tube preamp VST plugin?

["Krispen Hartung" <khartung@cableone.net>]

While I'm lucking out with such great suggestions from the group, can 
anyone 
direct me to a free and decent tube preamp VST plugin? I run my electric 
guitar directly into my laptop and want something to give it a bit of a 
warm 
tube preamp feel. I don't need anything complicated that eats up a lot of 
processing, emulates tons of amps, distortions, speakers, etc. I'm 
basically 
searching for something that will give me a nice clean jazz amp feel....a 
bit spongy, not boxy, sterile, or distorted, just warm and clean.

Too bad ProCo doesn't make a Ratt vst. Or better yet, can someone write me 
a 
Mesa Boogie Triaxis VST plugin? :)
