Bouzouki Chord Chart and Fretboard Poster GDAD Tuning on ebay
This is what I found on ebay today. A poster containing the fretboard of a bouzouki GDAD tuning and some chords for $6.95 or 5,26€. Maybe this could be helpful to someone? In my opinion the price is much too high. Of course it is a good idea to put the info on a poster, so you can have a look at it if in doubt, especially for the fretboard. I did this for myself years ago and it still hangs on my wall. But the few chords are of no great help. In my opinion no chordchart is of any help for the bouzouki, because you seldom play full chords on the bouzouki. You need to have several different shapes for each chord and try everytime which one fits best into the structure of the other chords you play. But decide for yourself.
Look at it as long as the link is valid:
