BOSS' MOST POWERFUL DELAY PEDAL.

The BOSS DD-20 Digital Delay offers more User memory and long delay time up to 23 seconds. Delay time can be quickly set using the push-button knob or via tap tempo. And with a choice of 11 modes—including new “Smooth” and “Twist” delays and sound-on-sound recording—this Twin Pedal raises the bar for delay effects.

23 Seconds of Pro-Quality Delay

With up to 23 seconds of delay, the DD-20 easily outshines the competition and can even double as a sound-on-sound pedal. Delay time can be adjusted via tap tempo or using a knob, which also features a push function to set the delay range more quickly. Eleven delay modes are provided covering everything from analog and tape delay to reverse delay and more. A new Memory function makes it possible to change delay modes

New “Smooth” and “Twist” Modes

The DD-20 also introduces two all-new delay effects that are sure to blow some minds. Twist creates wild delay effects similar to “over the top” manipulation of an analog tape echo, while Smooth creates ultra-smooth delay effects. This is a pedal no guitarist should be without!
