mixmkr - sorry, just missed your post - we posted at the same time.
Thanks - yeah, that nails it - the hiss ain't my imagination. I'm using good mics, cables and pres. It ain't neighbor noise, cuz they don't hiss - they flush toilets and shit, and you'd hear that. I'm wondering if hiss can be generated by fields of electromagnetic radiation in a space, or something similar. Reason I'm thinking along these lines is because I thought low level room noise came across as rumble, not hiss.
Oh, yeah, almost forgot. The noise at 1.11 is the sound of my wedding ring rattling lightly on the neck while I'm trying to pull some vibrato out of that note. I liked it, so it stayed.
