good morning I purchased a marshall code 50, I immediately updated the firmware to version 1.48, I performed all the possible procedures for connecting to the phone, when I press rev and pover it goes into pairing mode and the blue light flashes but no phone that I have tried and sees it in the devices, is there a solution for this problem?

Dear Marshall team:

I use the Code 25 amplifier, with the Gateway app and the Code series footswitch. The firmware is updated with the latest version available.

For a long time I have been noticing certain problems, mainly:

-The preset settings are changed on their own (sometimes the volume, other times the gain...) They are usually changed to the settings on the control knobs. I load the preset again, and after a while some of the settings are changed again.

-Another problem is that after using a preset for a while, when changing to another it does not change (it stays blocked). It does not respond either by using the pedal or by changing the preset from the app I have to turn off the amp. At first I thought it would be a Bluetooth problem, since I was using the Gateway application, with an iPhone. But now I'm using it with an Android phone and I continue to have the same problems.

Waiting for your comments, receive a cordial greeting.

Eduardo,

The Gateway app on my Android phone has been repeatedly losing connetion to my CODE head in recent months, and attempts to manually reconnect have usually failed. This unreliability is completely unworkable for gigging, so today I have tried to solve the problem through a thorough update and reset ... but now I can't get the connection to work at all. I deleted the Gateway app from my phone, unpaired the phone from the head (by "forgetting" the Bluetooth pairing), and have installed all pending firmware updates. When doing those installations, I noticed that several related to improving Bluetooth operation, so I was hopeful this would solve my problems. So I've gone ahead and carried out the "First connection" instructions on the website, but these instructions have failed at a very early stage. After I press Rev and Power and get the blue flashing light, when I attempt to "Pair new device" from my phone, I get the message "No nearby Bluetooth devices were found". This connectivity problem is definitely at the Marshall end, because I have checked that my phone is able to connect with other Bluetooth devices and it is doing so fine, so the fault is not with the Bluetooth operation of my phone. It seems like there have been some known Bluetooth connectivity problems that you've tried to fix during recent firmware updates, so is this something you can advise me about and give me a fix for? I hope so - there's not much point in you having a really good product if it's unusable in practice.

Hi team. I bought a code 50 a while back and it has been working perfectly fine. Recently however, it would start going quiet while I am playing. This all happened after the new firmware update and the amp is now unusable as it goes silent after as short as just 5 seconds from being turned on. I can get it to work after pressing the bluetooth button and then back, but 5 seconds later then it just goes quiet again. I do now know what to do, seems like a software issue.

Hi,

I've just received my Code 25 amp today. It sounds good but I cannot pair it with my iPhone

It appears as "Headphones" in the bluetooth settings. When tapping on it, my iPhone says "Pairing failed "Headphones" is not supported". 

I've tried with 4 different iPhones (all up-to-date) and got 4 times the same trouble

I've successfully updated the firmware of my amp (MCU 1.47 / BT: V3.2) but it did not fix the issue.

Can someone help ??

Thanks !

Please people, could you help us to developing a new firmware update to fix the DSP AMP simulations for Code 25/ Code 50?

If you could make a fast research on web, you are going to see that this is a very common issue for all Code users. Probably the last firmware updates is affecting just a part of the DSP boards, not all, but in my case and many other people, we can not use the AMP simulations anymore, and the Distortion and Overdrive FX are not ok too.

At least,  could you make the older firmware versions available for tests? I'm sure that most part of the users prefer to have the original and very nice tones than bluetooth running better, better connection with the App, or any other improvement.

Thank you, and please, consider our beg.

I've brand new Code 50 with latest firmware (1.47).

From time to time, the speakers output turns off. I do have to poweroff OR activate bluetooth detection then exit button.

Clearly, this is a Bluetooh issue - and I need a way to turn it off while playing.

Actyally, I've bought the amp and the original pedal switch because I cannot use phone bluetooth while playing.

Please, this is a MAJOR issue, I really need your help on turning bluetooth off.

