I have now changed my little guitar score

from
\relative c' { \myguitarmusicnotes }
to
\relative c { \clef "treble_8" \myguitarmusicnotes }

which does exactly what I want. No \transpose needed this way.
But I still don't understand how to do this without the little 8 printed 
below the treble clef, but still giving midi output one octave down 
without having to shift the notes on the staff one octave down.
