Delay is the cornerstone of almost every guitarist's pedal board. The NUX ADP-10 is a delay with completely analog circuits and 3205 and 3102 BBD chips. It creates a warm dynamic effect that brings one's guitar playing to life. There is a knob for "delay time", one for repetitions "repeat" and a "blend". If you want to let loose, turn it up and let the pedal create chaos, otherwise dial a bit more gently and brighten up your guitar playing.
