The Mooer Micro Drummer II is a mini drum machine pedal from Mooer that plays recorded drum grooves behind your playing. MOOER describes it as "a new drum machine that delivers realistic drum sounds and a wide range of features for musicians of all levels," and it holds 48 grooves spread across six music types: Pop, Funk, Metal, Rock, Blues and Jazz1. It arrived in June 2023 alongside the Micro Looper II, and Guitar World's reviewer noted that, on paper, TC Electronic's Ditto+ serves both looper and drum machine purposes in one unit, giving it added versatility as an all-in-one option2.
What it does
The Micro Drummer II is built around 48 grooves, and the six music types they are grouped into cover Pop, Funk, Metal, Rock, Blues and Jazz, according to gearnews.com's launch report3. Each music type carries eight rhythm types, so within a style you have several different feels to choose from rather than a single beat1.
| Music type | Rhythm types |
|---|---|
| Pop | 8 |
| Funk | 8 |
| Metal | 8 |
| Rock | 8 |
| Blues | 8 |
| Jazz | 8 |
MOOER specifies a 44.1kHz / 24-bit sample rate and depth for the drum sounds1. Tempo runs from 40bpm to 240bpm1, which reaches from a slow blues shuffle to speeds well beyond most rock and metal material. On the original Micro Drummer, the SPEED control adjusts the speed of the grooves and the footswitch can be tapped in time to set the tempo, and the II follows the same mini-pedal approach4.
Because the input and output are both mono 1/4-inch jacks, the pedal sits in a single signal path: guitar in, drum mix and guitar out together through the one output1. That makes it a practice and jam tool as much as a performance pedal, since the drums play alongside whatever you feed it.

Power and practical details
The Micro Drummer II needs a 9V DC, center-negative supply at 120mA1. There is no battery operation in the specification, so it is a pedalboard-power pedal rather than something to run off a battery clip. The original Micro Drummer had the same adapter requirement, with a 95mA current draw, and MOOER recommended its own Micro Power supply for it4.
At 120mA1, the Micro Drummer II draws more current than many low-drain mini pedals, so check what your power supply outputs deliver before adding it to a daisy chain.
The pedal measures 93.5mm deep, 42mm wide and 52mm high, and weighs 157g, so it takes up about as much board space as a standard mini enclosure1. The box includes the owner's manual1.
Price and how it compares
Guitar World's June 2023 news report put the Micro Drummer II at $103 at launch2. Guitar World has also listed it at $79/£795, and gearnews.com's report of the launch gave a Thomann price of $79.00 / £72.00 / 84.00€3. The figures differ between outlets and dates, so the going price has moved around since release.

| $79/£79 | Guitar World5 |
| $79.00 / £72.00 / 84.00€ (Thomann) | gearnews.com, June 20233 |
Against the alternatives, Guitar World's news editor noted that TC Electronic's Ditto+ serves both looper and drum purposes in one unit: "On paper, the Ditto+ serves both purposes in one unit, and as such that added versatility still serves a potent hook for" players weighing the two2. Within Mooer's own range, the Groove Loop combines a looper with drum grooves, and the original Micro Drummer offered 121 drumbeats across a wide variety of musical styles where the II offers 48 grooves in six types41. Other drum machine pedals in the same space include the Singular Sound BeatBuddy and the DigiTech SDRUM.

Questions
Does the Mooer Micro Drummer II take a battery?
No battery is part of the Micro Drummer II's power setup. MOOER's specification calls for a 9V DC, center-negative power supply at 120mA, the same adapter arrangement as the original Micro Drummer. Plan to run it from a pedalboard power supply output or a dedicated 9V adapter rather than expecting battery power.
What power supply does the Micro Drummer II need?
MOOER specifies a 9V DC supply, center negative, drawing 120mA. That current draw is modest by pedal standards, but it is above what some very low-current daisy-chain outputs deliver comfortably, so a dedicated supply output or a Mooer Micro Power style adapter is the straightforward choice.
What is the tempo range of the Micro Drummer II?
The Micro Drummer II runs from 40bpm to 240bpm, according to MOOER's product page. That covers slow ballad tempos through to fast punk and metal feels, and the speed can be set by tapping the tempo button in time with the feel you want, as on the original Micro Drummer.
How much does the Mooer Micro Drummer II cost?
At its June 2023 launch, Guitar World reported the Micro Drummer II available for $103. Guitar World has also listed it at $79/£79, and gearnews.com's June 2023 report gave a Thomann price of $79.00 / £72.00 / 84.00€. Prices have varied depending on the retailer and date.
Is the Micro Drummer II input and output mono or stereo?
Both jacks are mono. MOOER specifies a 1/4-inch mono audio input jack with a 470k ohm impedance and a 1/4-inch mono audio output jack with a 100 ohm impedance, so a single mono feed to your amp or the next pedal is what it is built around.
