This Chinese maker has become over time an important player in the guitar gear space, with a pretty large offering of guitar effects pedals, with attractive and budget prices but with a good price-performance ratio. Mooer has also an offer which covers multi-effect processors with models such as the GE 300 and GE 200, a large set of interesting preamp pedals or pedals like the Baby Bomb, which is a 30 watts power-amp in a pedal format.

The Mooer Radar was launched in 2017 : it is an impulse response loader in a pedal format. The Mooer Radar surprised and interested a lot of guitar players as it is delivering a lot of features in a very small and compact pedal format, with a very attractive price tag. The pedal offers a small colour screen, and is controlled by a unique rotary / push button.

If you are not into using a Mac or a PC to play guitar or if you are looking for an ultra transportable device to bring your sounds everywhere you go, the Mooer Radar may be a very good option for you…

Mooer Radar : presentation

The pedal weighs approximately 150 grams and the box contains :

  • The pedal
  • The power supply (which is almost bigger than the pedal itself)
The Mooer Radar and its power supply

The complete description of the pedal and its documentation are available here : http://www.mooeraudio.com/product/Radar-51.html 

It can be used by guitar players and bass players.

You can also control it from a software running on your Mac or you PC, connected with an USB cable. The software is available in the Download / support section of Mooer’s website  http://www.mooeraudio.com/download.html .

The Radar download entry will present you with the different download options:

If your pedal firmware is not up to date yet (latest firmware is 1.2), the Mooer Radar software will allow you to execute a procedure to upgrade the pedal when connecting the two.

The pedal connectivity includes:

  • a guitar input jack (6,35mm)
  • a jack output for line level out, 6,35 mm jack (470 ohms)
  • a headphone out , with a 3,5 mm jack (10 ohms)
  • a 12 volts power input (300 ma required by the pedal)
  • a micro usb connector for remote control, IR upload and updates (the usb cable is not part of the package)

The technical capabilities of the pedal are the following :

  • Sample rate of 44,1 Khz, 24 bits
  • frequency response : 20 Hz to 20 kHz
  • signal to noise ratio : 100 db
  • latency : 2 ms
  • IR length : 23,2 ms (1024 points), version 1.0 of the firmware was limited to 11,6 ms (512 points)

The pedal embeds factory defined IRs, and you can upload your custom IRs to the pedal. 36 presets are available, with 30 cab/IR slots.

Connecting the Mooer Radar pedal

This pedal is an IR loader : it brings a guitar cabinet simulator that you can use for practice, for live or for recording. The two screenshots below present an overview of the connections and usage scenarios of the pedal.

Practice or live

Using headphones only allows for silent playing and recording if you use a preamp/distosion pedal or a load box with your (tube) amp. Please note that the depicted guitar amp is a Laney Ironheart Studio : this specific amp has an embedded dummy load and does not need a load box as such (the Captor load box presented here is redondant for this specific amp but you will need such a load box if you want to route your tube amp output to the line level entry of the Radar and avoid to connect a standard guitar cabinet).

Using the Radar for recording

In this second screenshot, we present a scenario where the output of the Radar is sent to a DAW through a sound card : this pedal may be used for tracking, recording or reamping…. While using the Radar pedal for recording will absolutely work, you may also want to investigate the use of a software IR loader for recording scenarios if you already own a DAW. This may provide additional flexibility and possibilities in recording situations.

Get started

Power on ! It boots in 15 seconds, approximately. The small screen offers a good readability, is quite bright, and is nice to use. The single rotary / push button controls everything.

In default mode, the current preset is displayed:

The commands are simple and straightforward :

  • on the main screen (preset display), turning the rotary button selects the previous or next preset
  • one brief click selects the master volume setting (main out and headphone). Another click and the pedal goes back to the main display screen
  • a longer click enters the preset parameter settings screen
  • a long click (3 seconds and more) sets the pedal to bypass. Then, one standard click deactivates the bypass.
Master setting
Bypass on

When entering the preset settings mode, you will be navigating through 3 screens :

  • one for power-amp settings
  • one for the cab selection, the microphone selection and position settings
  • one for the equalizer parameters
Power amp settings
Cab selection and microphone
Eq settings

The Mooer Studio for Radar software can help you in the configuration of the pedal : the point and click interface of the software will allow you to navigate faster in the different parameters and configure the pedal in an easier way (less navigation between screens and parameters):

Radar Studio : cab selection

The available microphones include some of the most classical ones : Shure, Sennheiser, Neumann…. I discovered a few microphones there for the first time, as I had never had before the opportunity to use IRs based on Rode, Marshall and AKG microphones :

  • Sm57 : Shure SM 57 Dynamic
  • Sm58 : Shure SM 58 Dynamic
  • Md421 : Sennheiser MD 421 Dynamic
  • Md441 : Sennheiser MD 441U Dynamic
  • U47 : Neumann U47
  • U87 : Neumann U87
  • RodeNT1 : Rode NT-1
  • MXL2001P : Marshall MXL 2001P
  • MXL2003 : Marshall MXL 2003
  • C3000 : AKG C3000
  • C4000B : AKG C4000B

I really enjoyed the balance of the U47 and U87 for metal sounds !

