System Blue’s Professional Marching Brass Series is built with an eye toward the advanced player. Our superior design is rooted in decades of experience and success in the marching arena, as we recognize the demands and challenges required for excellence. We knew it was time to create brass instruments that speak as individual voices, blend as a choir, and project clearly both near and far.

Designed for comfort with new ergonomic hand positioning, our Euphonium Hybrid gives a balanced feel while reducing weight and length. Our graduated tuning slide marks will keep you a quick step away from fine tuning at any venue, in any weather condition.

Every System Blue Professional brass instrument is available in silver or lacquer finish with contrasting finger buttons.
