NUX NDD-6 Duotime Dual Delay Engine Pedal

Duotime is a real stereo delay pedal with independent time / sub-division & repeat knobs. In the 80’s, all of the professional musicians used rack-mount effects to run stereo delay. It was the golden era of legendary engineering like Lexicon Delta, TC 2290, Eventide H3000, and more. When we talked to “working musicians” we found that they were looking for a great stereo delay with a compact size and ultra-simple controls. So we discussed the absolutely essential requirements and developed the duotime Dual Delay Engine. It’s ultra-musical, and easy to operate. So, let’s dive-in and experience the most versatile delay pedal ever:

Duotime offers analog delay, tape echo, digital delay, modulation delay, and verb delay.

Analog Delay (40ms~402ms) is based on the bucket-brigade device (BBD), discrete-time analog delay. The PARAMETER tweaks your modulation depth. When LEVEL and REPEAT are at maximum, turn down the TIME KNOB to zero, and experience the natural infinite feedback of the old school BBD delay.

Tape Echo (55ms~552ms) is based on RE-201 Tape Echo algorithm with NUX Core Image Technology. Use the PARAMETER to tweak the Saturation, and feel the distorted sound decay. Just like the real tape echo machine, when you adjust LEVEL and REPEAT to maximum, try adjusting the time knob down to zero, and you have infinite feedback and pitch shift flange.

Digi Delay (80ms~1000ms) is based on the modern digital delay algorithm with magic compression and filter. After reviewing decades of delay algorithm evolution, we noticed musicians were not satisfied with the mathematical digital delay sound. So we added a bit of non-digital flavor—inspired by Strymon® and Neunaber® making the sound much more musical.

PARAMETER controls the hardness of the repeat signals, so you can feel the unique compressed filter.

MOD Delay (20ms~1499ms) is based on the Ibanez DML algorithm; a weird and wonderful modulation delay. It was released in the 80’s with experimental nature. We selected the most wonderful aspects highlighting the musical time sync modulation rate offering a simple, seamless romantic tone.

VERB Delay (80ms~1000ms) is the way to make your delay sound 3 dimensional. Similar to our Atlantic Delay & Reverb, we added Shimmer into the Plate reverb algorithm. It became the iconic sound of our NUX reverb. Inspired by Kit Tang, the famous Hong Kong studio guitarist, Jamtrackcentral® artist, a master of different reverb parallels with different frequency bands to add to his effect yielding an authentic 3 dimensional sound. So we combined parallel digital delay, plate reverb, and various filter shimmers to offer you an unmatched sacred atmosphere to explore.

PARAMETER controls the Plate reverb and shimmer mix.

CONTROL PANEL

LEVEL Knob：Controls the delay mix level.When using ENTER LOOP mode, the LEVEL knob will become your LOOP LEVEL to control Phrase Loop volume.

Delay Type Selector: This is a 5-way rotary switch. You can choose the delay type as ANALOG, TAPE, DIGI, MOD., and VERB.

PARAMETER: For Analog Delay, PARAMETER controls Modulation Depth. Increase to get wider modulated sound.

For Tape Echo, PARAMETER controls signal saturation. Increase to get more saturated and distorted sound.

For Digi Delay, PARAMETER controls signal hardness. Increase to get a more compressed and brighter sound.

For Mod Delay, PARAMETER controls Modulation Depth. Increase to get a wider modulated sound.

For Verb Delay, PARAMETER controls Reverb and Shimmer mix level. Increase to get more depth and a 3 dimensional feeling.

TIME 1: Controls delay1’s delay time. When in Tap Tempo, it becomes a sub-division according to current parameter.

REPEAT 1: Controls delay1’s number of repeats.

TIME 2: Controls delay2’s delay time. When in Tap Tempo, it becomes a sub-division according to current parameter.

REPEAT 2：Controls delay2’s number of repeats.

TAP Footswitch: Tap this foot switch to adjust the speed and delay sub-division. You can set the target sub-division by TIME 1 and TIME 2 knobs, then TAP this foot switch to adjust the speed, the DELAY 1 and DELAY 2 will change the delay time according to the current sub-division note signature. Hold this foot switch for 2 seconds, to switch current delay time between MS or BPM.

OLED Display: Shows current Delay type, and delay time in MS/BPM.

LOOP Mode: Press ON and TAP foot switch simultaneously, to enter / quit PHRASE LOOP mode. In LOOP mode, press ON foot switch to activate REC/PLAY/DUB and hold to UNDO/REDO as a normal looper pedal. OLED display shows your phrase loop status. LEVEL knob becomes LOOP LEVEL to adjust phrase loop volume. (Pedal will remember the current delay mix level when you enter LOOP mode.) All other knobs work in normal mode independently.

INPUT/OUTPUT

IN 1 (MONO): If you only connect with IN 1, then IN 1 signal will run DELAY 1 related to TIME 1 and REPEAT 1 knobs for OUT 1. Pedal will copy IN 1 signal to run DELAY 2 related to TIME 2 and REPEAT 2 knobs for OUT 2.

If you connect using IN 1 and IN 2, then IN 1 and IN 2 will run DELAY 1 for OUT 1 and DELAY 2 for OUT 2 separately.

IN 2: If you only connect with IN 2, then IN 2 signal will run DELAY 2 related to TIME 2 and REPEAT 2 knobs for OUT 2. Pedal will copy IN 2 signal to run DELAY 1 related to TIME 1 and REPEAT 1 knobs for OUT 1.

If you connect with IN 1 and IN 2, then IN 1 and IN 2 will run DELAY 1 for OUT 1 and DELAY 2 for OUT 2 separately.

OUT 1 (MONO)：OUT 1 signal is related to DELAY 1.

OUT 2: OUT 2 signal is related to DELAY 2.

USB Port: You can update firmware using the USB port. Please check our product page “Support” and follow instructions.

DC Jack: Use ONLY: 9V Negative Tip power with 300ma.
