The K&K Pure Preamp features a special super wide band midrange filter, which is absolutely great in combination with the Pure pickups. Its simple and noiseless circuitry provides unsurpassed clarity and power and the internal gain trimmer allows you to dial in the precise amplification factor needed for your instrument.
- The bass control is set to roll off at 100Hz.
- Midrange at 1.5kHz with extra large bandwidth and the treble are set at 10kHz.
- Battery life is about 180+ hours.
- On the rear of preamp are two 1/4-inch jacks (input and output).
- The output jack also doubles as battery switch. When unplugged, it disconnects the battery when not in use.
