The newly designed K&K Sound UltraPure Preamp features +/-20 dB gain for 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.
The K&K UltraPure Preamp is designed to be mounted at the edge of a standard soundhole. A 2.5mm male connector is provided to allow solderless connection of the included Pure pickup to the preamp. Includes battery holder and prewired 1/4" endpin jack, along with installation hardware and instructions. Fits round soundholes from about 3.75" to 4.25". Pickup not included.
