Grassi GR STU300 School Series Tuba – B♭

Grassi GR STU300 School Series Tuba – B♭ (¾-Size)

The Grassi GR STU300 is a student-level B♭ tuba from the Ida Maria Grassi School Series, designed to provide beginners and young learners with a manageable yet full-sounding brass instrument. Its ¾-size format, combined with lacquered brass construction and three top-action piston valves, makes it ideal for school bands and student musicians requiring an instrument that balances ease of handling with reliable tonal output.

With its 425 mm bell and 19 mm bore, the GR STU300 delivers solid projection while remaining more accessible in size and weight compared to full-sized tubas. The nickel-plated pistons ensure smooth valve action, while the included foam case (sometimes with wheels) provides convenience and protection for transport.
