Just stumbled on another free amp sim (vst 32bit); this one is from Wampler (maker of boutique pedals). I have been considering buying one of the Wampler pedals because they have gain, but they retain transparency; then I accidentally noticed their freebie--a vst version of their discontinued AC Cranked (an AC30 cranked).
 
The AC Cranked vst is found on the top right corner of this download page under VST Modelling: http://www.wamplerpedals.com/downloads/
 
Don't know if I like it yet; but it is free.

Cecelius,
 
Good find...
Smooth distortion, green screamer like. Beating the life out of Eventide upstream, Timeless downstream, and getting a realistic liquid overdrive.
It's a keeper. Thanks bro...

It's 32 bit only, and the dll is labeled "alpha".  Also, the GUI says "Powered by Le Pou".  I have heard some good things about their stuff.  Based on this plug, I think I will give them a look.

Haven't had a chance to run it thru the wringer yet! I downloaded it even though it is 32 bit. I'm trying to keep everything 64 bit but sometimes I can't help but sneak a 32 bit plug in there somewhere.
