guitar tablature and fingering

[coralline algae]

Although I have used lilypond for awhile for scores, I am just learning
to use the tabulature.  The sample score I am inserting is working
for the most part but I would like to suppress the fingering on the
note staff if possible.   Also my eyes need some assist hence
the large staff size

thanks
