12Pcs 27mm Piezo Discs with Leads Mic Drum Trigger Acoustic Pickup

I bought this set of YQBOOM piezo discs to experiment with pickups for various acoustic instruments, and I’m very satisfied with their performance. Pros: • Good Sound Sensitivity: These piezo discs are highly sensitive and pick up vibrations well. They work great on acoustic instruments like guitars and drums, capturing clear, resonant sounds with minimal distortion. • Perfect for DIY Projects: With 10 discs included, this pack offers a lot of flexibility for DIYers. I’ve used them to create drum triggers and pickups for CBG guitars, and they’re perfect for experimenting with different placements and configurations. • Sturdy Build and Quality Wires: The 3.94-inch wires are just the right length for easy setup, and they seem durable enough to hold up during repeated use. The discs themselves feel well-made and have handled soldering and installation without any issues. • Affordable: Given the quality, you get great value here, especially with 10 in the pack. Cons: • May Require Some Customization: Depending on your setup, you might need to add foam or adhesive backing for better sound isolation. Not a big deal, but something to keep in mind. Overall, these piezo discs have been a fantastic addition to my toolkit. They’re versatile, well-built, and work exactly as advertised. Highly recommended for anyone looking to experiment with contact microphones or DIY acoustic pickups!

These things are fragile, I was shocked to find that they were shipped in a ziplock bag rather than a box. In my case they were all in good shape but it really wouldn't take much to destroy them in shipping. I personally use these for auto bed leveling on my 3d printer and these work well for that purpose. The wires are a bit lacking but if you're careful and don't overheat the ceramic it's easy enough to solder thicker wires.

They work. But if you are using these for drums, well, I would do this for any application, put a drop of hot glue on the soldered wires. They break right there. Once I started using hot glue they did better. The wires are super thin!

These devices are very sensitive with a high output, the connecting wires are very thin, i added glue to the solder connections to give the joint more mechanical strength...would recommend

Exactly what I ordered delivered fast worked perfectly !!

I only needed one, but this is exactly what I needed to fix my RockBand drum set.

I repaired a Roland E-Drum cymbal by replacing the factory disc that went bad with one of these. Great price. Easy fix.

Used to replace a worn out sensor for a Roland CY-12C - it’s good but not as good as the original that came with the set. Could be that I didn’t install properly so may be a better buy if you are going to a professional But still, much better than the worn out old sensor

Half were broken on arrival. Others broke while manipulating…
