Can be controlled remotely via USB or Bluetooth

The innovative folks at Marshall found a way to let you customize any tone setting in the Code 50 without getting off the couch. Adjustments can be made via USB using the included Marshall Gateway software, or over Bluetooth with the handy mobile app. With this feature you can let the sound engineer change your amp tones at will from offstage, or you can dial in the perfect recorded tone when your Code 50 is out in the live room.

Aux input with headphone out for silent jamming and recording

More than a stage amp, the Marshall Code 50 doubles as a useful practice and recording tool at home. An auxiliary input lets you plug in your phone or MP3 player and jam along, which really comes in handy for learning cover songs and practicing solos. A headphone out doubles as both an option for silent practice and as a natural-sounding output to run straight into your recording platform.

  • 50 watts with a 12" speaker - good for club gigs and practices

Marshall Code 50

It's awesome, I love the Marshall sounds in particular the Silver Jubilee OD tone. The clean tones are great as well. I compared the American clean sound to my Fender Blues Jr and the Marshall's clean tone was very good. The price is great and as usual Sweetwater's customer service was awesome (shout out to Jake!).

The Marshall Code 50 does its Job and More

I'll admit that I initially was looking to get the Line 6 Spider V 120 Modeling Amp since it was the smallest amp in that group that had a 12 inch speaker. The downside was the cost and it did not have Bluetooth capability. Then I noticed the Marshall Code 50 Modeling Amp that also had a 12 inch speaker, has Bluetooth connectivity and the cost was significantly lower. That is the amp I settled on.The Marshall Code 50's 50 watt output was plenty for me and still loud enough to do a gig within a smaller venue. The amp has Bluetooth connectivity which allows you to control the amp from your SmartPhone. The amp's USB connection to a computer enables DAW connectivity. The amp also has 1/8 inch phone input for connecting to an iPod or similar device for music playback. The cabinet design with a closed back is typical of Marshall's excellent sound quality reputation. The modeling presets are awesome and one can modify and save any of them. Don't be afraid to try different configurations to find the great sound that you are looking for. The presets model 14 preamps, 4 power amps, 8 speaker cabinets and has 24 different FX settings. Finally, the LCD display is large enough to be easily read when configuring the amp directly from the top panel controls. And did I say that the sound quality is next to none which is Marshall's strong point.The Marshall Code 50 is an excellent primary amp or great as a backup amp. Its smaller form factor and weight are easily managed when lugging this amp along with you to your gig. Fantastic amp all around!

Very Very Nice. Insane # of Options.

I bought the 25 code when it first came out and really liked it. The sounds of the presets are dialed in really close to the real thing as you can get or what you are looking for.. 100 presets, fury, plexi, jcm you name it it's on there and some. The best part is you can tweak it to your liking from the BT phone app or the controls. It's a closed back which I personally like. Sitting on a hardwood floor you get a nice tight bass and still get all the reverb /whatever you want to dial in. On a stand it's just as nice. The seller for me is you can get as close to the type of amp your trying to get, jtm , jvm, plexi, jcm, blues breaker. It's there. You should hear it miked up. I've been playing for a long time and I have owned them all. 35+years. The switch has yet to be shipped so hopefully that will make it one he'll of a unit. I have both amps on the phone, just turn it on and it connects to the amp that is powered on. You gotta respect peoples opinion, some aren't going to like it but for me this is exactly what I expected and wanted. These things scream and get soft and mellow a few clicks away. I really like the way these are going. Tube sound is there along with many more and you can change every little detail and lock it in to 1 of the 100 presets. Have the mustang. This one goes a step further. $250.00 for all of the tweaks and sounds is a great deal. 50 loud watts, downloads of others ideas on the way. Hey Dan I'm happy, Thanks.

Code 50 1x12

First off I want to say Thanks to Scott for the AMAZING service that he provided, I have been dealing with Sweetwater and Scott for several years and they are top notch when it comes to customer service.I have had this amp for a few weeks now and it has exceeded my expectations, the presets are spot on and the FX are terrific, I have had several more expensive modeling amps over the years such as Vox, Peavy, Orange etc... The Marshall is the most accurate by far at recreating the actual "voice" of a particular amp, FX, cab,'s response to pick attach is great as well as the ability to control all the parameters of the amp from my Android phone. You will not be disappointed with this amp.
