Egads, been waiting for this bugger for ages. There's loads of vst distortion effects out there (some top ones too -JCM 900, green machine etc), but nothing else has that 'stick a screwdriver in your speaker' bigmuff sound like this. Nice wide tonal range, and the 'edge' control really adds some nasty sleaze to the sound. Used in conjunction with some kind of speaker simulator, you can get that authentic 60s garage band sound off to a tee. Minimal CPU load (about 2% on my antiquated PIII 550), and a nice gui too. Cant knock it!
