Full interview with Kevin Killen, P G engineer from MixOnLine... http://mixonline.com/mag/audio_kevin...ing/index.html
"Do you remember how you recorded Peter's voice?
We used a tube 47. Peter always maintained that he'd used a handheld 57 in the control room on his previous records. Dan and I were skeptical, so we did a test. We set up a bunch of mics, and we blindfolded Peter and had him sing into each and tell us which one he liked the best. It came down to one, and he was sure it was the 57. When we took the blindfold off, of course it was the 47.
But there was a funny sound to that 47. It had much more air than you would normally expect-very pleasing sounding, but not as much bottom as you'd expect. We had our maintenance guy, Neil Perry, take a look and it turned out that one of the cables had a little nip in it. It wasn't getting full contact on the shield, and when he reconnected it back up it sounded much fuller-but the presence that we loved was gone. So we rigged up a system where we plugged the output of the mic into the patchbay, and we took the shield off a regular patch cord and used a mult of the two things; we brought the mic up on two faders to duplicate that sound-the regular 47 and the dropped shield version of it-and we'd balance between them.
What about the rest of the chain?
Peter had an old Decca compressor, kind of like an LA2A, very smooth, very slow. I set it up for a minimum amount of compression. I chose not to use a lot of EQ, mostly because I knew we'd be dropping in lines further down the road. We'd have EQ on the monitor side."
Hope this helps.
