To combine the stability and robustness of carbon fiber with the traditional aesthetics of wood, RainSong has developed SFT: Soundboard FusionTechnology. After careful experimentation, we are able to fuse a thin spruce soundboard and a unidirectional pre-impregnated carbon 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.
