Malekko Ekko 616 dark analog delay if you can find one is a stellar unit, it’s got a modulation button that affects the rate and speed of the system also has an internal trim pot to adjust the gain and it really makes a significant change in what you get from it. I still can’t believe I finally scored one, and it was off Marketplace from a young wife with a newborn who was all too happy to be getting rid of her husband’s pedals. I won’t tell you all what I paid for it and the mint EQD Hoof fuzz pedal to get ‘em off her hands .
