Soundboard Fusion Technology

February 8, 2020

To combine the stability and robustness of carbon fiber with the traditional aesthetics of wood, RainSong has developed SFT:  Soundboard Fusion Technology.

After careful experimentation, we are able to fuse a thin spruce soundboard and unidirectional pre-impregnated carbon (prepreg) 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 unidirectional carbon fiber far exceed those of the thin wood.  Hence the SFT soundboard maintains the imperviousness to humidity and temperature variations of carbon fiber.

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