A burst finish refers to a guitar finish where the colour gradually fades from a darker outer edge to a lighter centre. This technique highlights the natural grain of the wood while giving the instrument depth and visual character, making each guitar look slightly different.

Common on both electric and acoustic guitars, burst finishes range from classic sunburst styles to modern colour variations. They are popular because they combine a traditional look with a visually striking appearance that complements the shape and craftsmanship of the guitar.
