This works for me, Randy:
\override Glissando #'style = #'zigzag
\once \override Glissando #'(bound-details left Y) = #+3
| r4 r8 ees'~ ees4 \glissando ges,8 ess
It’s an extract from Clifford Brown’s “Sandu”, and I think I got the method
from this list some years ago, and involves a gliss from the 13th fret on the D
string (Eb) down to the 4th fret (Gb).
You may have to tweak the +3 to get what you want, but I expect the expert who
supplied it will be able to explain in due course.