I have an incomprehensible problem with the code, I try to connect to the combo via bluetooth connection, but the device is not displayed in the list of bluetooth devices, even after pressing REV + POWER the device is nowhere to be found (I checked on different smartphones) and throughout the whole time the code emits strange sounds of knocks from the speakers that are not solved in any way, I updated the firmware several times, this did not help in the end. Has anyone had the same problem, how did you solve it?

In case Marshall decides to do another round of Codes, or for people that want to buy one, here is my bottom line after dealing with this thing for a few years. I had Line 6 experience and wanted a simpler all-in-one modeling combo with a bluetooth app that could do hard rock. The Katana looked like a toy so I bought this.

PROS: Solid construction. Looks great. Good range of amps and effects. Bluetooth app is very good and can tune every parameter. Tones can be downloaded and backed up to/from Marshall site. Amp can sound very good (after a lot of tweaking). The Plexi, American OD, JTM Crunch and Acoustic amps are good. The Guv’nor, Compressor, Chorus, noise gate and all the delays and reverbs are useable. Marshall has done sufficient software updates to correct early issues (bluetooth, tones, bugs). Can be used at bedroom volume with Master on ‘1’. Optional footswitch gives good control. Documentation is good. Updater software on PC works well.

CONS: Other than those mentioned above, all the other amps and effects are bad. This includes the JCM800, JVM and Silver Jubilee. All the cabs are bad. None of the stock patches are usable. You have to make your own. There are user uploaded patches you can try but very few are usable. Learning curve is significant. The amp is too loud. When you turn up from bedroom level to louder, the sounds change and become very boomy which should not happen with a modeling amp. No effects loop. The ‘out’ is a mini USB. Connecting to a computer requires a mini USB to USB or Lightning cable, which is not included. I tried to use the USB to record to Garageband and sound came out but I couldn’t make it sound good. The footswitch also has a learning curve, and like other people I had to have mine replaced. 

ADVICE: Don’t buy it. I bought my Code 50 new from Sweetwater for $299 and now the same version of the amp is $399. If you must have a Code, get the 25 instead. It is cheaper and still absurdly loud. The higher volume available in the 50 is useless because it sounds bad. The extra hundred bucks just gets you painfully loud solid state power amp watts. 

If you do get a Code, upgrade all the firmware immediately. You need to connect to a computer to do this, but first you have to find the cable on Amazon. This is unforgivable.

BOTTOM LINE: I have spent too many hours tweaking the Code. This is what I hated about Line 6. But the Line 6 tones were superior. I never got a good JCM 800 sound out of the Code, after hundreds of hours of work. It’s only “great” amp sim, oddly, is the American OD. Marshall’s own Classic Metal patch uses this, not a “Marshall” sim! The Code is marketed as Marshall technology with amp sims created by Marshall, but it is not. Softube created the software and tones. This is not a Marshall amp. Line 6 Marshall sims are far better.

I have now bought a tube amp. I am keeping the Code because I have mastered it and can practice on it but I would not buy it again, certainly not for $399.

I recently got a Code 50. After a few weeks of using it and learning the my.Marshall website, I realized it did not have any of the newer firmware updates. I updated it with v. 1.47 and now I do not get any guitar sound. I get sound from my phone when it's connected via bluetooth. How can I install the previous version of firmware?

I tried using the foot peddle cable to see if it is a cable issue and strange things happened. I hear some strange music broadcast. Not sure if some neighboring device connected to my amp via bluetooth. Is there any way to turn bluetooth off and on?

I tried doing the factory reset and it does not reset the firmware. Is it supposed to reset the firmware with the factory reset function?

Thanks.

UPDATE: I got this resolved. It turned out to be an issue with the guitar.

Quelqu'un pourrait il m'aider s'il vous plaît je n'arrive pas à connecter mon ampli code 50 sur l'application Marshall gateway il me met ce message: CONNECTION REJECTED You may only control amps you are already connected to for audio output.

