The UltraPure System is an active (pickup + preamp) system for acoustic guitar. It consists of K&K's award-winning Pure Pickup, an onboard preamp with soundhole access, an endpin jack, and a Velcro mounted 9-volt battery holder.
The newly designed UltraPure Preamp features +/-20 db bass/low, K&K's proprietary wide band midrange, and treble/high controls, plus internal gain trimmer. The addition of a phase switch is one of the most important tools for live sound amplification. Also includes a volume control and low battery indicator. All features are easily accessed at the soundhole.
Bridge plate transducers are the optimal choice for achieving a rich, natural guitar sound. The Pure's position on the bridge plate provides the perfect balance of sound, picking up all the strings without sounding harsh or percussive and "listening" to the sound board to amplify the unique characteristics of your guitar. The result is a warm, full-range signal that sounds great even without a preamp!
