Eastman ETB428G Tenor Trombone Overview
The Eastman ETB428G is a well-conceived intermediate Bb/F tenor trombone for players moving beyond a basic student instrument into larger ensemble literature. Its large-bore design, open-wrap F attachment, and gold brass bell place it in Eastman's performance-level trombone range, giving advancing players a more developed orchestral and wind ensemble setup while remaining approachable for serious study.
Eastman ETB428G Tenor Trombone Specifications

- Bore Size: .547 inch large bore
- Bell Diameter: 8.5 inches
- Bell Material: Handspun gold brass

Condition & Setup
This floor model instrument is in excellent playing order and has been professionally serviced, set up, and play-tested by The Mighty Quinn Brass and Winds. The lacquered brass surfaces retain a strong gloss, with minor fine surface scratches and handling marks from normal use. The slide, bell section, F-attachment tubing, braces, and rotor assembly are present and intact, and the included Eastman case is fitted for the instrument.
Who the ETB428G Tenor Trombone Is For
The ETB428G is intended for advancing students, strong high school players, college-track musicians, and adult players who need a large-bore Bb/F tenor trombone for concert band, orchestra, and larger brass ensemble work. The gold brass bell gives the model a warmer tonal concept than a comparable yellow brass bell, while the open-wrap F attachment supports smoother low-register facility and alternate-position work. It is a practical choice for players who are ready for a more mature trombone setup without moving into a fully professional custom instrument.
Common Questions About the Eastman ETB428G
What does the ETB428G offer compared with a basic student tenor trombone?
The ETB428G adds a large-bore Bb/F configuration, an open-wrap F attachment, and a gold brass bell. Those features make it better suited to symphonic band and orchestral tenor trombone parts than a small-bore straight student model.
How does the gold brass bell affect the sound concept?
Gold brass bells are commonly chosen by trombonists for a warmer and broader tonal color. On a large-bore Bb/F tenor trombone, that sound concept can be useful for ensemble blend, sustained lyrical playing, and fuller low-register work.
Is the ETB428G appropriate for serious school ensemble literature?
Yes. The ETB428G is built around the large-bore Bb/F format commonly expected for advancing tenor trombone players in wind ensemble, youth orchestra, all-state, and college-preparatory settings.
