Sounds you can record yourself that translate well into 808s or other synths?
The other day, I whipped out the ol SM57 and recorded the "pop" sound that a pre-roll tube makes when you squeeze the sides to pop the lid off. It's a very clean pitched sound with a powerful transient that ranges all the way from 20hz to 20Khz fairly evenly, and a short sustain that has a strong fundamental with a nice blend of even harmonics.
I made a quick low effort beat out of it just to demo how it translates across the frequency spectrum, and out of everything, I was most impressed by its potential as a bass or 808 kick. (I'll link it in the comments)
I'm thinking if I re-record it at 96KHz it'll vastly improve the stretching potential. I didn't stretch it any more than FL automatically did to compensate for pitch, but I'm sure it would start to distort if I did.
So the topic is this: What are some other sounds that can be produced from (reasonably) easily accessible items, with surprising potential for sampling, either as an 808, snare, or anything else that sees frequent usage in our craft?
