Nice problem to have! On the strength of nothing more than a spectacularly popular Instructable, we are nearly sold out of Cortado Balanced Piezo Contact Mics. We have parts on order for a second production run (double the initial run). We will “officially” launch the product the day the last of the parts arrive. You can certainly buy a Cortado in the meantime, but just know: if you don’t move quickly, your mic may be backordered for a week or two.
