Solid choice for a multi-effects pedal.
GiorgosK 19.12.2020
Bought this for practicing, noodling, rehearsals at the studio and possibly a live performance. As a novice guitar player, the MG-300 is by far the top choice for its price in what regards sound quality. It might include less amps, cabs and pedals than other multi-effects pedals, but honestly you don't need anything more! The algorithm used provides a great experience similar to using a true amp and effects, with great sound detail. Paired with a set of monitos speakers and a sound card, you have your complete setup for a home studio! The build quality is good, it doesn't really feel plasticky or cheap for me.

(+) Amazing sound quality for the price
(+) Well thought interface
(+) Comfortable expression pedal
(+) Easy to use accompanying software
(-) No power button
(-) No usb cable included in the package for connecting to PC


So much in a little cheap box
DenisZ 09.09.2021
Many amps and pedals to choose from, great tones, easy handling. The only thing that bothers me is a missing on/off switch, instead of unplug it from the electric socket. But you can buy an extension cord with the switch in a local elect. store for a few bucks.

I was skeptic at first to buy a product from NUX but after a week of using this product, I'm completely in love with it. Though it took 2 months to arrive here in India still I would say the entire wait was worth it. I ordered 2 more guitars from Thomann along with this and the trio sounds amazing.
Trust me this is the best amp modeler and multi fx pedal out there in this price segment.
You can also go in depth by connecting your PC/Laptop/Mac to the MG-300 and explore a ton of sounds.
The best thing about this pedal except the obvious excellent sound quality is that you can directly record your guitar in your preferred DAW without any need of a Audio interface, which saved me a ton as I was earlier going to buy a Scarlett (2i2).
Also the build quality of the body and expression pedal is also good. Though its plastic and not metal, still the plastic used seems high grade and not cheap. The buttons and pedals are also of good quality. The screen is not very big but does the job pretty well.
You can also edit the presets and customize it which gives this pedal a lot of variety and tones to experiment with.


Best Multi-Effect Pedal for under 200 euros!
Mr.Gandalf 24.03.2021
The NUX MG300 Multi-Effect Pedal is one of the most praised pieces of gear in the guitar world since last year in 2020. One of the best features of the pedal is the good amp simulation and the low price. Despite costing only 125 it delivers the goods like no other pedal.

Personally I think the NUX MG300 beats a lot of other multi fx pedals in this price range and above. If you are under the 200 euros/dollar budget this is the device you should consider.

Of course this pedals has limitations but it features more pro aspects than negatives.

I will start with the negative aspects as they are just a couple:

- the pedals is made out of plastic, I personally have nothing against this but some people prefer metal housing.

- there is no USB cable included. Personally I feel that NUX were being cheap on this and they should consider at least when they do re-issues of the MG300 to add a simple USB cable…

-a larger screen would have been better appreciated.

The PRO’s:

- this little unit is capable of putting older Zoom and Boss products to the GRAVE;

- versatile DSP and TSAC sound;

- can load 3rd party IR’s;

- can be tweaked almost how the user want ( the pedals and amps cannot be inter-changed);

- software runs nice on any computer;

- sounds nice in a track mix;

-plenty of amp models and cabinets to choose from when creating the patch you desire.

That being said I am satisfied with this little unit and will looking forward for updates that maybe allow changing position of the patches and maybe and EVH 5150 amp:). I don’t think I will be needing another multi fx pedal at least for a coupe of months as I still have to discover the many tones of the NUX MG300. You can go from Slayer to Nirvana to BB King, as long as you know how to tweak the tones. I am not a fan of the factory presents but you can change them as you please. Good job NUX, let’s see some more updates for the MG300!
