15 Pieces - 27mm Piezo Disc Elements with 4" Leads - Acoustic Pickup Cigar Box Guitar CBG

These things are great. I used them to put pickups in 2 cheapo acoustic guitars I bought used for next to nothing. The guitars are great for playing pre-WWII style slide and the transducers cost about as much as I'm willing to pay for a pickup for them. I used some caulk like stuff to stick them under the bridge and wired them to a 1/4" inch jack mounted in a hole on the lower bout. You might try an impedance matching thingie for plugging them into an amp, but only to smooth out the sound. If you can solder you can get kits for next to nothing or roll your own from a circuit diagram.Bottom line: Not as good as a $200 pickup with a $200 DI/preamp. So mind numbingly cheap that you feel no guilt whatsoever installing them in a cheap guitar. Work great in resos too.

Can do lots of different projects with these and they came package well or at least mine did. Works great for repairing electronic drum kits and making pickups for acoustic instruments such as guitar or violin just to mention a few! They are cheap and neat to experiment with or just repair your gear.

Used these for drum triggers and the solder kept breaking. I've replace several so far and two failed while I was playing a gig. I tried using hot glue to support solder but that didn't do much good. Also the wire gauage is very thin. These would probably be better uses as pick ups for a guitar

Awesome product! Delivered a day early in proper packaging and works as expected. All discs were there, and were soldered consistently across the board. Tested all discs by attaching alligator clips to the leads rigged to a 1/4" jack output and ran a line to a drum trigger circuit and an amp circuit just to redundantly test them. Every piezo is kinda like a snowflake (just like valves/tubes and certain other components) but these I received were ultimately quite consistent across the board for impedance and passive output. You can't beat the price or quality/timeliness of service!

I made a guitar pickup with the first one, and it works great! I printed a compartment with my 3D printer and then encased the whole thing in hot glue and wired it to a broken 1/4" instrument cable. To stick it to the guitar, I used poster tack (putty). The case dampens the noise, but allows the vibrations from the guitar to be picked up. I have some other projects in mind, and I think these will do just fine!

15 is so many piezo discs! I used about 4 to add some acoustic tones to a Strat and they worked well. Now what do I do with the other 11? More guitar projects!

These Piezos are a great value and work perfectly! I needed to use them as sensors for a project with an arduino board. It was easy to strip the wires and connect them to a breadboard. Buy these if you need any piezo elements bought in bulk.

For the price it's really good, but some of the discs broke from the wires because the hot glue came out some how
