The NUX MG300 is a high performance compact audio modeling processor based on NUX's TSAC-HD (True Simulation of Analog Circuit) algorithm, which delivers high-definition, pro-quality electric guitar tones with realistic feel and playability.A pre-effect block recreates a variety of classic analog overdrive and distortion pedals, while post-effects include chorus, flanger, phase, vibe, rotary, vibrato, delay, reverb and more.There are also 25 built-in cabinet IRs that combine four classic microphones with three positions, and third-party IR files can be loaded via NUX QuickTone edit software. QuickTone can also be used to tweak parameters, download patches and set up USB audio-stream routing.Other features include an expression pedal to control volume and effects, 56 drum beats (eight rhythm styles, each with seven different beats), 60 second Phrase Loop Synchronization and a global three-band EQ. Pre-Effects: Empowered by NUX TSAC-HD Technology. 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. WHITE-BOX Amp Modeling Algorithm: 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.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. The MG-300 uses a straightforward, high-performance algorithm to not only fit this specific DSP platform, but dominate the multi-fx platform in general. 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. 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 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. Simple operation with great sound is NUX's mission. Try it... you'll love it! Jam (Drum & Looper): 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.
