The DD-7 offers up to 6.4 seconds of delay time — a marked increase from its predecessor, the DD-6, and it offers up to 40 seconds of sound on sound recording in Hold mode. Its unique Modulation Mode offers unique chorus-type sounds, and its Analog Delay mode models the warm classic sound of the BOSS DM-2. Users can also control tap tempo, delay time, feedback, and effect level via an optional external footswitch or Expression pedal.
The DD-7’s stereo output enables the creation of amazing effects, such as spatial audio sweeps via true stereo panning. The stereo outputs can also be used to create separate dry and wet signal paths — convenient for recording and live performance control. Finally, the legendary BOSS road-tough quality and reliability come standard in the DD-7.
