Post-Effects with Core Image Technology
Modulation:

NUX built the popular Mini Core Series and the Verdugo Series (post effects) using Core Image Technology. Now MG-300 provides you with the same sound library - including all the classic Chorus, Flanger, Phase, Vibe, Rotary, Vibrato, and more.

Delay:

If you have tried out the Cerberus or Atlantic, you know NUX's impressive Delay and Reverb sound. MG-300 offers even more new models and algorithms with Core Image technology. It also provides sub-division and tap tempo to make your tone more musical.

Reverb:

Just like the iconic sound of NUX's Atlantic reverb algorithm, MG-300 adds Room for small environment reflection.

Jam ( Drum & Looper ):

60s phrase loop recording time. MG-300 supports NUX Phrase Loop Synchronization with Rhythm - a breakthrough technology derived from the popular NUX Loop Core Stompbox and later the JTC Pro Drum & Loop. Every guitarist has his/her own funky way so a truly versatile drum & looper is indispensable. MG-300 has 8 rhythm styles, each style has 7 different beats. You can play the rhythm then record your phrase loop. MG-300 will automatically amend the phrase to fit the current rhythm BPM.


Expression Pedal
The Expression Pedal can be used to control the volume or the effects.

WAH: Controls the WAH filter.

EFX: Controls GAIN (DRIVE) parameter of OD/DIST. Or controls PITCH parameter of PITCH BENDER.

AMP: Controls LEVEL parameter of AMP.

MOD: Controls MIX level of Modulation effects.

DLY: Controls MIX level of Delay effects.

RVB: Controls MIX level of Reverb effects.

TSAC-HD Pre-Effects and

Amp Modeling algorithm providing optimum sound response and playability

Dollar-for-dollar, the best multi-efx on the market. Our dream was to develop a compact and versatile multi-efx pedal at the right price. We understand that both beginners and working musicians are looking for compact size and great sound at an affordable price. This was a big challenge, and we're proud to say we did it!



CORE-IMAGE Post-Effects

sound library offering you

studio sound quality

User-friendly interface and interactive Quick Tone™

Edit Software

IR (Impulse Response),

USB audio stream (recording interface with re-amp function), and more !

We've all experienced digital pre-effect pedals that belong on the Wall of Shame - especially Overdrive.

Modelers of this kind used the linear algorithm which doesn't provide negative-feedback for dynamic playability.



Enter the NUX MG-300, the modeler that will totally blow your mind!



The pre-effect block beautifully recreates the awesome signature sound of real analog overdrive / distortion pedals.

Pre-Effects

Empowered by NUX TSAC-HD Technology

[TSAC-HD]

WHITE-BOX Amp Modeling Algorithm

What is the most important component in an Amp Modeler?



In 2010 NUX introduced TSAC (True Simulation fo Analog Circuit) with the sole intention of bringing Amp Modeling to a whole new level. The DSP industry has been evolving at breakneck speed, and keeping up can be a challenge. We were impressed that a product like the Fractal® AX-FX had the foresight to use a high-definition TSAC (white-box) algorithm to do its Amp Modeling. So we took note and started development on an affordable modeler with TSAC-HD.

The concept of "Chaos makes the muse" perfectly applies to the analogue circuit. When you tweak the knob, it affects itself as well as other parameters. For a linear digital system, the parameter is independent. The white-box algorithm offers real negative-feedback, increment-by-increment. NUX TSAC-HD replicates the same playability most guitarists prefer in a real tube amplifier.



Building a sky-high priced product is easy. The art of building an affordable product is a real challenge. We priced the MG-300, with a straightforward high-performance algorithm to not only fit this specific DSP platform, but dominate the multi-efx platform in general.

For Cabinet Simulation

Impulse Response

NUX is well-known for Impulse Response technology. Using IR is the most popular way to do cab simulation today. Why ? Because the sound is noticeably more realistic compared to traditional cab simulation.



MG-300 offers 512 sample resolution of impulse response. You can load 3rd party IR files using NUX QuickTone edit software. ( MG-300 supports 48kHz wav format. ) The built-in 25 cabinet IRs combine 4 classic microphones with 3 positions to allow beginners a quick and easy way to jump into the multi effects experience.


