The New Cornerstone of the MG Range
A direct evolution of the best-seller MG-300, the MG-300 MKII pushes versatility further without sacrificing simplicity. It retains the acclaimed sounds of the first version, adds the Shimmer reverb for airy textures, and introduces scene management within a single preset for instant live changes. Its expanded IR section and modernized connectivity cement its place at the heart of the NUX lineup.
Who Is It For and What Are Its Uses?
Ideal for beginner to advanced guitarists seeking a compact
all-in-one unit for headphone practice, home recording, or stage performance. Covering a wide spectrum from
blues/rock to
metal, as well as
pop and
ambient/worship, the MG-300 MKII adapts to many styles. Whether direct "Studio" to PA/FRFR, in front of a combo, or as an insert return, its output modes suit every context. The 3 scenes per preset allow instant switching between clean/crunch/lead tones during a song.
Time-Saving Controls and Features
Clear LCD screen, two assignable footswitches, and built-in
expression pedal to control wah, volume, or any parameter. Fully
reconfigurable effects chain (free placement of blocks, including Patch Level). Built-in tools:
tuner, looper synchronizable with the drum machine, tap tempo. Via USB-C, the MG-300 MKII becomes an audio interface with convenient routings (Normal, Reamp, Dry Out, USB Loopback) and can be edited with the
QuickTone Editor software (patch, IR, and scene management).
Sound
The TSAC-HD engine delivers a sharp attack, dynamic responsiveness to guitar volume and touch, sparkling cleans to tight modern saturations. The cabinet IRs and choice of microphones/positions add depth and realism in both the high and low spectrum. The Shimmer reverb adds an ethereal dimension perfect for pads and atmospheric intros, while compressors and EQ ensure prominence in the mix without harshness.
