Re: Line 6 alternatives
I've never actually tried Guitar Rig. That, as well as Amplitube, is on my watchlist, so to speak. The only drawback I've found so far with Revalver is that the non-peavey amps all sound pretty dull, and the interface can be a bit daunting at first. The same goes for the virtual component modding that's included, so I've stayed away from that one so far.
What Revalver does have going for it is the ACT software, which simulates other instruments (doesn't work perfectly but still a pretty cool feature), the GIG quick-load feature and the overall sound is very nice, bot for distortion and clean. I wish the stompboxes were a bit more user-friendly, but its not a dealbreaker.
What BIAS FX/AMP does have going for it is that the amp-builder/component editor is very intuitive and easy to use. But that's also about it. I can't get a decent tone out of it to save my life, the interface isn't as cisually pleasing as Revalver (and that one is no beauty by a long shot), heck, even the tuner doesn't work. I've emailed Positive Grid about it and they said they are aware of the problem, but that's about it.
I know a few of the more well known internet guitar and tech gurus such as Fricker, Fluff and Englund all endorse BIAS and given that they're much, MUCH more experienced than me with this stuff, I'm not gonna say they're all wrong, but BIAS does not work for me one bit.
For comparison, my old Line 6 Gearbox and Pod Farm sounded better out of the box and (at laast on the distorted sounds, for cleans BIAS still blows it out of the water) and then you still had a very intutive interface to work with.
