The Electro Harmonix Andy Summers Walking or The Moon Flanger pays homage to Andy's distinctive sound, which he coined with Sting and Stewart Copeland in the early years of The Police. The analogue flanger effect offers a simple but effective control surface: the Rate control sets the modulation speed of the effect, while Range defines the width of the sweep. The Color knob also plays an important role here, allowing you to control the flanger effect from subtle chorus-like sounds to powerful flanger wooshes. Last but not least, there is an additional Filter Matrix Switch. This decouples the LFO from the flanger circuit and fixes the filter in one position, allowing you to elicit further interesting timbres from Andy Summers Walking or The Moon Flanger .
