Studio Project: Slinky & Contact Mic

One of my current projects called for some experimentation with a miniature Slinky spring. For years it's been part of a lo-fi spring reverb that I built, which never worked very well (it needed a preamp).

So, a few minutes with some rubber bands, two microphone stands, some painter's tape, and a buffered contact microphone et voila:

I hooked it up to my ART USB dual preamp, but found better results with the Arctic MC6002 mixer. I filmed some short clips using both setups so you can hear the difference:
