Unique-Bargains 20 Pcs Piezo Discs 10mm Brass Transducer Pickup

SKU CH-KV0H-5TEG9

A pack of twenty 10 mm brass piezo discs with 40 mm leads for building acoustic pickups, contact mics or stomp boxes

  • TypeGadgets
  • 20 discs provide plenty of spares for multiple instrument projects
  • 10 mm brass elements deliver clear acoustic pickup response
  • Resonant frequency 3.0~5.0 kHz captures detailed vibration nuances
  • 40 mm pre-attached wires simplify solder-free installation
  • Low 300 ohm impedance ensures efficient signal transfer with minimal power loss

20-Pack Piezo Discs for Acoustic Pickups

This pack contains twenty brass piezoelectric discs designed as transducer elements for acoustic instrument pickups. Each disc measures ten millimetres in diameter and 0.3 millimetres thick with a 40 millimetre wire lead. The components suit builders creating contact microphones, stomp boxes or custom pickup systems for guitars and drums.

Resonant Frequency 3.0 to 5.0 Kilohertz

The resonant frequency range of 3.0 to 5.0 kilohertz with a maximum impedance of 300 ohms determines how the disc responds to vibration. This specification decides whether the element matches the tonal character and signal level required by a particular preamp or recording setup.

Brass Elements with Short Wire Leads

The brass construction provides conductivity and durability while the 40 millimetre wires need extension or direct soldering to reach a jack or circuit board. No housing, shielding or mounting hardware is included so the builder must supply enclosure, strain relief and any impedance-matching components the design requires.

Questions about this item

What does the 3.0~5.0 kHz resonant frequency mean when the disc is glued to a guitar top?

The disc responds most strongly between 3 and 5 kHz, so it captures the bright attack of steel strings while rolling off lower body resonance.

How does the 300 ohm maximum impedance affect the signal into a preamp?

The relatively high impedance requires a high-impedance input — typically 1 megohm or more — to avoid loading the disc and losing low-end detail.

Will the 10 mm brass discs fit inside a standard acoustic guitar soundhole brace?

At 10 mm diameter and 0.3 mm thick they slip easily under most brace feet, and the 40 mm leads reach a nearby jack cavity without splicing.