Post-Effects
With Core Image Technology

Modulation

NUX built the popular Mini Core Series and the Verdugo Series (post effects) using Core Image Technology. Now MG-300 provides you with the same sound library - including all the classic Chorus, Flanger, Phase, Vibe, Rotary, Vibrato, and more.

You can adjust the MOD position as below:

Delay

If you have tried out the Cerberus or Atlantic, you know NUX's impressive Delay and Reverb sound. MG-300 offers even more new models and algorithms with Core Image technology. It also provides sub-division and tap tempo to make your tone more musical.

You can adjust the DLY position as below:


Reverb

Just like the iconic sound of NUX's Atlantic reverb algorithm, MG-300 adds Room for small environment reflection. Simple operation with great sound is our mission. Try it... you'll love it!


MG-300 supports NUX Phrase Loop Synchronization with Rhythm - a breakthrough technology derived from the popular NUX Loop Core Stompbox and later the JTC Pro Drum & Loop.

Quote from: miggelblast, post: 31043692, member: 225757

I'm on the verge of ordering the MG-300 for playing with headphones and maybe some other stuff as well. Is it possible to bypass the amp sims and IR's and use it purely as a multi-fx in front or in the effects loop of an actual amp?


yes



Although in AMP Effect loop   the AMP  MUST  have separate FX SEND and FX Return Level controls,as the NUX MG-300 input is fixed at  -20dB



The Valeton GP-100 is a bit more flexible in this regard, as it has input level adjustable between -20dB to +20dB , and provides a StompBox Mode

- but many NUX MG-300 FX ( Spring Reverb) are superior to the GP-100 FX , - but the GP-100 has a wider FX palette (touch wah, Bias Trem, etc)

and the GP-100 in Tuner Mode can be configured between MUTE or  Dry signal only - which acts as a clean Bypass i.e FX Off mode.

Hi there,

I'm about to get this unit. I would like to know something I haven't been able to find anywhere:

I want to use the audio interface capabilities to record and monitor 2 simultaneous tracks in my DAW, one with the Nux's full chain panned 100% right and a completely dry DI to use with a plugin in my DAW and pan it 100 % left.

Is this possible with the Nux MG300? I really want a stereo rig through headphones, basically, with 2 independent signal paths mixed.

Not possible on the MG-300

is possible on Valeton GP-100, or Ampero

Oh... What a pity, I love the sound of the demos I've heard...

So, the dual track thing is Not even possible with Asio4all drivers?

Plus, would you say the Ampero can sound as realistic as the Nux?

Nux sounds a bit better than AMPERO or Valeton

Erjimipey

Thanks for your answers. I really appreciate it. I dig the Nux sounds....

So, the dual signal path... Would I be able to do it using the Asio4all drivers? I did it that way with my Boss Katana MkI.... Has anyone tried that?

Has anyone found a way to turn off direct monitoring on this device? While I like the built-in sounds, I also want to use it with VST guitar software.

I haven't found a way to keep it from overlaying its signal on top of the USB audio output.

The "Dry Out" mode almost does what I want, but it still overlays the effect chain path on the output - I want 100% what the USB path is outputting.

ladron

I was able to work around the monitoring issue by using "Dry Out" mode and setting the amp gain to zero. A bit of a hack, but it works.

Some other notes - the unit was completely silent after doing the firmware update. Fortunately, I'd read on another forum to try calibrating the pedal - that fixed it. Not everyone is going to know to try that, though.

In case anyone cares, I tried using it with Linux and Android. Neither worked.

That's interesting. What app(s) are you using? I tried using Audio Evolution Mobile Studio - it recognizes it as a USB audio interface, but fails to record. Using the same app/cable has worked for me with other audio interfaces.

I'm on an older version (8.1) of Android, so maybe something was fixed between 8 and 10? I tested on Linux with the latest kernel, though, without success...

Some more information on this device under Linux. Initially it did not work at all. After working with the lead maintainer of the Linux kernel sound system, I was able to get capture working. Audio playback still does not work, though.
