An affordable little powerhouse

The Marshall MG30GFX is a 30-watt, 1x10" combo guitar amplifier designed for those just starting out on the electric guitar. Its four channels - Clean, Crunch, Overdrive 1, and Overdrive 2 - provide a highly usable range of basic sounds that can be further customised by the player using the effective three-band EQ. The MG30GFX's tone-shaping capabilities continue with its onboard digital effects section, which includes essentials such as reverb, delay (complete with a tap-tempo button), chorus, flanger, octaver, and phaser. The amp additionally features a headphone output with cab simulation, and its AUX input (which like the headphone input is also in 3.5mm mini-jack format) allows the player to jam along to their favourite tracks in complete comfort - and thanks to the inbuild tuner, they can also silently check their tuning quickly and easily whenever they want.

Marshall sound, Marshall looks

The MG30GFX features a typical Marshall-style control panel that is intuitive and flexible enough to allow the player to dial in virtually any desired tone quickly and easily without needing to consult the manual first: The basic sound can be selected via the "Clean/Crunch" and "OD-1/OD-2" buttons and tweaked using the three-band EQ section. The user can then enhance their sound with the onboard digital effects and, when they have got it just right, store their setting by pressing the "Store" button. But no matter which of the four channels the player selects, they can always expect genuine Marshall tone with enough volume on tap to cut through in a band context and for small gigs thanks to the MG30GFX's 30-watt power stage and 10" speaker.

A true Marshall on a budget

In spite of its impressive wealth of features, the Marshall MG30GFX comes at a surprisingly affordable price that will make it particularly interesting for beginners, who even on a restricted budget still get an amplifier with all the trimmings that combines the legendary Marshall sound with excellent ease of use and sufficient power (as well as a big enough speaker) to handle rehearsals and even small gigs. Another major plus for those who don't have limitless money to spend on gear is of course the MG30GFX's easy-to-use onboard effects section, which provides the most essential effects without the need for pedals.

About Marshall

Marshall, the manufacturer from Milton Keynes in Great Britain, is an indispensable figure in the world of electric guitar. The tube amplifiers of company founder Jim Marshall († 2012) have been writing Rock music history since 1962 with names like Pete Townshend, Jimi Hendrix, and Eric Clapton. The classics of the JTM, JMP, and JCM 800 series are still highly sought-after today, as they shaped the sound of overdriven and distorted electric guitar more than any other product. To this day, the combination of the amp and 4x12" cabinet - the "Marshall stack" - is synonymous with the energy and power of the Rock music genre. Alongside these landmark achievements, however, Marshall has always kept its finger on the pulse of the times and a close eye on the needs of up-and-coming musicians.

From bedroom to stage

For one amplifier to handle everything from jamming along to backing tracks at home using headphones through to band rehearsals and even gigging, it has to be designed with immense flexibility in mind, and the Marshall MG30GFX fits the bill perfectly thanks to its four highly usable basic sounds, effective EQ section, and versatile onboard effects. Even recording to a DAW is possible with high sound quality thanks to the amp's headphone output with speaker emulation: All the user needs is a 3.5mm to 6.35mm jack adapter and they can run the amp signal direct to their computer - no microphones necessary!

I was surprised how poor this amp was.
Chocky 04.05.2019
I got the amp as a simple practice amp with a few features and a few Marshall tones. I also have a Marshall Origin 20 sitting next to it and a Yamaha THR10 on my desk. Comparing the three, I didn't expect the MG30 to be equally as good as the others, but I was surprised at how poorly it stacked up across the board.

Turning the amp on, it's noisy. At the same volume/gain levels the other two amps are not. The Yamaha lead channel is based on a Marshall plexi, so I turned on the MG crunch channel to find a comparable tone; one week later, I'm still looking.

Sounds: the MG sounds poor when compared to the Yamaha THR10 Marshall sim - not just a bit down, it is poor in comparison - this shocked me. The Yamaha is $300 against the $200 of the MG, but I expected the MG to at least do the Marshall tone as well as the Yamaha - it cannot even get close; extremely disappointing.

Effects: it's hard to dial in effects on the MG due to the way 5 effects use the same knob, so the actual linear adjustment space is tiny - this is a problem because finding a good sound takes a lot of tweaking. Again, the effects sound poor compared to the Yamaha THR. The reverb has two styles and is pretty light, but it's ok - it adds a bit of depth and space to the sound. I have many pedals I use with my Marshall Origin (such as a Wampler delay, TS808, Keeley reverb, etc), and I didn't expect the MG effects to be that good (and they are nowhere near), but I expected them to compare ok to the built in effects of the Yamaha THR10 - they don't.

