I've now been at this for over a week, and so far, I'm liking the progress. I've already got ideas for a few more songs every now and then while at work, but I haven't had a chance to write or play most of them (wrote down the lyric-ideas I've come up with during a break, though. You never know when they'll come in handy).

I've got a to work a bit more on the melody and messed with some settings, and found that the Lead Guitar and Rhythm Guitar parts each sound better on one guitar than on the other. The Lead Guitar sounds better on my Strat with Humbuckers, since it sounds a bit more crispy, while Rhythm is better off on my SG, for some reasons. I don't know why, it just sounds a bit deeper or darker.

As for how much exactly I have nailed down, I have the Rhythm guitar parts for Verse 1 (still need a better intro), Chorus 1, Verse 2, Chorus 2 and the Bridge just before the kickass solo comes in. Still no Lead-lines yet...
