If it's still usable for you, it's not obsolete. I have a Katana 50. It has yet to be connected to a computer. I found tones I like just tweaking knobs on it. I've had my POD HD400 for something like 8 years now. Used the online community to grab shred patches when I first got it, and maybe a few times since, but I could easily tweak and adjust from what's there to get anything I want out of it. Outside of a master volume tweak here or there, I've not changed any of the patches in probably 5 years.
