Yeah but these are rarities.
Mark Day has some pretty amazing patches.
Dweezil is a saint in the patch sharing community in my eyes.
There are quite a few patches included. Examples are Rush, Van Halen, Randy Rhoads, etc....It seems people are finding that most seem to fit a specific artist with a small bit of tweaking. People are also gradually finding other presets that closely match other unrelated artist.
However, with such endorser's as Vai, Petrucci, Tabor, Broadrick, Thorn, and even bassist such as , dare I say (soon to come) Doug Pinnick?, as consumers, our pallets could easily be sated with down-loadable presets from these artists through a revamped and strategically well organized and articulated web page of some sort.
Simply my own opinion.
