IMO OD2 does not have that marshall mids thing happening, kind of scooped sounding and more compressed. I love OD1 Orange and almost live there, can clean up very well with the fiddle volume and can go to hot rodded marshall. Colder pups really make it sound great as well.
I have a love / hate thing with od2, some days it is fun to screw around on but others it can be a buzz bomb. IMO OD2 can do a close Engl Powerball type thing.
