## Description

The Pure Preamp is our time-tested external preamp, featuring +/-20 db bass, mid, and treble controls plus an internal gain trimmer. This belt clip unit has been specifically designed for the frequencies of the acoustic guitar but it is also great for many other instruments. The Pure Preamp features a special super wide band midrange filter, which is absolutely great in combination with the Pure pickups. Its simple and noiseless circuit provides unsurpassed clarity and power and the internal gain trimmer allows you to dial in the precise amplification factor needed for your instrument. Frequency response is 10-30,000Hz. The bass control is set to roll of at 100Hz, the midrange at 1.5kHz with extra large bandwidth and the treble are set at 10kHz. Input impedance is 1 meg and the output is low ohmic. Battery life is about 180+ hours.

Review: Fine piece of HW - I've had a K&K Pure Western pickup in my Gibson J45 for several years, and it sounded great all by itself so I never got around to buying a preamp for it. Recently I acquired a mandolin and wanted a pickup in that, so of course I looked first to K&K and selected their new 'Twin Internal'. This newer p/u seems to require a preamp, so I purchased finally purchased the K&K Pure. And it works great! My mandolin (just a Loar VS220) sounds better amplified than natural. And while I was very happy with the Gibson w/o a preamp, that also sounds even better with the preamp. It dawned on me a bit late, but this will give me more control over my own sound at the open mics I play at. I have had trouble with feedback and general boominess going direct to PA's in the past and am looking forward to seeing how much this unit helps there. The only thing I'm worried about is that the 9 volt battery just barely fits, and I'm worried I'm going to break a capacitor replacing the battery one of these years. After using for a month, an update. Don't leave a short cable inserted in the input source, it drains the battery. I see now that the KK website docs tell you this. Also, they could've done better with the way you access the inside to replace the battery. A slightly larger screw that you could turn with a dime would be the bare minimum improvement, but anything that doesn't require me to carry an extra, small slotted screwdriver around in my bag would be a step up.
Review: Must have for passive pickups - Love the size and the controls for volume and simple tone controls. My piezo pickup has never sounded better. I wish I knew about this little gem a long time ago. The other struggle I had was with the small headphone amps that plug into the guitar. They sound awful. Instead I bought a headphone adapter so that I can plug my headphones directly into the K&K preamp. Works/sounds great!

### ⭐⭐⭐⭐⭐ Outstanding acoustic instrument preamp--perfect match for k&k pickup
*by A***R on March 18, 2024*

Bought to use with a newly installed k&k pure mini acoustic pickup in an Irish bouzouki. Tried a couple of other preamps first, with mixed results. This k&k pure sound preamp was perfect. Full, rich, and balanced sound. Played first gig yesterday and performed flawlessly. Played with all knobs at 12 o'clock and sounded great. This is not a DI box, so no balanced XLR output, only 1/4" in/out, but I knew that going in. Bonus--it costs about half of what DI/preamp combos run. I would buy it again.
