Celebrating the classic, shimmering flanger sounds of Andy Summers, the EHX Walking on the Moon is a tribute to the tones Andy employed while carving his niche in the early days of playing with the Police. Liquid flange effects that hint toward chorus with extra depth and nuance make Andy’s sound one of the most coveted in all of the guitar universe. The Andy Summers Walking on the Moon is an analog flanger with a simple but powerful control set of Rate, Range, and Color. Rate sets the speed of modulation which ranges from slow, smooth filter sweeps to jittering vibrato. Range controls how narrow or wide the effect sweeps into the bass frequency range. The Color control effects the intensity of the flanger effect from subtle chorusing effects to classic jet woosh sounds.
