Hi,

not sure I understand.
Like below?

\version "2.19.82"

\layout {
  \context {
    \Score
    tablatureFormat =
      #(lambda (context string-number fret-number)
        (let* ((my-signs
                '(0 1 2 3 "#" 4 5 6 7 8 9 "b" 10 11 12 13 "1#" 14 15 16 17 18))
               (ls-length (length my-signs))
               (my-sign
                 (if (> fret-number (1- ls-length))
                     fret-number
                     (list-ref my-signs fret-number))))
         (if (integer? fret-number)
             (make-vcenter-markup
               (format #f "~a" my-sign ))
             (fret-number-tablature-format context string-number fret-number))))
  }
}

\new TabVoice
  \relative e' {
    e f fis g gis a ais b c cis d dis e f fis g gis a ais b c cis
  }


Cheers,
