Eastman EPH495S Sousaphone Overview
The Eastman EPH495S Performance Sousaphone is a brass BBb model developed for marching and outdoor ensembles that need a conventional contrabass voice with direct projection. Positioned in Eastman's Performance lineup, it uses the familiar three-piston, forward-bell format expected by school, collegiate, community, and ceremonial ensembles. The EPH495S is a useful choice for players and programs seeking a silver-plated brass sousaphone rather than a fiberglass design.

Who the EPH495S Sousaphone Is For
The EPH495S suits advancing students, educators, and ensemble programs looking for a brass sousaphone for marching band, pep band, parade, and ceremonial work. Its piston-valve layout offers a familiar response for tuba players, while the forward-facing bell supports the direct projection required in mobile and outdoor settings. It is best matched to musicians who need a dedicated marching instrument rather than an upright concert tuba.
Common Questions About the Eastman EPH495S
How does the EPH495S differ from the EPH395S?
The EPH495S is a brass sousaphone with a 25-inch yellow brass bell, while the EPH395S uses fiberglass construction. Both are BBb three-piston models with a 0.689-inch bore, but their construction serves different preferences for handling, durability, and tonal character.
What does the 0.689-inch bore contribute?
A 0.689-inch bore provides a practical balance between airflow and resistance for marching use. It supports a full contrabass sound without requiring the air volume associated with many larger-bore concert tubas.
Where does the EPH495S fit within Eastman's lineup?
Eastman identifies the EPH495S as a Performance-level sousaphone. It is intended for advancing players and active ensemble programs seeking brass construction, a full-size forward bell, and a conventional three-piston configuration.
