Bluepowder-
As for the Dyna Red...I don't really know how to describe it based on those few artists. Honestly speaking, I think it can cover all those grounds with a little tweaking, but to get the tone, it probably has to do more with the fingers. Especially with GNR/EVH, they use pretty little amounts of gain compared to the metal folks. It does the whole distortion thing very well, more marshall voiced than a dark mesa type tone. I think any dist pedal should cover those grounds perfectly fine, the tones you mentioned are not really as complex a dist tone as other artists out there eg. Lukather, Vai, etc. To me the Crunch Box does the EVH sound very very well.
But the thing which impresses me the most about the Dyna is that it does not sound at all like a pedal and more like an amp. You have to experience one to believe it. The distortion is HUGE, it's not hidden, muffled etc. It really sounds like an amp. I took a leap of faith and bought one, no turning back anymore man!
Jem2-
I'm sure your friend is enjoying the Murf as much as I am

I'm selling the ultimate octave to get a Chicago Iron Octavian. Not for the Murf though.
The Red Witch is a Moonphase, just the normal one not the deluxe model.
