The THEIN Jazz Tenor Trombone “Maxim” was designed in close collaboration with renowned jazz musicians, including Marques Young, Uwe Granitza, Jilt Jansma, and Jürgen Neudert.

Exceptional intonation, precise response, and outstanding control make this instrument an essential choice for professionals.

Its unique sound resonates with depth and character—vibrant, expressive, warm, and captivating. This is the “extra” quality that musicians seek and discover in the Maxim(um) experience.

An optional F-Attachment is available, expanding the instrument’s lower range with a full, rich, and focused tone—an especially valuable feature for studio recordings.
