The GBC-300 is a solidly constructed student to intermediate instrument intended to give the learning musician an affordable instrument to develop his or her skills on. It is built with quality materials and craftsmanship that ensure it will withstand the rigorous student treatment an introductory instrument can sometimes undergo.

In addition to a hard rubber two-piece body, it features a nickel-plated neck, mouthpiece receiver, bell and keys. The package is made complete with a molded ABS case on wheels and a five-year warranty.
