I recently purchased shreddage 2 and am more than happy with it. I only have one issue, which is probably my error. I decided I would bounce down shreddage with guitar rig 5 providing distortion to four separate wav files. When I imported them into my mixing session they had extremely bad phasing issues as I panned them. I haven't tried anything else out yet. A second question, when double tracking should I use same amp settings, different or completely different amp? What about left from right guitars? Sorry for newbie questions, have never been a guitarist.
