Gbmaj7 on the guitar
Standard tuning (E A D G B E). Strings run low E on the left to high e on the right, frets downwards; × is a muted string, ○ an open string, and each dot shows the note it sounds, with the root in blue-green. Every shape below has Gb as its lowest note.

The E-shape and A-shape grips are movable: an E-shape chord's root is the note under your first finger on the low E string, an A-shape chord's root is the note on the A string. Slide the same grip up or down to play major seventh chords on other roots.
Gbmaj7 on the ukulele
Standard ukulele tuning is G C E A, drawn with the G string on the left and frets downwards, as ukulele chord charts show it. The G string is tuned higher than the C string (G4 above middle C, a fifth over C4), so the lowest note you hear is usually on the C or E string, not on the G string, and a shape can sound as an inversion even when its root is on the G string. All four strings are strummed, so every string plays a chord tone; the root is in blue-green.
