OTraki Acoustic Guitar Passive Pickup, Stable Contact Microphone Transducer Self Adhesive Volume Control Piezo Picks, Easily AMP UP Pickups for Acoustic Classical Violin Ukulele Mandolin Banjo Cello

I bought this so I wouldn't have to cut holes in my classical guitar to fit an under saddle piezoelectric pickup system. It is one of my favourite classical guitars, cutting holes in the body, and altering the bridge and saddle could easily affect the tone, and ruin it. I had seen these Stick-on pickups before but didn't really think they would be any good without a pre-amp. However, I decided to try one, and this OTraki AD35 had good reviews and was reasonably priced. The setup instructions said to try it in different positions on the guitar front until you find the best sound. I didn't want to keep sticking and unsticking it lots of times, so I set my amp up with all the equaliser dials set to zero (centre) flat line. I then plugged the lead into the pickup and amp, and placed it on the guitar without removing the paper. I held it in place with a light touch of a finger and moved it around until I found a really good position. I was surprised at how different positions sounded, and I only had to move it a little at a time. I found a really good spot that gave a nice balanced tone on all strings just below the right end of the bridge (see photos). Any movement of 10 to 15mm in any direction from that spot, and the tone and volume dropped out! The placement was that sensitive and precise, so take the time to get it right. A note on the volume control on the pickup; I quickly realised that turning it up full caused lots of feedback from the amp. I found the best setting for this was just above the half way point, and it solved the feedback problem while still giving a surprisingly loud sound from my acoustic amp. I then peeled off the backing paper and stuck it in place. I have decided to leave it attached, and just unplug the lead when It's not needed. It's not in the way of anything, like changing the strings, and can't get lost or damaged by continually taking it on and off. They are cheap enough to get one for other guitars that need amplifying. The sound quality is excellent with a clear and balanced natural tone, and just needed small adjustments to bass, mid range and treble dials on my amp. It's perfect for now, and a bargain price. Only time will tell whether it is reliable or not. My only criticism is the 2.5mm jack plug and socket connections. The leads are hard to find if it needs replacing, and it would be much better with 3.5mm plug and socket. The lead is only about 3 metres long, and I used it with a 1/4" jack socket to plug 6 metre extension lead. So first impressions are very good. I will update this if I have any problems with it. It gets 5***** for now!

I have 2 guitars that need pickups, my Tenor (in picture) and a Dobro. I thought I’d try it out on the Tenor first. To be fair it works well but is very sensitive and makes a loud echoey bangs when caught by your hand or when you adjust the volume) so you need to place it where you won’t easily catch it. For the money it represents reasonable value, hence me buying a second for the Dobro.

Perfect, it’s really working fine in my home studio.

Wasn't sure about these as they were half the price of another stick on microphone I use on an old Harmony acoustic but for the price I bought two to try on other acoustics. I stuck one on just behind the bridge on my old Stella plugged it into the not so old but still old Peavey Classic 30 set the bass, treble, reverb etc and surprise, surprise it sounded great. I normally set the volume at halfway on the these types of pickup then adjust the volume on the amp to what I feel is right right luckily the neighbours were out. The OTraki is as good as the more expensive pickup I have and maybe even better as the volume is nicely hidden away on the side. This is my experience and I hope you have the same. God bless.

I used it on my soprano ukulele. First I thought it was a great product for the money, with great sound. But then I started to notice annoying string buzz, or total absence of sustain on some strings. I moved it around, then to another uke, then another one again. Now it seems to work OK on my concert uke with fluorocarbon strings. But unfortunately this nifty little device split open right in the middle of a gig. I guess that because it sticks so well to the surface of the instrument, each time you twist it in order to remove it, it weakens the contact between the 2 halves of the cabinet. It still works. I will superglue it and avoid moving it to another uke in the future. Also, if I need to move it, I will not use the sticky pads provided but something that is not so strong. Some reviewers mentioned Blue tac. I guess I will try that. All in all, it is quite a convenient device, but with a few flaws that one must know in order to make the most of it.

I'm a beginner guitarist and was looking for a way to add an electric sound to my acoustic for certain songs. This pickup has exceeded my expectations! It's incredibly easy to install – the included sticky pads make it a breeze. I was a bit worried about placement, but the instructions were clear, and I found the perfect spot quickly. The cable length is generous, giving me plenty of freedom to move around. Most importantly, the sound quality is fantastic. It captures the natural acoustic tone while adding a nice electric edge. I'm really enjoying experimenting with different sounds and playing along to backing tracks. £1 coin Is to give you a bit more of an Idea of the size of this device. Highly recommend this pickup to any acoustic guitarist looking to expand their sonic palette!

The receiver/mic did not function. I tested the lead through my amp with an adapter and the lead was fine but nothing. no sound when I plugged it into the receiver I had turned down the volume control to minimum as a precaution to start with and then turned it up slowly when installed there was sudden intense buzz and feedback followed by nothing. Im assuming the volume/impedance was faulty and blew the unit. its a cheap mass produced item so I expect they are not tested and get a lot of fails/returns. lets see if i get my refund ok, its a shame as i was excited to amplify my resonator but i guess i will have to spend £100 + on a properly rated under string (no hole) flat pick up.

It works really well and its very simple to use, however it's quite difficult to get it off my (glossy) guitar.

Il sistema è pratico, non invasivo, può essere collocato in qualsiasi posizione dato il piccolo ingombro. E' un buon prodotto, necessita comunque di essere collegato ad un mixer o ad un apli con un controllo toni efficace. Si consiglia di fare le prove di volume e tenerlo per tutta la durata dell'esibizione, in quanto risente del tocco e sfregamento e quindi regolando il volume si producono dei suoni fastidiosi.

Einfache Montage und funktioniert wie beschrieben einwandfrei.

Muy buena pastilla, da un muy buen sonido en tu amplificador. La he probado con una Admira de hace medio siglo, y suena espectacular. Muy fácil de poner, viene con una pegatina en su base que puesta, no se mueven y la puedes cambiar de sitio una vez probada en tu instrumento, girandola poco a poco y además trae unas 4 o 5 mas de repuesto dentro de la caja. Lleva un cable con una conexión a la pastilla, y en el otro extremo un macho/jack de 6,35mm (1/4") estándar para todo tipo de amplificadores .... Muy fácil de poner y rápido. Yo, la puse como está en la foto de Amazon, cerca de las cuerdas, en el puente (en la selleta o patín, como quieras) y se escucha bien. Tiene también una redecilla para darle más volumen. Aparte de lo que tu le des a tu amplificador. Si quieres algo así y bien de precio, prueba esta, te gustará por el volumen o transmision, pero sobre todo por su calidad de sonido.

Étonnant pour le prix. A voir dans la durée.
