Clippage - it seems like it's wherever you overlapped your different guitar parts. So if you sent me each separate clip I could work around that, plus I could do panning of each separate track. The buzzing at the very end is an EQ problem (way too much bass), but I think I can fix that.
P.S. What do you want to do with the rest of this thing? If Ed's not going to sing we'll have a lot of open space.
