Marshall has always sought to provide outstanding tone to guitarists of every budget, and with the new MA Series, all-tube Marshall tone is now more affordable than ever. The MA50C 50W combo was carefully designed by Marshall's R&D team using the same basic principles as all Marshall amps”to deliver colorful, dynamic, unmistakable Marshall tube tone in a road-ready package.

Attractive Looks
The aesthetics of the MA50C head have been specially designed to create a look that stands apart from most other Marshall amps, while still retaining the essence of what people have become familiar with for over 45 years. Two orange LEDs illuminate the interior of the unit, highlighting the power tubes. This effect is visible through the fret cloth where the trusty white script logo is mounted onto a solid piece of transparent Perspex.

Tube Power And Tone Simply Executed
The MA50C is powered using the traditional Marshall mainstays of ECC83 double triode tubes in the preamp, and EL34 pentode tubes in the power amp. The layout and controls are kept simple, allowing you to explore unhindered the full potential of the all-tube tone within. The MA50C has separate EQ stages for both the Clean and Overdrive channels so you can optimally adjust each one without compromising the other. A 12" Eminence AX-75 speaker delivers all this great tone to awaiting ears. An extra benefit has been provided in the form of a tube-driven Boost function on the OD channel giving you, for example, a solo boost with more volume and gain. The amp also contains a spring reverb for use with all channels within the amp.

Intuitive And Practical
The MA50C combo was designed with the flexible control demanded by today's players in mind, but with a streamlined feature set to keep it cost effective. Whether in your own home or gigging, setting up the sounds and relative levels is very easy. The supplied footswitch assists live performance letting you toggle between settings like Clean to Overdrive, Clean to Boosted Overdrive, and Overdrive to Boosted Overdrive, ensuring maximum versatility.

Even though the MA range is designed as a no-frills, all-tube guitar amplifier, Marshall included a couple of extra features that allow for even more versatility. In addition to the all-tube preamp and power amp tone, MA amplifiers are equipped with an onboard spring reverb tank for an extra dimension to your sound. With the front-panel level control you can easily dial in how much you need for your own taste. All MA amplifiers are also equipped with a serial external effects loop for guitarists who want to add effects units into their sound. The nominal level of -10dBV is suited to stompboxes primarily, but not exclusively.

from Franklin, TN

This amp is absolutely great, especially when you consider the price. The cleans are nice and honest, the overdrive screams like it should, and the boosted overdrive is a great feature to give your solos some extra oomph. The spring reverb isn't great, but then again it's a Marshall, not a Fender. You may feel the need to use a delay or reverb pedal instead. All in all, though, it's a high-quality Marshall amp that delivers all the goods at half the price.

Great amp

By Jamie

from Kuala Lumpur, Malaysia

This is a great amp! I'm not sure whether it's UK or American made, but I don't care! The clean channel is calm and soothing, but not as shimmery as I would prefer (I REALLY love the JCM cleans). But the overdrive channel is great! The gain boost button works great cuz it gives me all the gain I need without any distortion pedals at all. The resonance knob it GREAT because it gives me the low end punch for my chugging metal stuff! It is also a very versatile amp (it can play stuff like AC/DC to Van Halen to Bullet for my Valentine to Slayer) so many tones are achievable. I haven't found out how to achieve Eddie's "brown sound" but it can do classic rock well as well as metal and heavy metal. It is also not very noisy unlike the Peavey Valveking my friend owns. The stock tubes are pretty great, so it'll sound great when you first buy it. It is also loud! But if you plan on gigging in stadiums, you should consider either the 50W head or the 100W head. If you need a really good TUBE amp that can play many sounds and you're looking for the classic Marshall tone but don't have the money to afford a JCM or JVM, this is your amp! Never again will I play a solid state amp!

Amazing amp for the money

By Francisco

from Menlo Park, California

I am a hobbyist guitarist who has been self taught for 3 years or so. Specifically this amp was my FIRST tube amp ever over the spider iii amp (which was a great practice amp). The sound that comes from this amp is truly surreal, the ability to switch between clean and dirty with just the base overdrive from the amp is absolutely amazing. It gives you that heavy overdrive that rivals the best of distortion and it has that beautiful Marshall crunch that is signature in Metallica like bands. I normally don't write reviews for products, but the quality of this amp is amazing. If you are like me and looking for an amp upgrade from a solid state amp, then this is a fantastic amp to consider for the price. Trust me you will not be disappointed. If you can afford a JVM or others, go for those, but if you can't go with this!

