MXR 117 Flanger

The MXR 117 Flanger, first released in 1978, is a classic modulation pedal known for its rich, dynamic flanging effects. Designed with a high-headroom analog circuit powered by an AC cord (later updated to a modern 18V DC adapter), the pedal offers controls for Manual, Width, Speed, and Regen, enabling a wide range of sounds from subtle modulation to jet-plane-like sweeps. The MXR 117 Flanger became a staple in the late 1970s and 1980s, widely used across rock, funk, and experimental music. Its enduring popularity led to reissues such as the M117R and signature models like the EVH117, which features Eddie Van Halen's iconic settings.
