The story
Alex stumbled across an old handheld electret microphone, tried it on a few sources and ended up loving it on toms. As much as he loved those mics, he often couldn’t fit them around a tight drum set, so he took one apart, intending to rework the body into a 90-degree angle. Realizing it would make more sense to redesign the whole thing, he set out to create his own favorite tom mic, machined and built entirely by him, with all “audiophile” components.
The result is the Mario Mic: an electret condenser with very fast transient handling and an angled body, made for miking toms and snare drums.
