Hi Tony,
When I got my pre-owned Epic the cover was missing from the E tuner.  Alembic told me that the cover isn't available seperately and gave me a price for the tuner.  I don't remember what it was exactly as I just never got around to ordering one.  That's been 4 years ago this month.  The good news is the other three covers have stayed on.  Congratulations on the new Baby.
