Thanks; I'll try it. How do I turn off the little "8" symbol by the clef?
Why do you want to remove it? This is the standard way of guitar notation.
I bit the bullet and went through all 100-odd guitar music publications I've
collected over the years, from publishers around the world on every continent,
across multiple genres (although admittedly mostly classical and South
American). The set includes many volumes whose purpose is purely
didactic. And yet I was only able to find three books that use this notation.
So I suspect that "standard" isn't exactly the right word to use here. :-)
It's probably better to say that it's the "correct" way of guitar notation -- one
that is satisfying from a theoretician's standpoint, but rarely used in practice.
But if you *really* want to get rid of it, an
\override OctavateEight #'stencil = ##f
should do the job (untested).
I'm wavering at the moment, but I'd at least like to have it as an option.
I experimented a bit and found that this variant works:
\override Staff.OctavateEight #'stencil = ##f
