n order for a guitarist to be able to quickly navigate the fret, manufacturers leave special markers. The most common type are circular markers in a contrast color. It is the most simple solution for production. Some manufacturers take this markers quite seriously and make it work in favour of their brand. Sometimes fret markers become an exquisite work of art: the birds on the PRS, the isosceles trapezoids on the Gibson or shark fins on the Jackson.
The DGT (David Grissom Trem)
PRS's signature fret markers include the standard moon inlays and the optional and sought after birds, often fashioned from pearl or paua (abalone) shell. The bird inlays feature representations of the following species; peregrine falcone (3rd fret), marsh hawk (5th fret), ruby throated hummingbird (7th fret), common tern (9th fret), Coopers hawk (12th fret), kite (15th fret), sparrow (17th fret), storm petrel (19th fret), a landing hawk (21st fret) and a screech owl on a branch (24-fret models only). 20th and 25th anniversary edition production models feature updated and stylized versions of this standard inlay.
