Been trying GTR3 for some time for recording, and the tones and stompboxes inside are pretty amazing. Just wondering, I know some keyboardists run VSTi's off their laptops during live gigs, but does any guitarist run their guitars off laptops during live gigs thru a processor like GTR3, or any other similar software amp/fx modelers (NI Guitar Rig 3, IK Amplitube, Alien Connections Revalver).
