Hatched by a cadre of music industry vets and a Kansas inventor who's worked on both instrument tonality and airplane nose cone aerodynamics, this acoustic/acoustic-electric sound-hole insert dramatically enhances even a crappy guitar's clarity, volume, and projection, while also suppressing feedback. The rig was road-tested by Grammy-winning producer Neil Dorfsman, who's magically touched artists from McCartney to Def Lepperd -- and now believes that, while Love must Bite, your guitar's sound doesn't have to, especially once they perfect their device that keeps you from ever playing "Blackbird".
