for Acoustic Bass Guitars (also works for Tenor Guitars)
This specialized, easy to install transducer system does not sound as harsh and is less percussive than saddle transducers! By positioning transducers directly beneath the bridge inside the guitar body, high signal-to-noise ratio and high gain-before-feedback can be achieved. In addition, the guitar top plays a more important role than with saddle transducers, yielding a warmer, more microphone-like tone. The Pure Western (shown), for steel string guitar, has three transducers. The Pure Classic, for classical guitar, has four transducers to allow for its different bracing pattern. The Pure Bass/Tenor Guitar has two transducers (the five-string version has three). It is the bracing and number of strings that should guide your selection; e.g., the three transducer Pure Western model should be used for a five string acoustic bass guitar.
The Bass/Tenor Guitar four string model is shown in the illustration (see images, above), which demonstrates where the transducers are located. Installation is far easier and precise positioning is less critical than with the typical undersaddle transducer. Special tape is included to apply to your precious instrument's soundboard, so you don't need to superglue the transducers directly to the wood - removal is easier and the installation is non-destructive. The special tape and a tube of Super Glue are included, and the transducers are prewired to a high quality endpin jack.
K&K Sound, manufacturer of the Pure Guitar system names the following ADVANTAGES of the PURE GUITAR's transducers and mounting system:
- The special PURE surface transducers DO transmit a significant portion of the soundboard because they are not as close to the strings as an undersaddle pickup. Each of the transducers is designed to pick up a specific string pair, but also “listens” to the adjacent area around the bridge.
- The PURE pickups are not under pressure and therefore do NOT sound percussive or harsh.
- The PURE system reproduces all strings nicely balanced, a known problem with undersaddle pickups.
- The PURE system sounds great just in passive mode! Unlike undersaddle pickups which passively sound thin and treble-only, the passive PURE system puts out a nicely balanced, warm, full range signal.
- How safe is the PURE GUITAR System with feedback? Due to PURE GUITAR’s location on the bridge plate under the bridge, feedback resistance is comparable to undersaddle transducers. Technically, a pickup installed in or on the bridge is a lot less likely to feedback than one which is attached to the open sound board. The 1/8” thin sound board can act like a diaphragm and vibrate along with loud sound-signals from speaker cabinets. This is the kind of feedback you experience on an acoustic guitar. The thicker bridge area is a lot harder to be set into vibration from an outside source simply because of its mass.
- In K&K Sound's tests with both steel string and classic guitars equipped with an undersaddle pickup plus the PURE system, they were able to achieve about the same gain-before-feedback with both systems.
Disadvantages of undersaddle transducers:
- Hard, percussive tone, because the piezo transducers are under high pressure.
- They picks up mostly string and finger sounds, and capture very little from the guitar's soundboard, so crucial in reproducing your guitar's true voice.
- There is always the chance of unbalanced volumes, with individual strings louder or softer than others. Trying the equalize loudness can result in a very work intensive balancing procedure.
- Needs special preamp to compensate for the hard sound.
Of course, every manufacturer swears that his undersaddle transducer is far better than anything else. Let’s face it, as long as the pickup is in the undersaddle position, they have to deal with the above mentioned characteristics.

pure bass 4 string pick up
I had never installed my own pick up before and I found it pretty easy. I have an 85 Guild B50 with a compensated bridge and my end pin had already been drilled to 1/2" from a previous pick up that had been removed. Its a perfect solution to the compensated bridge issue. I dove right in and used the gel super glue method to glue it directly to the bridge mount since it said you'll lose 20-30% of the volume with the provided strips to glue it to. I just plugged it into my old Ampeg B15N and was stunned. It sounds fantastic! It doesn't need a preamp for volume. It has very good tone and needs little EQing to get the sound right AND NO BATTERY to mess with. I have some gigs coming up. I can't wait to try it out there. I can tell by the way it sounds through my amp it's going to be great through a direct box into the PA. It's great choice for an acoustic bass and Gollihur is the cheapest and best place to buy it.
K&K Sound Pure Bass Pickup - for Acoustic Bass Guitar
The issue I was originally looking to overcome was inconsistent volume balance between strings to the point amplified playing was not feasible. The K&Ks solved that problem and the sound quality is for my needs dramatically better as well. At reasonable volume, I can get a pretty awesome sound with any of my amps or going straight into the board. Beefy, three dimensional, and driving with a nice "wood" timbre. Thanks again for the great support, encouragement and hand-holding along the way; I'll highly recommend you guys if ever the opportunity presents itself.
K & K Pure Bass Pickup
I installed the Pure Bass pickup in my acoustic bass guitar. Wow, the sound is fantastic and is a great reproduction of the guitar's non-amplified sound.
Gentlemen: Thank you for the above order for my Blueridge Tenor Guitar. I followed your precise instructions for placing the (2) pickups under and between the C & G and the D & A strings using the tape you sent me and not using super gel glue at all as stated by your representative and it worked just beautifully. When finger picking this truly brings out the quality Bass and Treble notes of this instrument fully. I play Tenor Banjo mainly and truly appreciate the true quality tone that this guitar can produce with your K & K Sound Pure Pickup for 4 string ABG or Tenor Guitar. I would recommend this pickup to any serious Tenor Guitar player.
Full harmonic range
I finally had that K & K Pure Bass pickup installed in my Dean acoustic. Man, what a world of difference. Instead of that pinched nasal tone, I’m hearing the full harmonic range of the instrument, much closer to a “pure” acoustic tone. Plus, as you said, they were able to hack into the existing preamp no problem. The work was done by a local luthier for me. Thanks for steering me towards this equipment. The Dean is now a formidable bass in my arsenal!
