SSS describes a pickup configuration using three single-coil pickups, typically found on Strat-style electric guitars. This layout offers a wide range of tonal options by allowing different pickup combinations, including the classic in-between positions that blend two pickups together.

Tonally, SSS setups are known for bright, clear, and articulate sounds with plenty of high-end detail and dynamic response. They are popular in blues, funk, pop, indie, and classic rock, particularly for clean and lightly driven tones where clarity, sparkle, and expressive playing feel are important.
