Behringer DD400 Digital Delay
From the manufacturer,
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.
