Buffered Contact Microphone (with Preamp)

A classic brass piezo contact microphone optimized with electronics. This mono mic requires standard 48v phantom power and terminates in a high quality male 3-pin XLR output. The low noise preamp built right into the piezo head lowers the impedance and provides 3dB of amplification giving you a louder, wider, more natural sounding frequency response. Made with 1/8" thick crystal clear shielded audio cable and 27mm brass piezo head backed with glittery silver or gold polyethylene. Lightweight, durable and moisture resistant. Unbalanced.

My best sounding, most versatile contact microphone.

27mm Brass Piezo Discs

These are the piezos I primarily use for my mics. They have an excellent frequency response that ranges from about 20 HZ up into the ultrasonic range. Because they're built with a brass resonating disc, they have a degree of self-resonance that produces a louder, if sometimes 'tinny' sounding signal which can be improved by damping. Make your own contact mics, drum triggers, speakers, switches, buzzers, transducers...
