The K&K Volume Control is a non-destructive, plug-and-play addition to any single-source passive internal transducer system, like a Pure Pickup, FanTaStick, Twin Spot, or Big Twin. Simply attaches to the inside of the soundhole.
- Add-On for an existing pickup. Simply unscrew the existing endpin jack, remove it from the endpin hole, and plug it into the 1/4" plug of the Volume Control Add-On. The 1/4" plug has a self-adhesive fastener, which can be secured inside the guitar. The lightweight thumbwheel control mounts with a peel-and-stick installation to the inner edge of the soundshole. Mount the new endpin jack into the endpin hole, and you're done!
- This 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.
- If you're looking for a small onboard preamp solution that delivers more precise volume control plus a phase switch, we recommend the Pre-Phase Preamp.
