Signature models are instruments or pieces of equipment developed in collaboration with a specific artist, built around their personal preferences, playing style, and sound. They are usually based on a proven design but include customised specifications such as pickups, electronics, hardware, finishes, or neck profiles chosen by the artist.

These models give players access to tones and features shaped by a particular musician while remaining practical for everyday use. Some signature instruments involve subtle refinements, while others are highly distinctive, appealing both to fans of the artist and to players who value the specific characteristics built into the design.
