K&K The Pure mini w/ Passive Volume Control

The Passive Volume Control works without a battery. It does not boost the volume, but it allows you to turn the pickup signal down.

It functions best when the input impedance of the device you plug your guitar into is 1 Mega Ohm (preamp/amp or mixing board-channel). If this input impedance deviates by a large amount (i.e. 100 Kilo Ohms or 10 Mega Ohms), you may experience diminished range (from “full volume” to “off” within a 1/3rd rotation) or, in extreme cases, a slight hum when the potentiometer is at middle position. This is a normal phenomenon when passive potentiometers are used with piezo based pickups. At “full-on” or “full-off” it will always be noise-free. A lot of customers use the Volume Control like an extended on/off switch.

The Pure Mini is our award-winning, signature pickup for steel string acoustic guitars. The Pure Mini is a 3-head, bridge plate transducer. It features super balanced, flat sound transmission, warm woody tone without any quack and superior dynamic range all over the guitar’s frequency spectrum. Our customers tell us that the Pure Mini’s output is louder than any other passive pickup on the market.

Bridge plate transducers are the optimal choice for achieving a rich, natural guitar sound. The Pure’s position on the bridge plate provides the perfect balance of sound, picking up all the strings without sounding harsh or percussive and “listening” to the sound board to amplify the unique characteristics of your guitar. The result is a warm, full-range signal that sounds great even without a preamp!
