15Pcs 20mm Piezo Discs with Leads Mic Drum Trigger Acoustic Pickup CBG Guitar

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!

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

Excellent seller and item

I used it to replace the piezo in my electric kick drum pad (Alesis surge mesh head kick drum). The wire on the old one got worn out because the beater was hitting the sensor too much. I had to adjust the height so it don’t hit the piezo directly. You need to solder the wires.

Alesis electronic drums break all the time. Very frustrating. Without these pizeos I'd have a $1,400 pile of garbage in my living room

They came in a loose bag like this with no protection and at least one was broken, others are scratched. While testing a pair one of the leads came free of the solder joint. I thought the wider size would have a larger pz surface, but only the thin backing metal is wider - it's a standard small pz. They're sensitive and seem to work ok otherwise.
