K&K Sound Pure Preamp

Manufactured by: K&K Sound

Pure Preamp
Designed as an all-purpose preamp for piezo and magnetic pickups, it can be used for many pre-amplification purposes. The specially designed EQ has a super-wide band midrange control centered at 1.5 kHz plus bass (100hz) and treble (10kHz) controls. This very clean circuit has gain, active (+/- 20dB) bass and treble controls, an internal gain trim pot for 1x to 10x preamplification. Just a tiny bit over 8 ounces with battery.

Steel case approx. 2 3/4 x 2 1/2 x 1 1/2 inches. Powered by a 9 volt battery (not included).

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. Yup, I've been known to use my Pure Preamp with my old '71 Fender Precision fretless bass, for that "active" sound without making nasty new holes in that sweet old bass.

Do you need a preamp?
You may or may not, but it's good to know if there is a technical and/or practical reason for having one for your pickup. Click on the FAQ link below "Do You NEED a Preamp..." that discusses impedance matching and using piezo pickups with "normal" amplifiers.

All K&K Preamps have the same basic specifications:

• Frequency range 10 - 30,000 Hz
• Input Impedance: 1 Mega Ohm
• Output Impedance: 3 K Ohm
• Average Current: 3.5 mA