Je précise je suis sur iPhone 13 dernière version d'iOS.  Le téléphone lui se connecte sans problème à l'ampli je peux joué de la musique mais c'est tout 

j'ai au préalablement supprimer et réinstallé l'application gateway, reset l'ampli, mis à jour le firmware de l'ampli, déconnecté l'ampli du téléphone et oublier l'appareil Bluetooth, essayer sur un autre iPhone (7)... bref je suis perdu du coup je ne peut en aucun cas faire mes préset depuis mon téléphone et c'est frustrant enfin bref si quelqu'un a une solution miracle je suis preneur et merci d'avance 👌💪

Omg my code 50 as just completely lost any sound no Bluetooth, no headphones, no amp what the flip is going on I've updated firmware hundred times reset amp hundred times and nothing dead as a door nail all lights and functions on amp work OK just no sound please please please help.

Hi folks,

Reently got myself a CODE25, however I couldn't manage to get it connected to my phone. I assume its due to faulty bluetooth module, because when I turned on the amp, bluetooth version field is missing on the screen. The amp also did not show up on my phone although bluetooth pairing mode was activated.

I did follow the troubleshooter but it didn't help.

Updated to the latest firmware (1.46)

Anyone experiencing the same? Any suggestion how to fix this?

I seem to be having the same issues that a lot of people have reported, where I cannot get the Marshall Gateway app to connect to my Code 25. I've only had the amp for about a week and I cannot get the app to see it. ? 

I can connect to the amp via Bluetooth using my phone (Samsung S10, Android 11) and whilst connected, can use it as a BT speaker to play music from Spotify. However, nothing I do seems to get the app to connect to the amplifier. 

-I've updated the amp to the latest firmware using my laptop/web browser. 
-I've followed all the instructions in the Bluetooth Connectivity Troubleshooter to the letter (CODE - Gateway Bluetooth Connection Troubleshooting - my.marshall.com)

No matter what I do, or what order I install/uninstall/connect, the app will not see the amplifier. Everything works otherwise - I'm able to apply Patches from ? using a USB connection - and the amp sounds great. I'd just like to be able to control it from my phone.

I just bought the code 25, and only had it for a few days.  It was great on my iPad for effects via bluetooth, although after  I updated the firware it wont connect to thre app on my ipad anymore, it plays songs from my itunes app but the Gateway app says Im already connected and nothing works to adjust the affects. Im really bummed about this, any word on why this is happening and how to fix it?. 

The Marshall Code 50 I bought losses sound while in use. Turn the power on and off sometimes fixes it and also disconnecting it from the bluetooth device. However, recently I don't even connect a bluetooth device like my phone to avoid it, it still happens. Already tried installing the lates firmware, done factory reset, and still having this problem. I'm from the Philippines, the seller did not reply when I asked for assistance. I also don't know where I could bring it for technical support.

I have a xiaomi redmi note 8 and also have a problem connecting the marshall gateway app to the amp code50.
I can only be connected as if I were listening to music, I even tried to connect it with an otg adapter, it works like that, but there are a lot of problems with braking the application? Please if it is possible to solve this problem.

 And if I tried all variants except one, and that is to uninstall every marshall application to amplify my Marshall Code 50 Firmware 1.4.4 recognize bluetooth connection from which I can control my installed Gateway 1.5.5 of course not just music to listen to But that I have complete control and whether maybe the problem is that the usb is included in my computer, whether to turn it off because I registered everything else. If anyone can answer all these questions I will be grateful.

I have an issue with tap tempo on the Code 25 with 1.45 firmware and wondered if anyone else has the same issue.  The manual says you should "press MOD and DEL selection switches together". When I do that the amp does indeed go into tap tempo mode (tap the selector switch to set tempo), but regardless of how quick I press the buttons or if I hold down one and then hit the other it always switches on the MOD module too. The other double combination switches (tuner and bluetooth) dont do this and work as expected and only switch on those functions without switching on or off any other modules.
