I've read up on it and I like it. Just you have to suscribe to guitarport.com to get the full effect. It automatically gives your ax the tone of any song they have in thier archive which to is good because you feel better about playing when you sound exactly like the greats. They have tab and back up music that you can play with. I'd say its worth buying if you want to use the sound Hendrix uses on Purple Haze
