The GB4 Series

The Greenhoe GB4 series features a design based on the finest mid-to-late 20th century orchestral large bore tenor trombones. The GB4’s one-piece bell offers a broad sound and excellent projection with minimal effort. Subtleties and nuances abound with Greenhoe’s improvements to the classic design.
