich core sound, quick articulations, and improved flexibility without feeling locked into a single rim position. Developed from tried-and-true bass trombone mouthpiece dimensions, it uses the familiar GP rim concept to help the upper register feel more accessible by reducing how much many players need to shift as they ascend.

The deeper cup design supports breadth and depth of tone, while the design emphasis on the front of the note is intended to make the sound speak quickly with less effort. This model is a strong fit for serious students, working professionals, and orchestral or commercial bass trombonists who prioritize response, clarity, and consistent feel across registers.