For metal heads and rock players, the cabs of interest are, IMHO :

  • Marshall 1960A Green back
  • Marshall 1960B G12T-75
  • Marshall 1960B V30
  • UK.Citrus 4×12
  • Orange ppc412
  • Soldano 4×12 Lucky
  • Soldano 4×12 Slant
  • Mesa boogie recto standard
  • Mesa boogie recto traditional
  • Diezel Rearloaded V30
  • Diezel Rearloaded G12-65Heritage

These factory cabs are globally good, and recorded in a neutral – flat mode : they will allow your amp or preamp signature to go thru and be correctly transcribed or, let’s say, reproduced. Take this with a pinch of salt : I tested the pedal only with distorted sounds and I mainly used the metal cabs. The cabs globally do not sound overly harsh, though the LPF is often set to a relatively low value in the presets (5 Khz).

The microphone position can be set with two parameters :

  • C-EDGE : from 0 (center) to 30 (cone edge)
  • Distance : from 0 (nearest) to 50 (farthest)

Power amps

4 power amp simulation are available, 2 for an American sound, 2 for a more Bristish type of sound :

  • 6V6
  • 6L6
  • EL34
  • EL84

Three parameters allow you to adjust the power-amp simulation (level and bandwidth of the effect) :

  • input
  • presence
  • output
Power amp settings

In my experience, the power section is a must have and must use with this pedal, especially if you are using an amp FX Send connection or a preamp pedal. These power-amp simulations are actually simple to use and give great results. This section is quite critical in the overall sound, and you will get the best of the provided cabs by tweaking these parameters a little bit. This section defines as well the overall volume of the signal that will be sent to the next sections of the pedal : cab/mic and eq.

The embedded EQs

Three equalizers are available :

  • a guitar graphical equalizer (5 bands)
  • a bass graphical equalizer (5 bands)
  • a parametric equalizer (4 bands)

The equalizer section can be turned off (by the way the power-amp section can also be turned off). You can adjust the frequency bands and you can add or remove 15 db. On the parametric equalizer, you can modify the Q factor.

Two filters are available as well, which is really nice :

  • HP : it is the high-pass filter, it can be turned off or set between 0 and 500 Hz
  • LP : it is the low-pass filter, can be turned off as well or set between 20 Khz and 3 Khz

The slope is not mentioned in the Mooer documentation

A few samples with factory IRs

Edit April 09/2020 : listening back to the first samples I recorded with the pedal, I figured out that something went wrong in the original recording process. So I changed my recording setup and managed to get samples which are actually way closer to the sound produced by the pedal.

The following samples are captured with the following signal chain :

-Guitar – Maxon OD9 – Revv G4 blue channel – Mooer Radar – sound card – Logic ProX. No processing in ProX, excepted an HPF on some of the samples.

Using third party IRs

Uploading 3rd party IR can be done by using the Mooer Studio for Radar software : on the Cab section, clicking the “+” button allows for IR upload, and the “-” button reverts the slot to the factory IR. I have been able to test an IR from OwnHammer Heavy Hitters pack and one of my own IR (50 ms) : the Mooer software has probably truncated the IRs to 23 ms but they ended up uploaded on the pedal. I did not perform extensive tests on this : contact and check with your IR provider in case of doubt.

The pedal is simple to use and provides a pretty good sound quality for the price. The default cab selection provides some good IRs for metal guitar players.

A few points worth noticing :

  • Mooer does not provide information or software to create IRs in the pedal format (or I was unable to find it) : only classical 3rd party IRs can be used. A custom IR is then using a slot that is actually able to handle mutliple IRs in the Mooer format (at least more than 11 given that you can have up to 11 mics and multiple positions). Being able to create IRs in this format would allow users to take advantage of the limited number of slots…
  • A far as I know, there is no Mooer IR store, and no 3rd party IR available in Mooer format
  • There is no preset volume control, only a master volume : some users may lack this feature, as switching from IR to IR (mic to mic, cab to cab,…) can drastically change the output volume : watch out and protect your ears when playing with headphones.
  • A real-time level meter would be welcome : you have to adjust your levels by ear. The screen will display a saturation symbol if your signal overload the pedal (and you will notice it, anyway, as the signal will clip)

The Mooer Studio does the job, but remains very simplistic, the UI is minimalist and the ergonomics could be a little bit better. A few minor bugs here and there : some reversed up/down controls or the inability to enter directly a value for the HPF and LPF.

A few other points :

  • Import / export of presets work but do not embed the IR
  • IR names are truncated to 10 characters : rename your IR files or write down which IR you uploaded to which slot
  • The power-amp section is critical to get a good sound from the pedal. It works well and does a pretty good job : it will be handy when using preamp pedals connected to the Radar.

An ultra compact pedal with a very decent sound quality for the price, together with a good set of features (power-amp, mic placement, equalizers) : you will have no excuses to not start using IRs !
