BLUESTiCK is a patented active transducer that places the miniaturized equivalent of a studio - grade condenser microphone under your guitar's saddle. It's the first acoustic guitar transducer to actually reproduce the sound of a guitar - instead of merely recreating it via imprecise piezo-ceramic mechanics. You'll enjoy extended frequency response, microscopic detail and up to 30dB more dynamic range than with old technology transducers.
