As for updates, I own all these modelers and have them in use at the studio. If there is a big significant change firmware that completely changes the sound of these presets we'll most likely do a free update. I have to say that one of the reasons I have been hesitant in doing this during all these years is the possibility of new firmware making the presets obsolete but I've been very happy with not having to tweak presets after firmware updates for about two years now.
Have you tried these presets with FW3 yet, and if so, what's your opinion on how the sound changed?
