The GREENHOE GC4 Bb/F Tenor Trombone is a remarkable embodiment of the American-style large bore trombone in its most elegant and refined form. Inspired by early 20th-century classic trombones, the GC4 combines an iconic design with advanced technical features.

One of the distinctive aspects of the GC4 is its extremely responsive two-piece bell, offering exceptional response and powerful sound projection. The unsoldered rim of the bell contributes to enhanced resonance and allows greater freedom of vibration, resulting in an expressive and nuanced sound.

Carefully crafted at Schilke in the United States, every detail of the GC4 speaks to Greenhoe's commitment to quality and perfection. The 0.547-inch (13.89 mm) bore allows for excellent flexibility and ease of play, offering a quick response across all registers.

The meticulously assembled 8.50-inch (216 mm) two-piece bell ensures exceptional tonal accuracy and optimal projection. The choice of yellow brass for the bell material adds additional warmth and richness to the trombone's timbre.

The yellow brass slide offers smooth and precise action, allowing musicians to explore a wide range of techniques and playing styles. Each slide is meticulously adjusted to ensure perfect airtightness and a smooth response.

The Greenhoe valve is a key element of the GC4, contributing to its distinctive sound and precise intonation. Designed with great attention to detail, the valve ensures a consistent response and optimal ease of play.
