In my wanderings around the net, I came across a board where the legendary gentleman who engineered Tom Petty's albums talked about what he used to compress TP's vocals. It, I believe, was a "Distressor".
When asked by a forum participant as to what settings he used ... and I'm paraphrasing from memory here ... he basically replied, "I twist all the knobs to the right." ... implying that compression was immediate, wicked squashed, and slow released.
Posters couldn't believe it. Such wild compression shouldn't sound good, they challenged.
"Works for me.", was the reply from the master.
... and so it goes ...
I got my RNC from my wife for Xmas last year ... and I use it primarily for vox. For my voice, I have to twist some knobs all the way to the right and some knobs all the way to the left. I almost exclusively use the "Supernice" mode.
... probably very weird settings, but hey ...
"It works for me."
