Powered by a 9 volt battery or externally supplied phantom power. (battery not included)
This 1-channel all-purpose preamp (magnetic/piezo) is an upgraded, slightly larger version of the Pure Preamp. It adds a phase switch and a balanced XLR output along with the ¼" line output (which you can use for a tuner or for stage monitoring). You can power the unit with phantom power through the XLR output, and its powerful EQ section and gain controls are all externally accessible.
K&K Sound preamps are full-range, and suitable for use with any pickup - due to their 1 megohm input impedance, they are ideal for piezo-based and magnetic pickups. Yep, I've been known to use my personal Pure Preamp with my old '71 Fender Precision fretless bass, which lets me get that "active" sound without making nasty new holes in that sweet old bass.

Thanks for the good advice you provide on preamps, and thanks for the quick service on the K&K, which arrived in time for three weekend gigs. The preamp makes a world of difference, even with my older Fishman BP 100 pickups, which are positioned under the bridge feet. I'm able to get a much warmer and controllable sound than I could by going through an external EQ. For the time being, at least, I'm off the hook for investing in a better pickup, and when I do decide on one, I'm sure the K&K will still make a big difference. Thanks again, Jene
