Eon Series

Tenor Trombone Mouthpieces

Easy &

Powerful

Our main focus when developing the Eon line was keeping a more traditional and approachable blow, while maintaining the feel our players have come to know and love.

The Eon line combines the playability of the Standard and Chimera series with the powerful, direct sound of the Romero Signature mouthpieces. A truly unique sound within our line, these mouthpieces are full and rich without losing access to the extremes or sacrificing flexibility.
