Ekko is a delay effect with adjustable parameters. Dial up the Feedback to hear the delay echoing beyond the original sound. Increasing the Dampen dial decreases the sound of the delay effect compared to the original device sound. The Wet/Dry dial determines the amount of original sound you hear through the effect; the closer to Dry, the more intense the raw sound and the less audible the delay. Syncing the delay rate causes the delay to sound in time with the session tempo. Adjust the rate to make the delayed sound faster or slower.
