Introducing the DD-8, the most wide-ranging and feature-rich BOSS compact series delay ever. This loaded pedal delivers more of everything—more great sounds, more delay time, more control options, and more connectivity. And it does it all in a standard BOSS pedal that slides easily into any mono or stereo setup. Eleven modes provide delay colors from basic to exotic, plus a looper with unlimited overdub capability and external control support. For maximum versatility in a minimum amount of space, there’s no better delay stomp than the DD-8.
