Griego James Markey Bass Trombone Mouthpiece Overview
The Griego M87 James Markey bass trombone mouthpiece is a silver-plated bass trombone mouthpiece built around proven stock bass-trombone dimensions, refined with the GP rim profile that Jim Markey previously used on the GP Series. The design priorities are flexibility and a clear, immediate response, with a deep cup for a rich core and quick articulations while aiming to reduce the need to shift in the upper register compared with rim designs that can feel more “locked in.”

Who the M87 Bass Trombone Mouthpiece Is For
The Griego M87 is a deep-cup bass trombone mouthpiece designed for players who want a rich, centered sound with fast, reliable articulation and improved flexibility. It is well suited to serious students, collegiate players, and working professionals looking for a mouthpiece that speaks quickly at the front of the note with less effort while maintaining a full bass-trombone tone.
Within the Griego-Markey line, the M87 pairs deeper cup depth than the GP Series with the familiar GP rim concept Markey favored, targeting reduced “locking in” feel and less perceived need to shift in the upper register. This makes it a practical choice for repertoire that demands both breadth of sound and clean starts, including orchestral, band, and commercial settings.
