The Behringer Digital Delay DD400 effects pedal has an obsession with the past—the last 1.3 seconds of it, to be exact. The Behringer Digital Delay will sing the fading, ghostly praises of every note you squeeze from your guitar. With seven modes of delay to choose from, there is a vast palette of echoes to explore with the DD400. Take advantage of its full 1.3-second memory or scale it back for a more abrupt echo. Just twist the dedicated Mode, Time, Feedback and Level controls to create the delay of your dreams. There is also a HOLD mode that allows you to loop a brief riff, then play over it. The blue LED tells you when it’s on, and the first-class on/off switch maintains incredible signal integrity in bypass mode. You can power the DD400 with a 9 V battery or a DC power adapter.
