Well this is the 6th flash update so far isn't it? I don't recall how many of them I had already installed but for sure this was the first one that drastically altered the tone- at least in my experience anyway.
Maybe you misunderstand my comment about turning up to the next gig- obviously I played the guitar when I updated it, it was in my hand at the time, hooked up through my HD500, but not at stage volume. I can understand if you believed I flashed the memory without checking it had worked, but that is not what I said.
Because of the usb issue I didn't have time to find the interface so I could gen up on the new workbench and restore my custom settings ( for ease of use I have the neck and bridge LP, Strat 4th position, electric 12 string and Peter Green's LP in a single bank ) but my Pod is programmed to switch guitars according to the patch I select. (the custom bank is just to give easy access to alternatives regardless of the patch I'm using eg Pink Floyd stuff where I've programmed a strat but sometimes switch to a LP during solos for that bit of extra sustain)
Make no mistake, forwards is the only direction I am interested in...otherwise I may as well go back to my Ibanez which is lighter and much easier to play but doesn't have the versatility obviously...so 2.0 is staying- at least until 2.x comes out...lol
