Gigging 4-6 times a month. I'm ALWAYS at least 1 firmware behind. I'm currently running 8.x... it's not because I'm scared of tone changes so much as 1.) I'm lazy when it comes to updating 2.) I don't like re-programming my pedal and 9.0 introduces scenes. The tonal change is normally so slight that I don't even care. Last upgrade I didn't even tweak the patches; they just sounded better and I went with it. I've been consciously trying to do more with less, so if push comes to shove, I could probably do an entire 4 hour bar set with my crunch patch, which cleans up enough for clean strumming and has a boost in it for leads.
IMO, the axe sounds amazing right now and I have it dialed in. I'm way more interested in playing than tweaking at this point, which is something I've never said before... ever. Often times a new amp, or a slight improvement in modeling doesn't really appeal to me when I think about re-programming things. I have the next 2 weekends off, so I'm likely going to upgrade to v9 and setup scenes with the MFC... after all, I've owned the MFC for months and haven't left the house with it. Did I mention I hate programming pedals?
