I think I used Amplitube, once, a long time ago in a music room far, far away. If I'm tracking guitar or bass, I tend to use Guitar Rig. For DAW, I started with something I no longer remember the name of, then, when I switched to PCs, used Pro Audio 9 up through Sonar something or other. Think I got out around Sonar x2 or x3? Switched to Ableton Live when Gibbons bought Cakewalk. Couple version upgrades after that, I switched to Cubase Pro, primarily, but keep Live around and updated. I tend to move between them, depending on what I'm trying to accomplish.
