Great Sounding Combo with Player-Focused Features!

Marshall's MG50CFX combo amplifier packs more useful features than you'd usually expect from a 1 x 12" 50-watt combo. It starts with pure Marshall tone, tailored to your liking with the 3-band EQ. The MG50CFX sports four programmable channels - clean, crunch, overdrive 1, and overdrive 2. Dial in your tone, then save it for easy recall later. The tone is lively and in your face, as you'd expect from a Marshall, and you can add even more pizazz with the built-in effects. You get chorus, flange, phaser, and delay, plus a separate reverb that can be combined with any other effect. And you can take complete control of the MG50CFX with the included MG foot controller. If you need an equally capable amp for practice and recording, you'll love the Marshall MG50CFX.

Marshall MG50CFX Combo Amplifier at a Glance:
  • Perfect for practice or studio use

Perfect for practice or studio use

The Marshall MG50CFX packs enough cool features to make practice fun, like built-in effects and a line input for playing along with your favorite songs. It also packs plenty of tone for great recordings. And even if it's late at night, or you just don't have the right mic and space to get the sound you want, you can use the MG50CFX's speaker-emulated line output for fantastic-sounding direct recordings.

Programmable channels

Each of the Marshall MG50CFX's four channels can be programmed to recall your favorite settings instantly. Just dial in your ideal tone, press the store button, and your settings are locked for that specific channel until you adjust and store them again.

Built-in FX

You get four built-in effects plus a standalone reverb with the Marshall MG50CFX. Chorus, delay, phaser, and more are on tap and can be used in conjunction with the reverb. Best of all, the MG50CFX will store your effects settings with your channel settings for instant recall anytime!

Second and more positive review of this amp

I wrote my previous review comparing this amp to my all time favorite rif my Marshall JCM 900 MkIII (Hot Rodded to more than 120 watts with some caps and non stock tubes!) that sat atop a JCM900 1960A and JCM900 1960B speaker cab's full stack. I don't think that first review was fair to this Transistor 50 watt single 12" speaker amp. Since writing my original review I have been playing the Marshal MG50CFX more than any other amp. Why?? Because of the Tone and cranked volume!! When I need a "fix" of Marshall Concert Level Volume and Tone I find myself turning on this amp. BTW I need that fix several times a day. Listen, I really like my Tube amps Fenders for the cleans as does everybody. But there are other tones in this world and Marshall has that "Brown" sound, that creamy hi-gain, fluid sustain that I need to hear. So yes I am talking a different kind of "Tone", but I love Marshall Tone and this amp for less than $400 is giving it to me. Do I still look around for a Marshall Tube amp rig to obtain the Marshall Tone? Yes I do, all the time, but I do not make the purchase. It's not necessary yet because I have the Marshall MG50CFX-50W amplifier in my house. Will I ever purchase another Marshall 100 watt tube amp and a full stack of Marshall 1960A and 1960B speaker cab's? Yes, one day when I am financially secure and free of debt, in other words when I can "easily" afford too. Ha! Or I might purchase another Marshall MG50CFX or possible the 2x12 MG100CFX! I am addicted to loud, wall of sound and Marshall Tone.

Get this one folks

I'm really impressed with what the team at Marshall have done with this new generation of MG series... They did there homework and got it right... I have played just about every kind of Marshall amp there is tube or solid state...I know alot of guys who want to try and find an amp that sounds like a Marshall... Save yourself the frustration and just buy one of these...and they can be hooked up to a cabinet ...please don't listen to the nay sayers... These are great Amps period....


I'm very impressed with sweetwater I've placed a few orders with other online guitar businesses and was less than impressed. With sweetwater every product I've ordered has been good quality, the descriptions have been accurate, I was updated frequently on what my order was doing and every order has been shipped quickly...I'm personally impressed with this amp I wanted something cheaper with a fair amount of power and some cool effects to practice with at home or to perform for a small event if I wanted. My opinion is that is a little extreme for a home amp but will work when you dial the volume in right..playing guitar is just a hobby for me so I couldn't say if it would work for a bigger gig or not but to me it's LOUD and sounds great!

I have had this amp for a year now and if is everything I need.. Practice and small to medium gigs. It has a great sound and simple effects. I play Jazz and Pop and do not need all the "stuff" that comes with other amps. Good reverb and nice phaser and LOTS of volume. It's heavy and I had to get a stand to get it off the floor but fits every situation I'm in.

Perfect Match

Last month I picked up this beauty and was a bit disappointed that it came with the standard 2 button foot switch. After watching the video demo I assumed it came with the programmable 4 button switch, but it does not. I immediately ordered the proper foot switch for this amp and found it easy to program, set up, and use. I am primarily a rhythm guitarist but have been wanting to expand my ability & learn some lead guitar for quite some time, so I've been learning some lead licks on YouTube. I played out with it last weekend and it sounded great! It is the perfect match for my Tele, and the sound techs commented on how great it sounds. This amp is the most amp you will find for under $500 (including the 4 button programmable foot switch).
