MXR M117 Flanger

The MXR M117 Flanger is a classic rackmount-derived flanger in pedal form, known for its wide, sweeping jet-plane whoosh and deep, resonant metallic comb-filtering. Originally introduced in the late 1970s, it defined the sound of flanging on countless rock records — from subtle, chorus-adjacent shimmer to full, disorienting through-zero sweeps. Its sturdy construction and broad range have kept it a studio and stage staple for decades.
