Hey, I'm looking to make an effect on my pedal and was just wondering for starters what this might be identified as. It's gives a shimmering in and out sound, maybe just a fast delay? An example would be in the intro of butch walker's cover of "born to run", as well as probably the original, but check out butch's right here with the link below cos I'm really looking to get an effect like this. Thanks.