A Different Approach


from Lansing, MI

This amp is not an exact clone or replica of a more expensive Marshall. It is an independent style and sound was created by Marshall with the gigging artist in mind with a relatively limited spending limit. I would compare it to Fender's Hot Rod Deluxe series. The Clean tone is remarkable. Where the popular opinion differs is the overdrive channel. Like most tube amps, becoming familiar with the settings is important to finding what you are looking for. It responds heavily to adjustments made to your guitar and pedal board, which should be used to your advantage. The negative reviews seem to be from people who didn't spend enough time getting to know this amp or those hung up on where it was made. Let it speak for itself, it is a good choice in it's class.

Nice Amp. Nice Price

By Matt Passow

from Phoenix AZ

This is my first all valve amp and I'm loving it. The sound is so much better than a solid state. This may not sound like a JVM, but for the price it is well worth it. If you are looking to make the jump from solid state to a valve amp, and you don't want to pay an arm and a leg to do so. I highly recommend this amp as the way to go.

a box of bees (buzzy, fuzzy, and shrill)


from Salt Lake City, UT

I gave this amp 1 star for the following reasons: 1) The foot switch is useless for live applications. It has a slight delay after the switch is pressed before the channel or boost actually changes. 2) The amp is very noisy even when nothing is plugged into it. 3) Its mid and lower gain crunch (ala AC/DC, ZZ top) is lousy, lacking note separation and dynamics of soft vs hard attack. It can mimic some heavy 80s rock such as Ratt, Motley Crue, etc. But even then the sound was too shrill for my tastes. It sounded more like a solid state overdrive than a tube. 4) The clean channel also lacked the warmth of a tube amp. If I was blindfolded and someone played this amp without me knowing which amp they were playing I would have guessed it was solid state. 5) The reverb is perhaps the worst of all internal reverbs I have ever heard. It lacked depth. 6) The overall sound in both the clean an overdrive channels was way too tinty, shrill, and piercing. I had to put the treble setting at 0 just to make the sound tolerable. This is by far the most disappointing amp I have ever owned. I bought it because it said "Marshall" which turned out to be a big mistake on my part. Admittedly, Marshall makes good high end amps. Admittedly, Marshall never marketed the MA50C as anything but an entry level all-valve amp. However, I expected more from Marshall than what they produced in the MA50c. I wasn't expecting a JCM sound but I was at least hoping for a moderately decent tube sound. While I am disappointed in the MA50c I am very pleased with the customer service at Guitar Center. I returned the MA50c and exchanged it for a Line 6 Spider Valve MKII which kicks this amps butt in every way.


Great amp for the price

By Oscar Sanchez

from NY

This was my first tube amp after playing a solid-state for the first three years of my guitar-playing life. I bought a re-stocked amp so it was even cheaper than normal. While the amp doesn't sound as great as a JCM or other high-end Marshalls, this amp is certainly worth the money. It's definitely gig-worthy and loud enough on overdrive for some nice soloing. It took me a few days of playing around with it and my Strat to create some nice tones. I'm planning to buy the new 2012 LP, which will undoubtedly sound great through this amp. The amp itself can generate enough distortion for most styles except the heaviest of metal. The cleans channel is not quite up there with VOX but its great, nonetheless. Frankly, my only complaint had to do with the construction of the input jack. After about 2 months of using the amp, the input jack unloosened and fell into the circuit board. Fortunately, it wasn't hard for me to repair the problem with a Phillips-head screwdriver and some glue. But it was an annoying process to unscrew everything and fix that one little part. I don't think a high-end Marshall would have that problem. The amp itself is pretty well-constructed and looks able to handle some abuse. After my simple repair, the amp is fine now. In summary, the amp is not quite as well constructed or sonorous as top-of-the-line Marshalls but it's still a surprisingly good amp that will even make you sound better.


Decent but limited tone

By Clinton Medicine Crow

from San Diego, CA

Got a great price on a like new factory reconditioned unit. Has the "Marshall" tone for sure but in a very limited way. The distorted tone is very much a "modern" metal type tone so if that's your thing not a bad choice. If you want a little more of a classic 70's thing, your probably gonna find this one a little lacking. The real bright side? Has an awesome clean tone, really nice. Sounds good with a Strat or Les Paul and sounds just as good as the old american tube amps. Actually sounds quite decent when you use an overdrive or distortion box through the clean channel. Seems to be a good solid "no frills" amp though for the most part. Looks like the savings are mostly in the use of lots of plastic and cheap labor in Vietnam. If you are really on a budget this is going to work fine for you but if you must have the best of those Marshall tones, save your money and step up to one of the higher end offerings.
