Effects Galore:

Where the MG-400  truly shines is its extensive effects selection. From essentials like noise gate, compressor, and EQ to more adventurous options like chorus, delay, and reverb, it offers a comprehensive toolbox for shaping your tone. You also get a variety of amp models for electric and bass guitars, as well as acoustic guitar simulation for a truly versatile sound palette.

Deep Editing and Customization:

One of the most exciting features is the 10 independent, moveable signal blocks.

Amp Modeling that Feels Real:

The White-box Amp Modeling & Pre-efx algorithm is a clear winner.
