The Joemeek suggestion is not a bad one. I picked up a copy of Mix or EQ, can't remember which, and read an article where Jack Joseph Puig talked about how he got the Gwen Stefani vocal sound (not that that's what you're going for) but he said it was a Joemeek with some Enhancer function used as a sidechain.
Found the link...here's the quote:
"Once when Puig mixed a record for No Doubt, Gwen Stefani came to him and asked him how they could create a vocal sound she heard in her head. “I sat and I listened to her talk about it and I imagined how I would get it,” says Puig. “And it ended up being that I got it using a Joe Meek compressor I had, which has a function called ‘Enhance’ that creates this very, very hyper top end that — for the most part — is pretty useless, but lots of times can also be great. It’s almost an aphex built into a compressor.
“When she went through the description about the vocal sound, I thought, ‘Maybe if I take the Joe Meek and actually use it wrong and way enhance the track in a way that you’d never want to use, then add it in as a side chain to the voice, then maybe I’ll get this top end presence thing she hears in her head,’” he says. “So then I did it, and it was great. Since then, it’s lived on my console, and on my console it says, ‘The Gwen Sound.’”
