Wooh, another nice track. I would immediately buy your "Superpack" and I'm sure many others would do, too. I am more of a "conservative" sound guy, so a lot of the high gain and metal presets are not my cup of tea. Plus I play a strat most of the times and your presets sound like they could work for me as well (unlike most others).
So, please go for it! If you need help setting up a website to sell it, let me know (I am a freelance web designer).
