Description

Contact microphones allow you to pick up vibrations and convert them into sounds! Capture a whole world of AMSR sounds that would otherwise go unheard!

These handy little Piezo contact microphones are small metal tin that house a high quality 27mm Piezo wired to a robust high quality 3.5mm Mono Jack socket.

The disadvantage of most contact mics on the market is that the fixed cable is prone to damage but thankfully with our design you can swap the cable! This also makes it much easier to use as you can choose a suitable length of cable to suit each situation.

The case is thin and flat to allow for good contact with other surfaces for efficient transfer of sound waves to the Piezo element. To permanently fix it to materials use double sided tape.

For an example of what it sounds like here’s a recording made by Holly Burrows of her cat purring.

For best results use a shielded cable and keep away from interference sources like mobile phones and motors.

Piezo microphones work best when used with a piezo pre-amplifier or a high impedance (high Z) input on a mixer or recording device!

Beepboop make a portable and rechargeable contact mic amplifier which can be found here.

If you want to get sounds directly into your Eurorack system for recording or processing I also make a 2hp Kontact Mic amplifier module designed to amplify the signal up to Eurorack level! (link below)

Things to try!

One very interesting application is to pair one of these contact mics with a transducer. With the two, some amps and mixers it’s possible to make you very DIY plate reverb!
