The Mixpro is a belt-clip preamp/mixer that allows a perfect combination of almost any sort of pickup or mini mic. It places every essential control right at the player's fingertips, eliminating the need to modify a prize guitar for onboard electronics -- or to carry around a heavy, obtrusive rack. The Mixpro provides 9V phantom power for both channels, and, when it is used with the Buffer Jack accessory, you can say goodbye to batteries on your guitar.
