The Green Series guitars offer three key technologies from Furch. A special intonation method is used for the resonating top made of Sitka spruce. Furch's unique full-pore high-gloss finish enhances the sound and improves the resonance of the guitar body. It can be further accentuated by a first-class sunburst tint on the top. Precise tuning for ultimate performance on stage is provided by the Composite Neck Reinforcement System (CNR) and the instrument is protected by a high quality, thermally insulated Hiscox housing. The combination of these elements makes the Green Series an excellent companion for every player.
