The NUX NML-3DLS Dual Loop Stereo is a stereo looper pedal with a built-in drum machine. It carries 42 rhythm presets with 672 rhythm variations1, and six knobs handle the Volume/Gain of Track 1, Track 2, Drum 1, Drum 2, Mic Level and Master volume1.
Two loops and two drum patterns
The core idea is independence: the pedal carries dual loop tracks and two distinct drum patterns, so a player can record one loop, layer a second, and give each its own rhythm part2. The drum section draws on 42 rhythm presets with 672 rhythm variations2. Under the hood, NUX uses 32-bit AD/DA conversion and 32-bit floating-point processing2.
Recording time is generous by looper standards: 26 hours of stereo recording in total, with up to 90 minutes of stereo recording on a single track2. For comparison, the NUX Loop Core is the company's earlier single-loop design, and the Donner Circle Looper and MOOER GL200 are other compact loopers with drum accompaniment.
Controls and connections
The top panel is built around six knobs that set the Volume/Gain for Track 1, Track 2, Drum 1, Drum 2, Mic Level and Master volume2.
| Knob | Controls |
|---|---|
| Track 1 | Volume/Gain of the first loop track |
| Track 2 | Volume/Gain of the second loop track |
| Drum 1 | Volume/Gain of the first drum pattern |
| Drum 2 | Volume/Gain of the second drum pattern |
| Mic Level | Volume/Gain of the microphone input |
| Master | Overall output volume |
The connection panel covers most stage and practice needs:
- Stereo inputs and stereo outputs2
- XLR jack with 48 V phantom power, for a microphone2
- 3.5 mm AUX input2
- 3.5 mm headphone output2
- 3.5 mm MIDI IN/OUT2
- EXP expansion, for an expression pedal or external control2
The XLR input carries 48 V phantom power, so a condenser microphone can be plugged straight in. The MIDI and EXP connections use 3.5 mm jacks rather than full-size DIN or quarter-inch sockets, so adapters may be needed with older MIDI gear.
What reviewers said
Pedal of the Day's review was warm across the board. The reviewer described the NML-3DLS as "this remarkable dual-track loop pedal" that "will ignite your imagination," and closed by calling it "an exceptional companion for guitarists, singer-songwriters, and all musicians" eager to explore looping2.

Questions
Does the NUX NML-3DLS take a microphone?
Yes. The NML-3DLS has an XLR jack with 48 V phantom power, so a condenser microphone can be connected directly. A dedicated Mic Level knob on the top panel sets the microphone's volume or gain alongside the two loop tracks, the two drum channels and the master output, which is what makes the pedal usable for singer-songwriters as well as guitarists.
Does the NUX Dual Loop Stereo have a headphone output?
Yes. Alongside its stereo outputs, the NML-3DLS carries a 3.5 mm headphone output, plus a 3.5 mm AUX input for playing along with an external source. That makes it possible to practice and loop silently through headphones.
How much recording time does the NUX NML-3DLS have?
The NML-3DLS offers 26 hours of stereo recording time in total across its two loop tracks. A single track can hold up to 90 minutes of stereo recording, which is far beyond the length of a typical performance or song arrangement.
Does the NUX NML-3DLS support MIDI?
Yes. The pedal has 3.5 mm MIDI IN/OUT connections, so it can be synced or controlled with other MIDI-equipped gear using 3.5 mm TRS MIDI cables or an adapter. It also has an EXP expansion connection for an expression pedal or external switch.
Can I connect an expression pedal to the NUX NML-3DLS?
Yes. The NML-3DLS includes an EXP expansion connection, which is designed for an expression pedal or similar external control. It sits alongside the 3.5 mm MIDI IN/OUT jacks on the pedal's connection panel.
