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! Review: Cheap but the packaging is very lacking - 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. ## Features - Great for Acoustic Instrument Pickups, Stomp Boxes, Contact Mics, Etc… - Primarily used in acoustic guitars, CBGs, drums, and contact microphones - 20mm brass outer diameter plate, 100mm leads - 20mm Frecuencia de resonancia (kHz):5.6+/-0.5 kHz ## Technical Specifications | Specification | Value | |---------------|-------| | Best Sellers Rank | #5,113 in Musical Instruments ( See Top 100 in Musical Instruments ) #7 in Guitar Pickups & Pickup Covers | | Customer Reviews | 4.5 out of 5 stars 425 Reviews | ## Images ![27mm Piezo Disc Transducer Contact Microphone Trigger Sound Sensor - Image 1](https://m.media-amazon.com/images/I/81BejdcBGyL.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Quality and Versatile for DIY Instrument Projects *by J***D on November 12, 2024* I bought this set of YQBOOM piezo discs to experiment with pickups for various acoustic instruments, and I’m very satisfied with their performance.

Better if you glue the solder so they don't break *by S***. on January 28, 2026* 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! ## Frequently Bought Together - YQBOOM 15Pcs 20mm Piezo Discs with Leads Mic Drum Trigger Acoustic Pickup CBG Guitar - TIMESETL 15pcs Piezo Pickup 27mm Piezo Amplifiers Discs with 13" Leads for Acoustic Guitar Drum - DZS Elec 15PCS 35mm Piezo Disc Transducer Contact Microphone Trigger Sound Sensor with 4 Inches Wires for Acoustic Instrument --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.be/products/67130537-27mm-piezo-disc-transducer-contact-microphone-trigger-sound-sensor](https://www.desertcart.be/products/67130537-27mm-piezo-disc-transducer-contact-microphone-trigger-sound-sensor) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-09-29*
