pretty good, nice execution, and im sure this is not targeted at people like me. but i figure i would add, just for those that are curious: there is more to tuning than just this. how hard you play the strings, where on the neck you play, the relative gauges, what the weathers going to do, the sound you like- all things that make it more complicated. there is also what your bandmates are doing. there are also mechanical factors that make for difficulty in getting the string to make the pitch you want, as other posters noted. i say all this to celebrate the wonderful endless complexity that "simple" things have when they exist in the real, corporeal world. its something i think can be forgotten by people who hang out on a computer mostly.
