Long Island Brass Co. Eon Series Mouthpieces

The Eon series was built to sit at a specific intersection in the Long Island Brass Co. lineup — the playability and ease of the Standard and Chimera series combined with the powerful, direct sound of the Romero Signature models. The result is a mouthpiece that's full and rich throughout the range without losing access to the extremes or sacrificing flexibility when the music demands it.

Three models cover the most common playing needs in orchestral, concert band, and jazz settings:

Eon 550 — A Bach 5G equivalent built for players seeking more resonance and core. Medium deep cup, 25.5mm inner rim diameter, .280" throat. Warm and centred with the depth to support a strong low register.

Eon 600 — A 4G size mouthpiece with more focus and firmer slotting. Deep cup, 26mm inner rim diameter, .280" throat. More controlled than the 550, with a tighter feel that suits players who want precise response and reliable note placement.

Eon 650 — Deep and resonant like a 3G, with the focus and firm slotting that a mouthpiece of that depth doesn't always deliver. 26.5mm inner rim diameter, .280" throat. Also works exceptionally well for bass trombonists doubling on euphonium.

All three models are available in large shank. Built to the same CNC precision and exacting standards as the rest of the Long Island Brass Co. lineup.
