Maybe not so "ominous." The suitcase is the carcass of a record player I found in the garbage. But this thing, I guess because it uses old Daka-ware knobs from HAM radios and has that stripped-down '60s test equipment look, feels like an ominous device - like a comic book version of something military and scary and suitcasey.
In any event, here is one of my more recent noisemaking matrices. I plan to upload and describe all of the technical details very soon. Follow for updates! Thank you.
haha thank you! :)
