You want to run two delays and a reverb pedal to give yourself that wash of sound, OR you get the Ambience pedal which blends two syncopated but individualy modulated echoes that swell into a lush reverb. All in one pedal with three easy controls. The span is the time of the two delays and their correlation between each other, and the decay controls both the feedback of the echoes as well as the amount of reverb added. Lastly you have a level knob which is very helpful to boost your signal to cut through if needed since it is becoming a wash of gooey ambience.
This pedal is in excellent used condition.
