BOSS's iconic DD-3 Digital Delay has been a pedalboard staple since 1986, loved everywhere for its great sound and simple operation. With the DD-3T, we've updated the classic stomp with enhanced functionality while fully retaining the original's sound and control layout. It's now possible to tap in delay tempos using the onboard switch or an external one, with your choice of three beat subdivisions. And the direct output jack has been moved next to the main output, providing easier connectivity for wet/dry setups.

- Updated version of the industry-standard DD-3, with enhanced functionality for modern players
- Ultra-easy operation for fast sound creation
- Delay time of 12.5 to 800 ms, divided into three ranges for quick setup
- Tap in tempos with the onboard pedal switch or an external footswitch
- Short Loop setting for creating phrase loops (same as the Hold function on the original DD-3)
- Direct output for sending dry and wet sounds to separate amps
- Main and direct output jacks now positioned on one side of the pedal

A Classic Through and Through
In continuous production for over three decades, the DD-3 has been the go-to delay stomp for countless players. Based on the DD-2-the world's first digital delay pedal from 1983-the DD-3 is revered for its warm, round delay tone and simple controls that let you dial in sounds fast. The DD-3T's sound circuitry and controls are identical to the DD-3, delivering every drop of that classic vibe you know and love.

Direct Out for Wet/Dry Setups
The DD-3T features a direct output jack like the DD-3, but it's been moved next to the main output jack to make connections easier. Plugging a cable into the direct out converts the main out to delay only, allowing you to send wet and dry signals to different amps for wide, immersive sounds. And if your amp or switcher has a parallel effects loop, just connect a dummy plug to the direct out to mute the dry sound for effect-only blending.

Tap Tempo On Board
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).

Hold That Loop
The original DD-3 (and DD-2 before) included a forward-thinking Hold function, which allowed you to capture a sound up to 800 ms long, play it continuously, and jam over the top. Many years later, BOSS further developed this creative concept with the successful Loop Station products, which helped spawn the new musical style of live looping. The DD-3T includes the same Hold function as the DD-3, but it's been renamed "Short Loop" to reflect today's common usage.
