Eh... some of the patches are OK. The artists patches come to mind, like the
Eric Johnson, Santana, or Pat Metheney. And a few of the patches have GREAT "unique" sounds, stuff you'd probably never invent. But for MAIN sounds, they generally are just so-so.
But who uses the stock patches?!

Certainly not me! I get great sounds out of it, but you'd better believe I edit the halibut out of everything, and get just the sound that I want. The GNX line is pretty darn versatile, with lots of editing options.
