no, I just listened to Crooked Jack - I'm at work and was planning on listening to the others after a meeting. Well it's damn good for a totally live recording. If you've got each instrument on separate channels I'd consider panning the backing vocal a bit further away from the main one if you can.

I'll feel smug about having spotted the guitar being put through the desk. Acoustic guitars always sound a tiny bit "plasticy" when they're not micd up, because essentially you're not getting what you're ears hear – sounds coming through a sound hole, fingers on the fretboard.
