It installed on my computer with no problems. I didn't have any issues with compatibility, because Sonar accepts VST as well as DX versions of plug-ins. Guitar Rig is very easy to set up, the installer doesn't take very long and you are walked through it every step of the way. The only thing that could be confusing is the serial key entering, which is a little different from most companies, but it's not really hard to handle. The manual is pretty detailed, so I think it's all good there.

SUITABILITY/PERFORMANCE

I have a custom built audio computer from Sweetwater which is about 6 months old, so it is a pretty top of the line system. Guitar Rig works very nicely on it. It doesn't use too processor power so you could definitely run a bunch of these if you wanted something like a wall of guitars effect, or just a lot of lead guitars playing at once. It seems to be very stable, it hasn't caused any problems that I remember.

OVERALL OPINION

I have had Guitar Rig 2 for years. I haven't gotten the upgrade to version 3 because honestly I think GR2 sounds great and I am perfectly satisfied with it, so I don't see the point in spending more money. You have a huge choice of different kinds of amps and amp heads, all kinds of different rack effects and stomp boxes, you can tune your guitar with it, and the samples of presets that they give you are killer. You can really pretty much create and guitar tone you could dream up with Guitar Rig, and then you'll find some in the presets that will blow your mind. It's true that it doesn't sound quite as good as a real amp, but it comes very close. In a dense mix, it would be very hard to tell the difference. I really like this plug-in and I think it's a great value. I would get it again.
