I am going to gang up on Frank and agree with
Harry, Frank IS A GOOD GUITARIST.
To make the sounds he does when noodling brings out every thing needed to evaluate the Rig and
show cases how expressive/much dynamics are there.
Frank does little things to show the sweet spots in the rigs.
If thats not a Good guitarist then maybe every needs to go back to school
And i listen to my Elders like Harry 
Ash
Frank IS A GOOD GUITARIST.
Amen - nobody said the BEST 
There is no competition!
Got both of Guidorist's XTC profiles while I love, especially the new Merged pack. Today I grabbed the Dr. Z MAZ pack....wow! Amazing with a neck position single coil. It has to be a great amp that sounds sweet on that border of clean and dirty, just breaking up. This pack nails it.
Many THX!
I'm usually a DI into Ownhammer guy, but man Guidorist studio profiles are amazing !
Got XTC and Dual Rec. Needles to say I bought VH4 and PT20 an hour later. 
I think what sets them apart from many others is that he's a serious guitar player that knows how to dial in an amp. And I tried gigging with a lot of well known profiles.
Just my 2 cents, Guidorist rocks