Build quality is fine.

Late at night, I want to play the MG because it has a headphone socket and an audio in, but just turning the amp on is so noisy (a lot noisier than the 20w tube amp sitting next to it - not turned on at the same time - that I'm put off and just plug into the Yamaha instead even though it's more uncomfortable to play at my desk.

4 channels is good, but it takes a long time to find decent sounds, so the fact there are 4 memory presets is useful - you need them; once you find a sound you like on a particular channel (this may take 20+ minutes) then press save and don't change the settings of the amp again on this channel (although, if you do the tone stays at the set position when going off and back onto a channel) - this is kinda ridiculous, right, that the amp is made as an easy to use non-complex modelling amp, no PC connection required, just plug in and turn a few knobs to get a good sound, but you can't...

I had a Randall solid state practice amp, a KH edition, and it sounded a lot better than this amp.

This is quite cheap, so might be good for a first amp, but even at $200 there are better amps such as a Bugera T5 head with a HB cab - I owned that last year, and it sounded much much better in every way than this MG. I also has a Fender Mustang 20w solid state amp about 5 years ago and it did the Fender sound much better than this amp does the Marshall sound. At half the price, a VOX pathfinder is similar sound quality to this amp.

I was shocked at how poor this amp sounds and how difficult it is to find good sounds - it just reduces your playing time. I will give this away, I couldn't in good faith sell this amp on - and, I'm fond of Marshall amps; I know the MG50/100 heads sound good, I had a DSL 5w which was great once I changed the speaker. Try this amp out in person before buying to see if you like it's qualities compared to other similar amps; if you buy blind on the internet then don't throw away the box, and be sure of the returns process...


A great amp for metal.
eroMorpheus 14.08.2020
The Marshall MG30GFX combo amplifier features a 10” speaker that utilises every single watt of the 30 watts available to you – you’ll hear every note you play in glorious detail. The 30-watt output makes it a great option for gigging smaller venues, rehearsal spaces and for home/apartment use. A headphone output allows you to jam in silence without having to worry about disturbing your neighbours or housemates too! This also makes a great amp for recording as you have a world of digital FX built-in to make use of including Reverb, Chorus, Phaser, Flanger, Delay and Octave effects – all of which can be manipulated via the front controls on the amp.The addition of 2 x channels – Clean and Drive as well as 2 x Overdrive options means you can enjoy everything from clean tones all the way to bone crunching distortion. This is a budget friendly amp for beginners with a world of sounds that professional players heavy metal players and blues lovers will enjoy.


Gives You More Than What You Want

I bought this amp for home use. This solid state 30 watts amp is further than enough for home use, sound quality makes you happy. Because if you have a tube amp you need to use it increasing the volume as much as you can in order to taste the beautiful tube sound, i mean, if you are going to use with low volume, a tube amp can't be satisfying.

The sound of this Gold series of Marshall are pretty awesome according to previous ones.

And the effects on the amp (reverb, chorus, phaser, flanger, delay, octave) are quite satisfying if you don't have effect pedals. But you need a footswitch (which is sold separately) to use them easily (I wish it comes as default but i regret not buying the foodswitch honestly)

As a summary, i liked it so much..


Great practice amp!
HMMR 18.08.2020
Had a 15W from another brand and decided to increase a bit the power to 30W or 50W and overall tone, towards Marshall

If I were to buy another amp though I would probably go for the double 12' MGX 102 if to play smaller gigs or very large practice room. I was strongly tempted to get it instead but it exceeds my needs a the moment. We will meet again 102!

For now and my practice needs, the MG 30 was the best choice balancing power and needs. 50W was also a big temptation just for one tiny detail it can be crucial upon doubt, the power cable...

Sound, looks, general construction, closed case, back to black and gold patterns. Overall quality and foremost, the value for your money since pretty decent amp for less than 180 EU

Enough power to even do small gigs, it almost there but with limitations

-Channels are very nice but minor adjustments are in order to try to reach your favourite tones.
-The power cable is not a plug in cable as in the 50W, nothing to do with sound or specs but always better to be able to plug in a power cable upon need than to have to open the case. If gigs are your thing get the 50W onwards in all cases.

UPDATE after usage.....Sold it to get a Marshall valve state some month ago and I regret selling this amazing Amp, extremely happy with the new one but still I miss my MG dearly. If you have it, keep it no matter what else you have! My choice to sell was due to limited space since otherwise I would have just kept it.
