KNAUP-1 Universal Stick-On Piezo Pickup – Natural Acoustic Tone for Guitar, Uke, Drums, Percussion, Easy Installation, Passive No-Battery, Compatible with Nearly All Acoustic Instruments

It worked very well with my Guqin (a rare Chinese music instrument) and the soundcame out from the amplifier is amazing, crisp, way better than an expensive mic. Why I didn't give 5star was the product quality: i put it on my instrument using the blue rubber provided with the pickup, after only a few uses, the thin layer of the cover separated from the body and fall apart, see the photo, I had to send it back to exchange. Not sure what's the problem but the craftsmanship should be better. Also the connection wire came with it is a bit loose at the insert, I had to replace it with my own.

Worked just as advertised

Putty doesn’t work. I used the stick pad and attached it to the bridge.Need a preamp with it.

I needed a couple non-permanent acoustic pickups that were relatively inexpensive. I purchased both an AP1 and a UP1. I am absolutely in shock and awe by how good these sound! I didn’t expect much from pickups under $50 since “the good ones” typically go for around $200. These KNA pickups blow away the more expensive ones I’ve tried. I might even use them for recording- they’re that good!!

it wouldnt stay together on the guitar or on the cord?? Junk

Nice & easy to use, using a pickup on my ukulele made it sound really good. It enabled me to get some really differ sounds playing it through an amplifier

Der Pickup wirde für eine UIkulele verwendet und tut was er soll und der Klang ist gut. Das mitgelieferte Anschlußkabel erzeugte ein lautes Brummen und musste deshalb ausgetauscht werden...
