BOSS DD-3T Digital Delay Pedal with Tap Tempo

BOSS DD-3T Digital Delay Pedal

The BOSS DD-3T Digital Delay Pedal delivers 12.5 to 800 ms of digital delay in a compact stompbox, with three delay ranges, tap tempo, Short Loop, and dedicated wet/dry routing. It preserves the DD-3 sound circuitry and familiar control layout while adding tempo control for more flexible live and studio use.

Players can create everything from tight slapback-style repeats to longer rhythmic echoes using dedicated E.LEVEL, FEEDBACK, TIME, and MODE controls. Onboard tap tempo makes synchronization straightforward, while an optional external footswitch provides dedicated tempo control. The DD-3T also works well for guitar pedalboards needing wet/dry amplifier routing or a compact digital delay with tap tempo.

The DIRECT OUT jack separates the dry signal from the delayed output for dual-amplifier and parallel-effects configurations. Buffered bypass supports longer pedalboard signal chains, while a 1 M ohm input impedance suits instrument-level sources. Power comes from an included 9 V alkaline battery or an optional BOSS PSA-series AC adapter.

Key Features

• 12.5 to 800 ms Delay Range: Covers short echoes, rhythmic repeats, and longer ambient delay effects across three selectable ranges.
• Onboard Tap Tempo: Sets delay timing directly from the pedal switch without requiring additional control hardware.
• External Tempo Control: A dedicated TEMPO jack supports optional FS-5U, FS-6, and FS-7 footswitches.
• Three Beat Subdivisions: Tap-tempo operation supports quarter-note triplet, dotted-eighth-note, and quarter-note timing.
• Short Loop Mode: Captures and continuously repeats a phrase up to 800 ms, retaining the original DD-3 Hold concept.
• Wet/Dry Routing: Separate OUTPUT and DIRECT OUT connections allow delayed and unaffected signals to feed different amplifiers.
• Buffered Bypass: Maintains an active buffered signal path when the delay effect is disengaged.
• Compact BOSS Format: Fits standard pedalboards while providing dedicated controls for effect level, feedback, delay time, and mode.
