No worries.
You guys can take your time. We couldn't go anywhere with this until I put the guide track together, so for that fast trumped pretty. I spent about two hours learning both parts. I used the first complete take on the bass, even though I had a couple of buzzes in there. The rhythm guitar was technically the fourth or fifth take, because I'm an idiot and deleted the first ones. I mixed the whole thing in about fifteen minutes, and the bulk of that was spent splicing the two rhythm guitar takes together after I completely butchered the key change first time 'round.
Point is, I expect what you guys to put up to be a lot prettier than the guide. That's why it's a guide and not the final take.
For that matter, when I do the lead I plan on spending a lot more time getting everything just right.
So yeah, take your time. Monday will be fine. I'm not expecting to have a finished product for this until mid to late January. Do what you gotta do.
