Choptones does presets and patches for various modelers. Saw them from a video on YouTube. I have to say, after downloading some of their presets, I'm quite impressed.
They don't have a whole lot but, if you're looking for some good metal presets, you won't be disappointed.
It will be interesting to see what you guys think. Take a listen. Pretty good stuff.
