Hi Valentine,

thanks for your suggestions.
I've come up with this new code (see file attached).

It's my first tweaking, so it might be "naive"..
Anyway, it works :-)

Actually, it can be used in any fretted instrument, not only guitar..
Anyway, choose what you think is better..

\version "2.12.1"
% since version 2.13.4 you won't need to include tablature.ly
\include "tablature.ly"

%% Hide fret number: useful to draw slide into/from a casual point of
%% the fretboard.
hideFretNumber = { \once \override TabNoteHead #'transparent = ##t 
                 \once \override NoteHead #'transparent = ##t 
                 \once \override Stem #'transparent = ##t
}

music= \relative c' {
      \grace { \hideFretNumber d8\2 \glissando s2 } g2\2
      \grace { \hideFretNumber g8\2 \glissando s2 } d2 |
