TIMESETL 5 Pcs Piezo Contact Microphone Pickups Self-Adhesive Instrument Pickups for Guitar, Violin, Viola, Cello, Banjo, Ukulele, Mandolin and More

This Pick Up (in a Kit of 5 each) has worked excellently for me.I build harps for a living. I bought a set of these to try in my harps, to be used for tuning the many strings of a harp. These brand Pick Up has worked perfectly. I plug my higher-quality electronic tuner into the 1/4" jack of the Pick-Up and I can tune every single string, right on up to the harder to detect high treble strings!This is no common feat. Even the best of electronic tuners, whether using their open-air microphones or external clip-on pickups traditionally have a hard time when it comes to working well on harps. They will often miss the notes, especially the high treble notes. Or, you have to continually pluck a string for the tuner to eventually register. And, that is an issue when one is tuning anywhere from 22 to 40-something strings at a time every day.So, I was excited when this pickup allowed my electronic tuner to detect every single note, at every single pluck of each string the very first time. This has greatly improved my tuning accuracy while cutting down my time quite a lot! I was so enthused about this Pickup's performance I thought I should write a good review for it, which reviews I never usually take time to write.I have not yet tried it in my Bose portable line array sound system to see how the Pickup might perform on a sound system. When I do, I will write another review. What makes this Pickup so good is on one of my larger harps, I have a very expensive dual pickup system mounted to the harp's soundboard and it doesn't work as well as this single unit nor does the dual-pickup work with any quality on my Bose sound system (very noisy and inefficient).Thus, I highly recommend this unit for harp players and makers. For sound system performance, the jury is still out on that one. As I wrote above, I will test this and write another review.

Whether it’s $100 or $3, a piezo is a piezo. And this is a piezo—but like, “buy one, get four free.” You can’t go wrong. Captures every nuance of my upright bass. Peel and stick, right to the bridge. Velcro’d the jack to the tailpiece. In business in under a minute. Love it. Plus, I have four of these left over. Hmmm…UPDATE: After experimenting with placement some more, I actually like the sound better when it's stuck directly to the top of the bass, in line with the bass bar/bass-side bridge foot, about 3/4" toward the tailpiece (approximate mirror image of the soundpost position on the treble side).

I picked these up as an amplification solution for my kalimba. Instead of buying one for $10 elsewhere, I went with five for $15 here. So far, I have no regrets! The adhesive sticks very well to the back of my kalimba (I haven't tried removing it yet), and the sound is great. The amp jack on these is very tight, so be sure to push in the plug ALL the way (don't be afraid to get tough with it). Also, the wire feels pretty thin, almost like it could break, but I have four spares just in case, so I'm not too worried.If you need a simple and cheap way to add a contact mic to something, these mics are a good solution!

Works like a charm however at first it might seem like it's not connected but it comes back within minutes and has a nice threshold for pickup. A+++

Well, it is capable to amplify the resonance of my LP Mini Conga sound box. Not at a great quality but just enough for some special needs. Usually I practice with this instrument but in my presentations I use a real Conga set. Sound quality is acceptable and with some metallic frequencies. Like the effect you get when using a small speaker. For the price and units received for it (5), I have no regrets. If you're planning to amplify any music equipment with this pickup unit just keep in mind that is just for room presentation, practice or casual events where you do not want to carry a lot of equipment. For bigger events or presentations I recommend more professional equipment. Another good quality is that is not permanent. You don't need to make perforations to your instrument that could damage it. Is a plug and play thing. Easy to remove. On my case the best sound is produced connecting it directly to the speaker. You can try it with a mixer too to get better sound.
