To make the contact mic we used 35mm Piezo discs and attached them with a soldering iron to a 6.35mm jack, using the 6.35mm jack was very helpful as it could be connected to a field recorder or to an interface easily without using an adapter. The process was relatively easy and I was scared at first to use a soldering iron as I haven’t before and thought I would solder too much by accident but this wasn’t an issue. I really enjoyed making the microphone and it has lead me to start getting into building guitar pedals and eurorack modules as I now know how to solder and have been reluctant to in the past.
