Personally I can't really recommend Tonex for anything (at least when it comes to dynamic playing), least of all for clean stuff.
My suspicion is that those who swear by it use a compressor in front of their amp-sim - something I personally would never do, so take my reply with that in mind.
Fwiw MGuitarArchitect is amazing for clean tones.
(Until recently I was - for years and years - a complete Melda nay-sayer by the way.)
