Sounds like it's from a Strat - correct?

I've experienced static electricity build-up on the Made in Mexico strat that I used to own and I solved it by backing the pickguard with copper foil, when I also shielded the pickup cavities with copper foil.

That sounds a bit like it, from what I remember back in the day. That was a little under 10 years ago when I bought that guitar and had the disappointing static build up and release, ruining some recordings.

Does it always sound like the very short snippet you posted, or does it change at all over time? Mac eludes to the whole signal chain. What exactly is the full signal chain from guitarist-->guitar-->....-->ZoomR16?

Also is that clip that you posted a .wav rendering from the guitar channel alone or is it from the Zoom R16 output mix-down of all of the tracks? I ask this because it also sounds a bit like an open cable that got recorded accidentally.
