Marshall MG250 DFX Guitar Amplifier

Marshall Amplification is a British company famous for their guitar amplifiers – some of which go to eleven. For nearly 50 years, the trademark Marshall ‘crunch’ distortion continues to remain one of the most popular rock signature sounds.

Out of the box

My first impression was “IT’S A MARSHALL,” need I say more. With all Marshall amps, the first thing you need to know is that all Marshall amps need to be dialed in right in order to get the tones you are looking for. These are not just amps that you can turn a few knobs, turn the gain all the way up and hope for good tone. Marshall’s have very sensitive EQ’s and react noticeably different to the various guitar pickups and guitars out there. If you take the time to play around with them, you will find that all models of Marshall amps can rock the house!

After playing around with the Marshall MG250 DFX I found that you can get some amazing old school Marshall tones as well as nu-metal crunch. The MG250 DFX comes with onboard effects that are smooth and very usable. The MG250 DFX effects include chorus, chorus/delay, delay and flanger. reverb is on a separate pot for better fine tuning. The MG250 DFX has two channels, a clean and an overdrive channel. The clean channel has an excellent clear tone with the capability of reaching that classic Marshall crunch tone when the clean gain is cranked up to 10. The overdrive channel can range from dirty overdrive to nu-metal distortion. A great feature of the MG series is the FDD (Frequency Dependent Damping) system. This feature produces a brighter fuller tone much like a tube amplifier.  The MG250 DFX is a solid state amplifier with all the goodies.

The Specs

The Marshall MG250 DFX is a 100 watt (2 x 50 watt) amplifier with two channels (separate EQ per channel). The MG250 DFX utilized a combination gain/volume pot on the clean channel as well as a bass, middle and treble pots. The overdrive channel utilizes a separate gain pot along with bass, contour, treble and volume pots. The contour pot acts like a separate EQ on its own changing the tone drastically from bright to scooped mids tone.

The MG250 DFX on-board effects include chorus/delay, chorus, delay and flanger with a separate effects volume pot and a separate reverb pot. The MG250 DFX has a master volume pot to balance out both clean and overdrive channels. The MG250 DFX contains a frequency dependent damping button as well as an emulated line out/ headphone jack on the front panel. The MG250 DFX also has an effects loop line in and line out on the backside of the amp. The MG250 DFX comes with 2-12” speakers specially voiced for this series as well as the MG Marshall footswitch. The MG250 DFX dimensions are as follows (671 x 489 x 275) (mm) and weighs 48.5 lbs.

The Low Down

The Marshall MG250 DFX guitar amplifier is a great buy for the money. When dialed in the MG250 DFX can deliver a wide variety of Marshall tones. Everything from classic style crunch to nu-metal distortion, and everything you could need for live performance or practice. The MG250 DFX is brutally loud and crisp sounding at high volumes. The on-board effects compliment both channels perfectly. The MG250 DFX is the perfect amp for anyone looking for monster tone but doesn’t want to lug around a half or full stack. Not all of us have roadies! All in all this is a great amplifier and I would recommend it to anyone on a budget, or not.

Pros: Great tone, on-board effects, effects loop, 2×12” speakers, loud punch, Can be picked up for a few hundred bucks.

Cons: Discontinued.

MSRP – $499 US

  • Too bad Marshall discontinued the amp. Wonder why? But the good news is that you can still find them as new old stock at music stores if you search around. Also try the online used market. You can pick them up in “like new condition” for $200-250.

    They discontinued this model because they came out with the MG100DFX head. So technically it was only discontinued in the 2×12″ combo. You can still get the MG50DFX which is a single 12″ speaker or buy the MG100DFX head and 4×12 cab. I think this model should still be available, bad choice to discontinue it. However Marshall has so many different amps nowadays that they can afford to drop a similar amp and promote the other ones.

  • I haven’t come across this amp before. It certainly looks interesting. As you say it is a pity they discontinued the combo version
