K&K Definity System with Pickup & Preamp K & K

K&K Definity System with Definity Preamp.

The Definity System delivers K&K’s natural pickup power to a variety of difficult to amplify acoustic instruments in an elegant and easy-to-install package.

It is designed to work with virtually any floating bridge instrument, like Archtop and Macaferri guitars, and even semi-acoustic electric guitars with Tune-o-matic bridges. It is also well-suited for the banjo, cello, and many ethnic or folk instruments like bouzouki, saz, etc.

Installation Notes

One single pickup element usually transmits an entire instrument with good balance.

The Definity System comes with a stereo endpin jack (soldered mono) that allows for future upgrades. The endpin jack includes a self-adhesive clip that can be removed. It allows you to choose internal or external jack locations.

The pickup is only 6/1000 of an inch thin and measures 1 3/4” x 3/4” total. We call it a “compression pickup” because it is especially suited for “wedged” applications under a floating bridge. However, the pickup element is capable of transmitting sound like soundboard transducer as well. In fact, we found that the best tone is achieved if the pickup is mounted so it is partially “wedged” and partially open on the soundboard.

The Definity pickup reaches its true potential with a preamp. A basic solution is the Definity Preamp, which features a phase switch, adjustable mid and treble controls (via trimpots), and a 1/4” line out.
