RainSong Graphite Guitars has developed SFT: Soundboard Fusion Technology that combines the stability and robustness of carbon fiber with the traditional aesthetics and tone of wood. After careful experimentation, we fused a thin spruce soundboard and a unidirectional pre-impregnated carbon top in a single molding step. The resulting SFT soundboard is a composite matrix that resonates as a single unit, like a solid wood soundboard. The physical properties of the carbon fiber far exceed those of the thin wood. Hence the SFT soundboard maintains the imperviousness to humidity and temperature of carbon fiber.

An SFT soundboard delivers rich crystalline carbon sound subtly colored by wood.

– Combines the best qualities of Carbon Fiber and Spruce in acoustic guitars – Rich crystalline Carbon acoustic guitar tone subtly colored by spruce – Unaffected by humidity and temperature variations
