Bass, guitar, & ukulele notes

Every string-and-fret position on these three instruments plays a note, and the same notes turn up again and again across each neck. Each note also falls in one of six octaves. Where do the bass, guitar, and ukulele overlap? Each column is a string and each row a fret. Colors mark notes: solid for naturals, blended for sharps. The ring above each instrument shows every note it can play, octave 1 on the outside.
