The MOOER Ensemble Queen is a bass chorus pedal from MOOER Audio, pitched at bass players who want a chorus voice on a crowded board. MOOER describes it as "a new choice for your Pedal Board," and says that pressing the footswitch delivers "the rich and stereo Chorus sound, which makes your performance more vivid with the excellent atmosphere."1
It is built in the mini dimensions of Mooer's Micro Series, which the maker says is to "save more room of your pedal board for more pedals."1
The controls
The Ensemble Queen keeps its front panel to four knobs, each with a single job:
| Control | What it does |
|---|---|
| RATE | Chooses the rate of the effect sound1 |
| DEPTH | Controls the depth of the Chorus effect1 |
| TONE | Adjusts different tones of effect1 |
| LEVEL | Adjusts the volume of the Chorus effect1 |
That layout covers the usual chorus questions: how fast the modulation runs, how strong it is, how the effect is voiced, and how loud it sits against your dry bass signal1.
Power and hooking it up
The pedal takes a 9V DC AC adapter with a center minus plug, and MOOER recommends its own MICRO POWER supply. Current draw is listed at 110mA.1
At 110mA, the Ensemble Queen draws more current than many compact pedals. Make sure the output on your pedalboard supply is rated to deliver at least that before plugging it in.
Connections are a single 1/4" monaural input with an impedance of 470K Ohms and a single 1/4" monaural output with an impedance of 100 Ohms.1
Size and bypass
The enclosure measures 93.5mm deep by 42mm wide by 52mm high and weighs 145g, matching the Micro Series footprint MOOER uses across its compact line.1
MOOER states the pedal will "ensure to keep the original sound with the True Bypass status," meaning the effect is removed from the signal path entirely when switched off.1

Questions
Is the MOOER Ensemble Queen true bypass?
Yes. MOOER Audio states the pedal keeps the original sound with the True Bypass status, so when the effect is switched off your bass signal passes through without the chorus circuit coloring it. That matters on a bass pedalboard, where preserving low-end clarity in bypass mode is often a priority.
What power supply does the MOOER Ensemble Queen need?
The Ensemble Queen runs on a 9V DC AC adapter with a center minus plug. MOOER recommends its own MICRO POWER supply. There is no battery option mentioned, so plan for a dedicated adapter output or a pedalboard power supply with a center-negative 9V connection.
How much current does the MOOER Ensemble Queen draw?
MOOER lists the current draw at 110mA. That is higher than many simple analog pedals, so check that the output you use on your power supply can supply at least that much before adding the Ensemble Queen to a daisy-chained or shared setup.
How big is the MOOER Ensemble Queen?
The pedal measures 93.5mm deep by 42mm wide by 52mm high and weighs 145g. It follows the mini dimensions of Mooer's Micro Series, which MOOER says is intended to save room on a pedalboard for more pedals.
Does the MOOER Ensemble Queen have a Rate knob?
Yes. The RATE knob chooses the rate of the effect sound, working alongside the DEPTH knob, which controls the depth of the Chorus effect, and the TONE knob, which adjusts different tones of the effect.
