Sound spretty good man.
I have a mate who might be able to do vocals over it but probably not for a while.
I think the guitar tone sounds a little weak in a way, but it's kind of close to the original and their tone had a really weird quality to it on that album, which was great.
Maybe also lower the snare a touch in the mix.
I'll elt you know about my mate who can do vocals. It probably won't be for around a month or so as I'm going away for uni holidays soon.
