I am absolutely blow away with this software. On the website, it says it works for Ubuntu, but I found that it works on Redhat out of the box as well. This software is the only guitar software I've gotten to work on Redhat. Not only does it work, but it is insanely cheap and sounds good too. I just wanted to say thanks for making this software, I'll definitely pick up both the GTX and Jam. The 3D view and tab view on Jam is awesome as well.
