The K&K Pure XLR Preamp is designed to be used in conjunction with its line of Pure pickups; however, due to the inclusion of an adjustable input gain and its wide range, it works with many other applications just as well. Featuring a +/-20 db bass, mid, and treble controls, you get an intuitive control setup that takes seconds to tweak to find your tone - and with the input gain control, you can get even more out of it.

Additionally, a phase switch is included, which may be the most useful tool in this device's arsenal. It acts as a feedback-controlling device, but also can be used to "sync" your instrument's soundwave with the speaker from which it's projecting, effectively allowing you to instantly correct the tonal inconsistency between the two.

It has an LED light to indicate phantom power's presence, and it can be powered by a 9-volt battery. The K&K Pure XLR Preamp is an incredible system for your acoustic rig.
