nope,it's not a modeling amp(at least,not that i remember).back about 3 months ago,i was at Randall Amps and was lucky enough to be taken into the "jam" room.Nuno's secret-prototype amp was there,in front of me,and it was in its final stages of production.i got a chance to plug in & play,for about 10 minutes.it sounded pretty mean and was like a "much-refined" jcm800'ish tone...
