Delay Time With Looping

Once it comes to the delay time, DD8 has a 10-second maximum delay time which is superior to the 6.4-second maximum delay time of DD7. That means the DD8 is able to provide more room for ambient sounds in most of the cases. Both  DD7 and DD8 have the same built-in looper function that offers up to 40 seconds of recording time. Needless to say, the Boss models prove to be powerful tools for live performances and creative experimentation.

Delay Modes

The DD7 has established a strong reputation among musicians for its versatility and reliability. It provides a versatile range of delay types, including analog, tape, modulate, reverse, dynamic, and hold. In use, rach mode provides unique sonic characteristics, from warm and vintage-inspired tones to swirling modulation and reversed textures. The DD-7’s delay options also allow guitarists to explore a wide variety of sounds and add depth and creativity to their playing.

In the case of DD-8, it takes the foundation set by the DD-7 and introduces several notable improvements and additional features. Besides features found on DD7, the DD-8 introduces warm, shimmer, and pattern modes as well which guarantee more tonal possibilities. The warm mode emulates the character of vintage analog delays and the shimmer mode adds a touch of ethereal to the sound. Finally, DD-8 incorporates the recently developed “GLT” delay mode that produces glitchy machine-gun-like effects when people press the pedal switch

Stereo Connectivity

While the DD7 offered mono connectivity, the DD-8 allows stereo input and output. Because of that, the DD-8 enables guitarists to utilize stereo setups, amplifying the spatial imaging of the delay effects. The enhancement adds depth and width to the sound, immersing listeners in a more expansive sonic experience.

Tap Tempo 

Both DD-7 and DD-8 feature tap tempo functionality as well as capabilities of using an external footswitch and onboard tap tempo. The Boss models offer the flexibility of using an external tap tempo footswitch, quite convenient as you can place the tap tempo switch within easy reach for on-the-fly adjustments. It enables precise and immediate control over the delay time, making it ideal for live performances in which timing accuracy is crucial. Meanwhile, an onboard tap tempo switch is also available, which eliminaté the need for an extra pedal. 

The tap tempo switch is easily accessible, allowing you to tap in the desired tempo quickly and efficiently. This built-in feature eliminates the need for an additional footswitch and simplifies the setup, making it more compact and streamlined.


To sum it up, Boss DD-8 builds upon the foundation of the DD-7 and introduces several notable improvements. These include an expanded range of delay modes, the innovative pattern mode, stereo connectivity, an upgraded user interface, and an extended maximum delay time. These enhancements make the DD-8 an enticing choice for guitarists seeking more versatility, creativity, and control over their delay effects. if your DD7 is on its last legs, don’t hesitate to upgrade to DD8.
