Owner Insights

We analyzed real musician discussions from forums and Reddit to find what players love, question, and tweak about Marshall MG100HDFX.

Use cases and applications

  • Owners use the clean channel with multi-effects pedals for customizable tones, effectively filling a room with acoustic drums and a 300-watt bass rig.

    Source

Value and pricing

  • Commonly sold for around $200 with the matching cabinet, making it a budget-friendly option for practice or guest use despite its limitations.

    Source

User experience

  • One owner appreciated the reverb-drenched clean tones and unique purple tolex, highlighting a niche appeal beyond typical Marshall characteristics.

    Source
  • Some owners find the amp reliable for gigging due to its light weight and loudness despite general criticism of its build quality.

    Source
  • The original matching 4x12 cab is noted to be smaller than standard, affecting sound quality and leading to a "thin" tone when used with non-MG heads.

    Source
  • A user resolved thin sound issues by transferring MG cab speakers into a different 4x12 cab, indicating speaker housing impacts tone quality significantly.

    Source

Comparisons

  • For Plexi-like tones, a Joyo Bantamp Jackman with a 2x12 Harley Benton cab is recommended as a superior choice within a similar budget.

    Source

    Source

    Source

Build quality

    Source
  • The MG series was once notorious for reliability issues, with one user reporting the FX chip broke twice during their ownership.

    Source

Setup and maintenance

  • The amp's chip requires a fan and an open enclosure for adequate cooling; adding a CPU fan can improve its operation.

    Source

Features and functionality

  • The MG100HDFX is known for its clean tones, but struggles with achieving a non-scooped, full metal tone without additional gear.

    Source

Mods and upgrades

  • Installing premium cables and using EMG 57s and Retro 77s pickups can enhance sound quality, even without pedals.

Big Cheap Marshall

This thing is loud. It is a Marshall. Its fans are noisy. It buzzes. It's super cool.

ashmillsap

never buy this

the guy who offloaded this amp on my parents when i was 14 hated it, for years i practiced on it and thought it was good because it was big and because i was stupid and now that i have owned better amps i hate it. i recently tried to trade it in for my most recent amp purchase and the guitar store employee said he could not take it because his manager would kill him. it's not loud for it's size, the tone sounds like shit, there is no headphone volume knob so it is consistently just loud as fuck always. according to the same employee it is a ticking time bomb where eventually something breaks on it that is near impossible to fix. to reiterate, do not buy this.

did you not understand?

Better then it's made out to be

I feel that the whole Marshall MG series gets a bad rap because of the amount of "beginners" or people that aren't the best at dialing in tones using them. But this definitely has the power and versatility to keep up the big dogs, I would recommend using a different cab, or speakers then the normal MG 4x12, they just seem kinda generic and flat sounding, but the head is great.

"Solid" Solid State Amp

Solid state amps often get a bad wrap especially when it is trying to emulate the unforgettable sound of a tube amp. This amp is honestly a great sounding amp, although I mostly use the clean channel, the overdrive channel is unmistakably Marshall in characteristic. The clean channel can be pushed just before the breaking point and when you add overdrive or crunch to it with a pedal it dirties up very nicely. Clean tones are crisp and clear and it is very versatile. The effects that are built in are fine but since I have a full board of pedals I rarely find myself using them. The one effect that I think sounds pretty nice is the chorus effect, it's very vintage and can add a nice layer to your tone. Overall it's a great amp for the price and is a great place to start if you don't have the budget for the more expensive tube amps.

It's "okay"

For a solid state amp, this has been okay. You're not gonna get the best tones in the world with this, I recommend it if you're just starting out and you're looking to go for the starter half-stack route. I really do like the contour knob though, but I would not suggest using the crunch tone on this. Not the best. I've used this in quite a few shows, but I decided it was time to move on, you can do so much better.

Decent enough Amp Head

The Marshall MG100FX head is decent, not the best not the worse. The Crunch tone sounds terrible to me (imo) it lacks definition and sounds like an extremely cheap crunch pedal. The overdrive (although neither the best or worse) and clean sounds make up for it! The EQ controls work nicely and with the added contour control, you get a nice variety of tones out of it. The effects are ok at best....delay, delay/chorus & chorus work nicely, the tremolo effect sounds awful though. Although I've noticed at certain positions that the knobs are on, the effects completely cut out or there's very little 'effect' to your sound, so you have to be quite precise with it..

I'd definitely recommend to anyone, despite its flaws.

blondguru

Hell Yeah

It says "Marshall" on the front, and that's why people buy these. They're not going to give you JCM tones, but the clean channel with a bit of gain is stellar, especially running into a 4x12. The reverb isn't bad either!

chuck_mccannon

It's no Tube setup...

Like the summary states, its no tube amp...BUT if you're fond of Marshall amps and need a soild one on a budget, this is your guy. One setback that I've discovered is that, this amp ony accepts 2 types of footswitches. The "DFX two button" switch (one channel, one DFX) and the dreaded "one button" switch, which shuts down the FX portion of the amp....LAME!! Oh well. Unfortately mine, I bought used, came with the "one button" switch. Not entirely sure if it was supposed to, but who cares. At the moment, i can switch channels hands-free, so with that, I'm satisfied. 3 Stars.

Marshall MG100HDFX Amp Head

It isn't the best thing out there but it gets the job done. would strongly recommend not using the built in distortion, as it sounds thin and not too great, but paired with a few good pedals it works like a charm.

malcolm_mcdowall

Worth it

Super full and smooth for a solid state amp. The OD-1 is worthless and the crunch tone doesn't have enough range in the gain (in my opinion) but other than that I have no qualms. Unless this thing breaks I don't think I'll need a new amp for a while.

"My guitar amp is a Marshall MG HDFX100"

Notable details: this is the amp he has used on every rhythm track in his discography until after his hiatus (the first track NOT to feature this amp is Little Saint Nick, a christmas track released exclusively on the Chillwavve youtube channel. every song from this release forward was recorded entirely with vst plugins). The handful of exceptions being lead guitar on a handful of tracks, recorded instead with di guitar tracks and amp sims, starting around the Devil Faces era. The amp is in a hendrix-y purple, and was purchased at the age of 16 as a gift from his parents. The amp was stolen by a construction worker while he was living in a frat house in college (a decision he discourages others from making), but was returned to him by the police a couple of months after being reported stolen. In that time, the amp suffered damage to the tolex, speaker grille, and handles. He has since sold it to a fan/friend of his (yours truly) in the summer of 2022.
