I used this KNA UP-2 pickup on a clay pot drum and it sounds incredible!I am surprised at the wide range of frequencies it is able to pick up.The volume control on the pickup is extremely handy and enables me to really dial in the sound.It adheres to the surface of the drum easily.The instructions are straight forward and easy to understand.The wood finish of the pickup is aesthetically pleasing and looks great on the my instrument.It is at a great price and I plan to buy another one.

Great sounding, pick-up for ukulele, great size, volume control is a plus, portable and affordable with plenty of "punch". Mounts and removes without marring or damaging instrument finish. A great accessory for anyone wanting or needing to amplify the instrument through any amp, pedal, or other filter. It will be useful on gigs and to just have fun with experimenting with electronics I use with my guitar which is now possible with my ukes and not requiring drilling holes, running wires, and tightening bolts and screws, or having to adjust bridges. Probably works well on all size ukes and other acoustic instruments. Without question -- WORTH HAVINGDr. JWG

The adhesive sticker they give is a bit thick which causes the pickup to only catch it when you play loudly. The putty was as hard as a rubber eraser but warm water did do the trick like they advised. The putty did a better job at picking up sound than the foam sticker, but it does not stick very well. I might just use some super glue to attach this so it can pick up on sound better.For the price, it really isn't bad. The gain knob does not perform well with the foam sticker because of the sound dampening. Still though, I'm happy for the price point and it will do the job. It's hard to find an acoustic pickup for a sitar lol, and finding the right placement was easy with the putty allowing me to move it around until it was optimal.Might order another for my other acoustic Asian instruments.Definitely looks nice too, found it looks like it was meant to be on the sitar with that nice lacquered wood look.

The reason I gave it just 4 stars is because the glue on the back came loose. Not the glue to the surface of the instrument, but the glue to the back of the pickup itself would not hold under any load. I finally got some wood glue and glued the pickup to the sticky pad. I hope this makes sense. Otherwise, It works well, and gives a good tone.

I have used the KNA pickups on a couple of my ukuleles, and I really enjoy the quality that they provide, as well as the easy install. The size of a contact pick up is really important - you don’t want your hand to hit it while you’re playing, which can create a lot of unnecessary noise.The price on this item is just right, not too expensive, and definitely not a cheap flimsy item. It fits onto any acoustic instrument, though I’ve only tried it on Ukulele.It uses a contact putty, which I’ve never had an issue with, but for some reason with this one, I was having trouble getting it to stick (it’s fine now) and I pressed a little hard, and cracked the device a little bit in the process, before I had ever used it. My heart sank because I felt so stupid, and I know I love these pick ups!Upon using it, no issues! I didn’t break it nearly to the point I thought I had, and don’t have any issues plugging in the cable to use it.A great option for any acoustic instrument with no electric capability, highly recommended!

Works great, however the volume has a tiny hum or buzzing sound unless it's on the high setting. You probably wouldn't hear it on stage, but you might hear it if you were using it to record something.....That being said, I always use it on the high setting and I use the knob to either turn the volume on or off. On the high setting it has a wonderful & clean sound. Coupled with my Fender acoustic 100 amp, it's a great combo. With all that said, I ordered a second one! Update...The cable that comes with it is 10ft not 8ft. 10 is actually better!

It works great without having to modify my guitar, sound is nice and strong (it is practical that it has a volume control on it), different positions on the guitar get different sounds. I love that it is covered in wood complementing nicely my guitar.

It does work and is adjustable however I can touch it or talk to it and it registers noise. Just touching the instrument almost blew my speakers. I would recommend not using any Piezo mic, If you can not add a pick up then buy a new instrument. For my Autoharp it will cost 99 to buy and 150 to install not counting shipping to and from the installer.

Öncelikle ben klasik gitarım için bu ürünü aldım. Ancak ses performansını açıkçası beğenmedim. Gitarınıza monte ettiniz ve amfiye ya da ses kartınıza bağlandınız diyelim. Bir kere ses gitarın kendi sesi gibi asla değil ve oldukça cansız. Aynı amaçla kullandığım irig acoustic stage'in yanında mukayese bile edilmez. Keşke Acoustic stage'i daha önce alsaymışım. Diğer bir sıkıntı da kablosu. Kablo çok kalın. Çalım performansınızı etkiliyor. Ancak hiç yoktan iyidir manasında çaresiz bir durumda kullanmak üzere dolapta duruyor. Hani fiyatı uygun olsa f/p diyeceğim ama öyle de değil maalesef.

I did a lot of review reading on various pick-ups and decided to try this one and I am so happy that I did! Great sound and really great quality craftsmanship. I have a couple of acoustic guitars that I have never wanted to have holes drilled into or things placed into the sound holes and this pick-up totally does the trick perfectly. My acoustic guitar sounds full and the tone is really lovely.

No transmite demasiada señal, yo opté por pegarla directamente a la caja de la guitarra, probando antes varias localizaciones hasta colocarla junto al puente y así sí funciona bien.

Super leistbarer pick up mit super sound! Habe ihn an meiner mandoline montiert und der tin wird super aufgenommen (einfach in der nähe der brücke montieren, egal bei welchem saiten instrument)Das gute bei diesem pick up ist das er einen volume knopf hat womit man die lautstärke zusätzlich einstellen kann damit der sound gut klingt.

当然ですがそのままでは信号が微弱すぎるので、ピエゾ専用(最低でも入力インピーダンス1MΩ)のプリアンプ等は別途必要です。私はtc elec.のBodyRezにそのまま挿しています。出音はとても自然で良いと思います。聞いた感じ不自然なピークは無く、ダイナミクスも充分で、信号として扱いやすい感じです。マイク面が白木のままでコーティングしておらず、かつ薄くなっているので、あまり粘着力の強いテープを使うと剥がす時に壊れそうです。付属のテープはちょうど良い粘着力でした。私はマイク面を水性ウレタンニスを塗って補強しました。木で作って可能な限り軽くしようという気合いは好印象ですが、それでも貼る所によってギターの生音が悪くなってしまう(弾いていて全然気持ちよくなくなる)ので、貼るのは生音を損なわない位置で妥協しておいて、出音はイコライジングして整えるつもりで触るのが楽しいかなと思いました。
