ABOUT THE DEFINITY SYSTEM
The Definity System is a brand-new solution that 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. Check out the SOUND SAMPLES below.
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.
A more professional solution combines the Definity pickup with a Pure XLR Preamp. It features +/-20 db bass, mid, and treble controls, plus an adjustable input gain control. Its noiseless circuitry provides unsurpassed clarity and power and the adjustable input gain allows you to dial in the precise amplification factor needed for your instrument.
Definity played on a Banjo
This demo was recorded with a Johnson JB 070 open back 5-string banjo. It is a fingerpicked tune. No thumb- or fingerpicks were used. The Definity system went through the Definity Preamp. EQ was applied inside the Definity Preamp only and reverb was added. The tune is performed by Dietri and recorded in K&K’s recording studio on Cakewalk.

Definity played on a Maccaferri
This demo was recorded with a Cigano GJ-15 D hole Maccaferri guitar with 11 gage DaDario Maccaferri strings. A D’Andrea ProPlec 1.5mm pick was used. It consists of two tracks: a rhythm guitar and a solo guitar track. The Definity System went through the Definity Preamp. EQ was applied inside the Definity Preamp only and some reverb was added. The tune is performend by Dietri and recorded in K&K’s recording studio on Cakewalk Sonar X1 software.
Definity played on Ibanez Artcore
This demo was recorded with an Ibanez Artore guitar with 11 gauge nickel-wound electric guitar strings. We chose to demonstrate the combination of the Definity and the magnetic pickup. The magnetic pickup was recorded via a K&K Pure Preamp set flat and the Definity System went through the Definity Preamp. EQ was applied inside the Definity preamp only. A small amount amount of reverb was added to the final mix. The tune is a Joe Pass chord progression played by Dietri and recorded in K&K’s recording studio on Cakewalk Sonar X1 software. The first chorus features the Definity pickup only (right channel), the second chorus is the magnetic pickup only for comparison (left channel) and the 3rd chorus is a stereo mix of both.
Definity played on a Loar Archtop
This demo was recorded with a Loar LH300 traditional acoustic F hole archtop guitar with 12 gauge bronze-wound acoustic guitar strings. The Definity Preamp was used and EQ was applied with the controls inside the preamp only. A small amount of reverb was added. The tune is played by Dietri and recorded in K&K’s recording studio on Cakewalk Sonar X1 software.
Definity played on Semi-Acoustic Guitar
The Definity system is a surprisingly good addition to a semi-acoustic electric ES335 style guitar with Tune-o-matic bridge. It lends itself especially nicely to strumming. In this track we used the Definity System on a Hagstrom ES335 guitar. We optimized the Definity recording by applying minus 5dB EQ at 3500 Hz. For comparison, the second part is recorded with the neck humbucker via a K&K Pure Preamp, with +3dB at 9000Hz. The Definity System needed +10 dB of gain compared to the humbucker. We used a soft pick with a sharp tip. The guitar has 10 gage nickel-wound electric guitar strings.
