Eastman ETB849 Bass Trombone Overview
The Eastman ETB849 is a professional bass trombone designed for players who want an independent dual-valve system with the open feel associated with axial-flow valves. It occupies Eastman's professional bass trombone line and is well suited to orchestral, wind ensemble, brass ensemble, and commercial low-brass work, while its interchangeable leadpipes allow the player to refine response and resistance.

Who the ETB849 Bass Trombone Is For
The ETB849 is intended for professional bass trombonists, conservatory players, and serious ensemble musicians seeking a broad, centered bass trombone voice with an open attachment register. Its independent axial-flow valves support flexible low-register fingering, while the interchangeable leadpipes provide useful options for adjusting response and resistance to the player and performance setting.
Common Questions About the Eastman ETB849
How do the axial-flow valves affect the ETB849's response?
Axial-flow valves are designed to maintain an open air path through the attachment register. Players often choose this design for its free-blowing low register and consistent feel when moving between the open instrument and valve combinations.
How does the ETB849 differ from the Eastman ETB848?
The ETB849 uses independent axial-flow valves, while the ETB848 uses independent rotary valves. Both belong to Eastman's professional bass trombone line, but the valve designs provide different airflow, response, and ergonomic characteristics.
What is the purpose of the interchangeable leadpipes?
Interchangeable leadpipes allow a player to compare different balances of resistance, articulation, and response without changing the core instrument. This is particularly useful for professionals adapting the trombone to different ensembles, mouthpieces, and playing preferences.
