I wrote up a build report for a Cortado – it’s over here, on my band blog. I was planning on modding it into a PZM/boundary microphone, but ended up needing this particular kit for a more standard purpose for a show coming up. The PZM project is still on the queue, though.

This is not the Cortado Tin Can microphone, though it has similarities, but it is Cortado driven. It’s a crystal mic, more of the sort you’d’ve seen in the late 1930s and through the 1940s, with a large front-facing diaphragm. (That white disc is a solid piece, and that silver “can” is actually metal-tape-lined cardboard.)
Version 3 (substantially improved) of the Cortado floating bridge pickup, an upgrade from the previous version above. Writeup and comparison sound samples here, but basically, the resonance plate now has a pressure chamber which you use with inserts to put pressure on the piezo’s crystal, and that changes the response profile a lot. Much less EQ needed in live use, which is a big usability win.
