I, and I'm sure many others here, feel your pain. I had been working on one song for quite a few days and I don't know what happened in the process, I'm guessing the knobs on my amp were turned around or something, but no matter what I did I just couldn't get it to give off the same tone I originally had. And it sounded really abstract and just didn't work. Like a band recorded the first half and then let some other band finish it. So I had to scrap the whole thing and start over just so I would be satisfied.
