Funk guitarists playing rhythm guitar generally avoid distortion effects and amp overdrive to get a clean sound, and given the importance of a crisp, high sound, Fender Stratocasters and Telecasters were widely used for their cutting treble tone. The mids are often cut by guitarists to help the guitar sound different from the horn section, keyboards and other instruments. Given the focus on providing a rhythmic groove, and the lack of emphasis on instrumental guitar melodies and guitar solos, sustain is not sought out by funk rhythm guitarists. Funk rhythm guitarists use compressor volume-control effects to enhance the sound of muted notes, which boosts the “clucking” sound and adds "percussive excitement to funk rhythms" (an approach used by Nile Rodgers).
