I’ve used this in Logic Pro 8 and 9 without a problem.

I have a Mac Pro 2.66 Quad Core with 8 GB of ram and a White Macbook with Intel Core 2 Duo Cpu with 4 GB of Ram.
The installation is really easy and the the manual is clear and precise.


Back in the day, Guitar Rig was the first Amp simulator that I’ve tried. Since its first release, the guys at Native Instruments worked really hard in these years to implement features and improve the sound quality. I’ve used it in different genres, recorded a few demos with and it was a good software (even on other sources like drums and voice to create some cool effects).
The best thing about the program is that you can use it as a sound design tool, with complex fx chains.

The sounds are average, you have to use some external plugins to spice things up and resolve some fizzy problems.

My overall opinion is that for most of the time the simulations will sound weak and thin, there are other guitar and bass sims out there, even for free like the ones from LePou, that are esponentially better than this. Hope they will improve things in the future because Native Instruments is a great company.
