I cannot use the Gateway app and USB connection together. If my Windows 10 laptop is connect to the amp via USB while the Gateway app is running, it freezes the controls settings in the amp and the app. I still get sound, but I cannot change presets or edit presets on the amp or with the app with the USB connected. I have to disconnect the USB cable to be able to use the app, or the amp controls. If I want to use USB, I cannot use the app. If I want to use the app, I cannot use USB. Any ideas?

I have the latest firmware and latest version of the app. I have tried disconnecting and reconnecting bluetooth connection. I've tried restarting the computer. I've tried disconnectiong Bluetooth, shuting down the amp and the computer, and starting everthing up again. Nothing helps.

Any Ideas of when this Marshall 2X15 Cab was made or replacement value for insurance purposes? I have ported it and since the wheels were missing added Ernie Ball casters. Thanks in advance.

I bought a Marshall Code 50 amp and the LCD display lights up but will not display any text at all.   I want to fix this problem so I can use my amp again!  I tried to use bluetooth with the Gateway app but It won't let me edit my settings on the app it doesn't do anything.  If anyone knows how I can get the display fixed or to read text please voice your answers.   Also the factory reset does not help.  Thank you

HELP followed the promtps cant get it to connect

Where can I find a full list of the factory presents with descriptions of what they are?

Hi all would love someone to make those presets for me as I am useless and unable to do this on my own. Thanks in advance!

Not a question, but I just wanted to say how awesome my new Marshall MG102CFX is, totally rocks. LOUD, clean/crunchy/overdriving amp, perfect for my live gigs, and my home recording studio. These 2x12's and the solid state 100 Watt power amp have proved great, as are the FX's. I loadup my pedal board through the Send/Return loop without issues. I also got the Marshall optional mg4 - 4 button stomp foot-switch, which is needed for live work, and well worth the extra money. Thanks Marshall, you have made another fine product!

Good day,

thanks in advance

I found several presets on MYMARSHALL for Jimi Hendrix and Led Zeppelin and some others while browsing on my PC.  I added them to "my library" and then opened the MARSHALL GATEWAY app, logged in and hit SYNC NOW.  But the 9 presets I selected do not sync with my iphone.  What am I doing wrong, or is what I am trying to do not possible?  Thanks.

Hello.

I bought this combo yesterday. All is good, I like it's sound.

But volume level in headphones is very, very low. I have to turn volume to max to hear something.

Is it bag or feature?

Any suggestions to solve it?

Regards,

Alexander.

When I try to hook my amp to my laptop, a box appears at the bottom of the screen that says code 50 not connected. I'm no computer genius and I'm sure I'm missing something simple but, how do I get it to connect? 

Does the low end of this amp get better after the speaker gets broken in. I don't get to do a lot of high volume playing right now so, how can I speed the process if that's even going to help? 

Although the amp is ok, there are some software/firmware issues. I know Marshall will come back and ask me to be specific, however just look at the forum. I was an early adopter and there hasn't been a application update (last update to app was February 22nd 2017) or firmware update for quite sometime. The problems that everyone have mentioned still exist. 

I feel like we are about to be abandoned?

Let us know if development is still happening or if we should get out now! 

Has anyone had any experience using a wireless system on the foot switch for the code? Just an idea I've had to save another lead across the stage.

I recently bought the pedal and noticed if I switch sounds during a song there's a brief gap in the sound which is something I've never had with a normal pedal board? is this just the way it works? is it defective? is there a fix? if there isn't it's very poorly designed...any help would be appreciated thanks

Code 50 Amplifier.  Recently purchased.

Using the headphone jack, the volume output to headphones is quite low. I have to increase the Code 50 Main control as well as the guitar volume control when I plug in headphones. Is this normal for the Code 50? I use Audio Technica ATH-M30X (47 ohm) studio monitor headphones, as well as AKG (32 ohm) phones.

I do not have this issue using my other amplifier, which is a Fender amp. With that amp, very little volume adjustment is needed when I plug in my phones.

Is it possible to use the 4 button JVM footswitch with a JVM 410c?

I would like to save some pedalboard space.

thanks
