K&K's Ultra Pure onboard active system has been completely redesigned in response to customer feedback. 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. The system also includes a volume control and low battery indicator.
Installing the preamp requires no alteration to your instrument. The preamp is mounted inside the guitar at the edge of the soundhole, giving you convenient access to the controls during performance.
The Ultra Pure Preamp is also available as a complete system with K&K Pure Mini, Pure Classic or Pure 12-String transducers.
