The ZO ZTU-2500 is an intermediate-level BBb tuba designed for advancing students who are ready for the added flexibility of a 4-valve instrument. It bridges the gap between the ZTU-2000 student model and ZO's larger professional tubas.
The ZO ZTU-2500 is built for musicians ready to move beyond a basic student instrument. Featuring four responsive front-action stainless steel pistons, a compact 3/4 BBb design, a rose brass leadpipe, and durable brass construction, it delivers a warm, resonant sound with excellent intonation and improved low-register performance. Lightweight enough for students yet capable enough for advanced ensemble playing, the ZTU-2500 is an outstanding choice for school band programs, community ensembles, and musicians seeking professional features at an exceptional value.
