Self-adhesive Pickups Piezo Transducer, 3 in 1 Microphone Contact & Endpin Jack 1/4" for Electronic Acoustic Guitar Violin Ukulele

The product arrived from one day to the next. It came in a cushioned envelope. Upon opening it I noticed one of the piezos had broken white film-it was chipping away, the soldering was intact though. I had a decision to make- keep it or send it back??? For the price and having passed the test (hooked it to an amp to test it) I kept it. I reamed out my guitar endpin hole to 1/2” with Stewmac reamer I bought here on Amazon a couple of weeks back (along with some smaller drills to start the hole) I had the piezo installed in my classical guitar in no time. The threads on the jack can get cross threaded so don’t force it. As far as placement for the three piezos I just somewhat evenly spaced them just forward of the bridge ( similar to the K&K model) as best I could, my guitar has bracing. The piezos have 3M adhesive that work well I slightly tugged under the base of one of the piezos(not by the cable) and it was on there. So once you put them on you might not be able to move them without something damaging or falling apart. I then stuck the zip tie with the other base to hold the cables. Sound wise, I used a Fender Mini passport, the amp has different presets I simply found the best one that worked. I found in some cases I had to really blast the volume and in some cases there was too much volume(depending on preset). I did use a feedback buster(soundhole cover) but in some cases I still got some feedback. In my setup there was to much bass not enough mids or trebles ( results will vary depending on placement of piezos) and of course volume was controlled from the amp. I play at church but I think this pickup will only be used at home to jam and practice. All in all it was nice to electrify an old Yamaha classical guitar. For what it is and the price, I recommend it.

for the price i think they are well worth it.. very simple install and set up.. i used these in a homemade 'guqin' and mounted them under the 'sound board' of a piece of clear heart redwood i've had for over 25 years; seasoned perfectly.. in a guqin, you hollow out a thick board until the top is only 1/4" and sides are 3/8"; then a much denser piece of wood is used as a bottom.. the bottom has cut outs for it's 'sound holes'... the guqin is a quiet instrument and this set of pickups plus a fender acoustasonic amp helps out a great deal ... well worth the price....

We installed this kit in my concert size ukulele. The sound is loud and now I can rock out! My husband was about send the kit back because we couldn’t figure out how to thread the jack through the hole because it looked impossible without having super long skinny fingers. We took a length of heavy wire (like a coat hanger) and taped a paper clip to it. We hooked the paperclip through the little hole in the jack and pulled it through the hole we drilled in the uke and it worked great! We found a video on YouTube that showed a guy installing a system similar to this one. I attached the piezos behind the bridge.

Adhesive backing was near impossible to remove, jack was difficult to plug a 1/4 inch cable into, and it didn't work once it DID plug in. Not happy with my choice. I try to not let negative reviews factor into my purchases, but I really should have with this.

Easy to install, but sound quality is very much on the treble side. Turn up the bass on your mixer and it should be fine though. Also, watch videos to see where to place them. I think under the bridge works best.

I bought this so I can mix guitar and vocals and "play along" music while practicing. It wasn't too hard to install, but takes some thought. I did find that after playing for a bit, the endpin wanted to come loose. I used a few red threadlock drops and it's been tight ever since. The sound is pretty good. I mounted two piezos onto the bottom of the bridge (one on the "treble" string side and one on the "bass" string side) and one to the body just in front of the middle of the bridge. I just use the preamp on the mixer and it's a good mix. I suspect that a dedicated preamp would sound better, but for what I need it's surprisingly good with really no buzz. EDIT: still going strong after almost a year and a half. I just got a Behringer ADI21 pedal, which is about $35 and it makes this pickup set sound amazing. So for less than $50 all in, I have a VERY nice sounding cheapo guitar. FYI, this is mounted in a Jasmine S34C, which is incredible also for the price.

I installed it on my banjo. I thought it would be smart to stick one disc underneath where I strum it…bad idea! The scraping of the strings and tapping of my strumming hand on the banjo head really stuck out. I pulled off that disc and cut the wire as it was SUPER hard to pull it off and bent the disc and broke its wire lead. No matter. There were two left under where the bridge sits and the cut off lead did not buzz. The sound is pretty darn good now! There are better sounding piezo pickups, but they cost a lot more than $10! The female jack is big and beefy. I am not worried about it breaking over time. The screw on cap makes it look very nice, like my banjo came with this from the factory. I highly recommend this pickup. Excellent value!

I've built 7 cigar box instruments, from a tenor uke to a 30 inch scale bass. I like this piezo setup--cheap and sounds ok by my troglodyte tastes. The sound is better than the single smaller piezo products, about equal to a product from CB Gitty that has a bigger piezo, but it's downside is that it comes with a volume control that didn't work. This thing works. The toughest part of this product is how big the hole for the plug has to be--dern big. But the plug is also more substantial than other cheap options. All in all, this is my favorite for cheap parts for cigar box stringed instruments. One tip that someone posted and that works better--with a hot glue gun, lay down a layer between the box and the piezo, this cushions or tempers the clanginess of the amplification. Tons of hot glue works.

I use them on an upright bass and they are ok! A little experimenting helps in terms of placement, so use doublesided tape to find out where before you pull the adhesive backing off.

No installation instructions, however, found installation instruction video on Youtube which assisted. Sound is quite good and "chorus and reverb" are effective. All in all, this amplifier is worth the price,

Didn't hold in place, have to clean the self-adhesive and use glue. NO complaint , sound is nice and true ! JP

Not overly fussy about this product. The set up to engage the jack into the receptacle was off just enough to miss the connection necessary for function. Im trying to reset the distance the jack can go in, but there's only so many threads on the finish button... doesn't seem to wanna work with me. If it happens with the second one I got... I'll send it back.
