TIMESETL 15pcs Piezo Pickup 27mm Piezo Amplifiers Discs with Leads for Acoustic Guitar Drum

Works well, good quality

Works as described. Solder blobs a bit big but doesn't affect performance

Very difficult to use - the wires are tough to strip, they cut very easily. If you do strip them, the strands of copper inside break easily.Best practice is to put them into a butt joint connector, or heat-shrink as soon as possible after soldering. The soldered joint on the actual piezo is also weak, and the wires will break away quickly if you wiggle the wires. A tiny drop of hotglue where the wire coating meets the solder can help add strength.I guess you can remove the wires and put on your own, however it is a small contact area to solder so it is very fiddly.For small projects the sheer amount of piezos this deal is just OK, but for something like a guitar pickup I would look elsewhere for a more robust offering with pre-soldered connections.

I haven't had a chance to try them yet. I purchased them in order to make my own head & rim triggers for electronic drums; or rather the conversion of a Ludwig Accent-Custom (2007) to a 7 piece e-kit.I'm sure they will work fine, I went with these as they had nice long lead-wires on them. I will probably reinforce the solder points with hot-glue. The lead-wires will be sleeved in shrink-fit tubing and the head-piezos themselves will first be 'sandwiched' between 2 pieces of 1mm foam rubber and then placed between two discs of 25mm diameter foam and affixed to the top of a L-bracket inside the drum-shell. These will then be connected to 1/4 stereo-jack sockets which mount through the drum-shell. All very minimalist. The drums themselves are concert-toms with very shallow depths.I may pick up the larger 35mm piezos for the shell-mount (rim-trigger) from the same supplier.

Kick drum pedal on electric drum kit wasn't working. Took it apart, had one of these in. Replaced it (with a little wire snipping and soldering) and now the pedal works perfectly and I have 14 more spares...
