Push-button channel switching provides for smooth and uninterruptible transitions. Integrating the FDD technology and analog tone circuitry, the amp gives authentic Marshall sound and feel.

To create a killer tone rigs you’ve always imagined, you can mix them with digital effects and speaker damping function.

One of the outstanding features in this amp is how the power stage combines with speakers, making their behavior to vary depending on the frequency being played.

All the MG range successfully imitate this advantageous valve amp qualities utilizing the Frequency Dependent Dampening technology by Marshall.

The FX loop ensures you don’t run through extra cabling, jacks, and circuitry when you’re not using the pedal. If no single loop is engaged, it goes from the switcher to the amp, most likely with buffer in between, to ensure your tone makes it from the board to the amplifier in good shape. A good FX loop runs effect in line as though everything is in a row.

Negative Aspects

The amp is perfect for classic rock kind of stuff. If you plan on playing Metallica or Megadeth, it’s not the amp for you. It does not have much gain, but the clean channel, on the other hand, is excellent. If you feel like playing heavy metal, you might have to rethink it.

Mixed reaction concerning the manufacturer support. It takes long to get your amp repaired and shipped back to you.  You’ll have to put a noise gate pedal on the amp when using OD2 channel to minimize the buzz. M ixed reaction to sound quality. It has some slight delays on the adjustments


Despite the downsides especially concerning the manufacturer support, the amp rocks, it’s sound is super, especially for an amp that’s not tube. It’s got killer sound effects. You can crank Marshall MG100HCFX 100W Head with MG412CF 4×12 Cab up and click on dampening for a warm tube sound.
