K&K Pure Preamp
The Pure Preamp is our time-tested external preamp, featuring +/-20 db bass, mid,
and treble controls plus an internal gain trimmer. This beltclip unit has been specifically
designed for the frequencies of the acoustic guitar but it is also great for many
other instruments. The Pure Preamp features a special super wide band midrange filter,
which is absolutely great in combination with the Pure pickups. Its simple and noiseless
circuit provides unsurpassed clarity and power and the internal gain trimmer allows
you to dial in the precise amplification factor needed for your instrument.
Frequency response is 10-30,000Hz. The bass control is set to roll of at 100Hz, the
midrange at 1.5kHz with extra large bandwidth and the treble are set at 10kHz.
Input impedance is 1 meg and the output is low ohmic. Battery live is about 180+
hours.
