Sure, I see two options here:
1. If you have miced guitars, live drums, bass and vocals the chance is very good that we will ditch our own tracks and use yours, because they are complete (you know, we are still missing vocals and a real bass).
2. If not, you can always post the tracks on another thread (like this one, where CrazyClown posted his tracks for mixing).
Well, the idea is I'm going to track bass to your song in post #1 and give you the tracks to include in your mix.
I was just checking to see that the tracks have not been updated since post #1 because it's not a good idea to record bass to the drums that aren't going to be used for the final mix, the timing will be slightly off.
I've got what i want to record set, I've just got to find the tone I'm looking for in this context.
Sounds good?
