A key addition the DD-3T brings is tap tempo, an essential feature for creating the rhythmic delay effects at the heart of many guitar styles. In delay mode, hold the pedal switch for two seconds to toggle between bypass and tap operation. And for on-demand tap control, simply connect an external footswitch. When the DD-3T receives tap input, up to 800 ms of delay time is available, and the Mode knob sets the tap subdivision (quarter-note triplet, dotted-eighth note, or quarter note).
