KNA UP-1 Universal Stick-On Passive Piezo Pickup for Acoustic Instruments
Safe and secure checkout
The KNA UP-1 is a compact, lightweight stick-on passive piezo pickup designed to amplify a wide range of acoustic instruments without permanent modification. It attaches safely to the soundboard or vibrating surface of the instrument, making it a practical option for players who want a simple amplification solution that can be fitted and removed easily. It is designed for use not only on guitar and ukulele, but also on harp, drums, and percussion.
One of the biggest strengths of the UP-1 is its portability. KNA describes it as their lightest and smallest surface-mounted pickup, with a passive design that delivers natural acoustic sound without needing a battery. That makes it well suited to players who want an uncomplicated way to plug into an amp, PA, or acoustic preamp for live use, practice, or simple recording setups.
The pickup is housed in laminated birch with a mahogany top, giving it a more refined look than many basic stick-on pickups while keeping the weight very low. It also comes with installation accessories that allow repeated fitting on different instruments or positions, which is especially useful for players experimenting with placement to find the best sound.

Why Choose This Pickup?
The UP-1 is a very useful option for players who need quick, non-invasive amplification. Unlike fitted undersaddle or internal pickup systems, this one can be attached with no modification, which makes it especially attractive for folk instruments, smaller acoustic instruments, percussion, or any instrument where permanent installation is not ideal.
It is also a good choice for musicians who want to keep their setup simple. Because it is passive, there is no battery to worry about, and the included detachable cable means the pickup can stay mounted while stored more neatly between uses.
For shops, this is a handy product because it appeals to a wide spread of players: acoustic guitarists, ukulele players, harpists, and percussionists looking for a quick way to amplify their instrument without drilling, soldering, or permanent fitting. That broad compatibility is an inference from KNA’s stated use cases and installation method.
