I'm sitting in a hotel bar right now in Helsinki, about to go back upstairs and practice some "Thunderkiss '65." I bought a Stealth Plug from IKMultimedia, and am running Amplitube3 on my laptop. I carried my GLP studio onto the plane, and it fit in overhead nicely. Amplitube took a while to dial in, but for roughly $100 bucks total (not including guitar or laptop) I have an amazing variety of sounds and recording capabilities.

Of course now that I recorded myself playing Thunderkiss, I realize how crap my rhythm is. But the guitar sounds great (mesa boogie head and cab models). Better get to practicing...
