K&k Power Pack Preamp

The K&K Power Pack may be the smallest most powerful beltclip preamp on the market today. Designed to pre-amplify piezo pickups, it also works great with electric guitars or basses or for any other pre-amplification purpose. The Power Pack is practically noise-free and has a long battery life, up to 250 hours. It can process high input peaks without distortion and offers an incredible dynamic range. Besides its strong bass and treble filters (+/- 20dB !), it offers an internal gain adjustment. A trim pot inside the unit (for adjustment with a small screw driver) sets pre amplification factor from 1 to 10. This means, you can boost the input signal up to the 10 fold amount.
