In the real world, the FM9 can dial in most anything I'd need.
In my fantasy world, I've tried recreating David Grissom's DG30 amp tone via utilizing a 2 amp 2 cab setup. I think although the result is nowhere near how DG actually sounds live, it's warm, wooly, and complements my DGT SE well. The preset gets loud, just like DG plays, but I'm reminded the DG uses his volume knob so that he's playing mostly full on during leads, and only backs off on his volume for dynamics and cleans.
In a totally separate fantasy, I've got Eric Johnson's tone pulled up with dual amps and cabs with a limited number of effects. The key is to get the sparkling cleans of a VibroVerb, and that gutsy saturation of a modded Plexi 100W, tube driver and/or Fuzz Face included.
In between these two fantasies, I've got lab experiments with lots of questions, theories and test kits.
I'd need to revisit John Nathan Cordy's YT vids and search for his RF mention with the FM3, if two fantasies weren't enough.
When someone can include a Ritchie Blackmore patch (say, for Lazy), I think I'd just about found the ideal tones of my attainable heroes.
Well, that and toss in Pete Townshend's Live at Leeds tone somewhere so I can reminisce about the good old days.
