Laskey 55 SOLO Alessi Signature Trombone Mouthpiece Overview
The Laskey 55 SOLO Alessi Signature Trombone Mouthpiece (Large Shank) is a precision CNC-machined brass trombone mouthpiece designed in collaboration with Joseph Alessi, Principal Trombone of the New York Philharmonic, and built for consistent feel, response, and tone across modern large-bore tenor trombone setups. The 55 rim size is comparable to a traditional 5G, pairing a comfortable rim and added weight with a custom Solo cup intended to deliver a balanced all-purpose setup for articulation, core, and flexibility.

Who the 55 SOLO Alessi Signature Trombone Mouthpiece is For
The Laskey 55 SOLO Alessi Signature Trombone Mouthpiece is a large-shank tenor trombone mouthpiece designed to provide a balanced, do-everything Solo cup setup with a rim size comparable to a traditional 5G. It is well-suited to advancing students, conservatory players, and working professionals who want a mouthpiece that supports a centered sound with clean response and reliable consistency from piece to piece due to high-precision CNC machining.
Within the Alessi Signature Series, the 55 size targets players who prefer a familiar 5G-style rim feel, while the optimized Solo cup is built around an intentional balance of throat size, backbone, cup, and rim for versatility across orchestral, solo, and commercial demands. (For reference within the series: the 60 rim size aligns well for players coming from 4G-5G sizes, and the 67 is the largest option for maximum room and comfort.)
Common Questions About the Laskey 55 SOLO
Is the Laskey 55 SOLO a good alternative to a 5G?
Yes. The 55 rim size is designed to feel similar to a traditional 5G, with a comfortable rim profile and added weight, plus a custom Solo cup aimed at improved sound and response.
What does the “Solo” cup mean on the Alessi Signature Series?
The Solo cup is designed as an all-around option with a deliberate balance of throat size, backbone, cup, and rim, intended to maintain flexibility and clarity while supporting a centered tone.
Will this mouthpiece fit my trombone?
This model is a Large Shank mouthpiece for large-bore tenor trombones that take large shank receivers. If your instrument uses small shank, it will not fit correctly without an adapter or a different shank version.
