I bought mine from Sweetwater in April before the new presets had been announced/released. When they posted the clips online I contacted my sales person (great staff there in my experience) and he managed to get me a zip file with the new presets; unfortunately, they didn't do a lot for me. I know so much of it is down to what type of guitar you use and what you are running through, but at least with the first bunch there were 5 or 6 that sounded ok with my stuff and I could tweak. The second bunch with the Satriani presets were a huge disappointment. Especially the Satch settings. They didn't allow me to surf with the alien at all!

So once again, as many have already pointed out, so much of it comes down to your guitar, and your touch, and the presets are somewhat secondary...
