I have to check this Ronnie guy out, never heard him. But almost invariably when I instantly like someone's guitar sound, I find out that it was pretty much straight-to amp deal. Angus, Cobain, Duffy, loads of examples. That is one reason I use FX usually pretty much only after-the fact in recordings.
