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.

hola, acabo de instalar el firmware actualizado a mi marshall code 100 combo y ahora no suena ningún preset..

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?. 

Hi!

I bought a Marshall CODE 100w in Oct/22. It wasn't even used 10 times.

Yesterday when I went to turn on the equipment, the amplifier started to make a noise. I thought it might be the cable, but it wasn't.
Even without the cable connected to the equipment, the noise continued.

I reinstalled firmware but it didn't work either. ?

I do not know what to do.

Could you please help?

     hi there , 

    Is anyone else having the same issues downloading user presets from Marshall.com ? I have a code 25 and ive already installed the updated firmware , however im still having issues downloading the presents when i'm connected to my computer.

Poseo un CODE 100 combo con firmware  v1.44  y mi amplificador funciona sin ningun problema, quisiera saber si la nueva version 1.46 realmente trae una mejora respecto al sonido especialmente en los graves, que suenan un poco embarrados, es decir si vale la pena la actualizacion ya que mi amp esta ok, o es solo solucion a problemas de bloqueo como dicen por aqui.?

Hello when I attempt to connect my Code 25 for a firmware update the device is not recognized. It says USB malfunction. I read a post that says I must use a midi compatible cable. Is there a particular way to identify if the cable is compatible or not. If I search the cables I find do not seem to have the proper connector. Thanks

When I use my marshall on the pc I get really strong buzzing when recording and hearing.

I tryed 3 different cables, and updated the firmware 3 times already.

I'm out of options, this turned to be a nightmare to me.

When I select the tuner the display only shows.  C : > | . I think the firmware is M1.1.

Any ideas? Thanks

My CODE25 was repaired by Marshall in September after the amp itself kept crashing and the sound was cutting out. It has now been returned in an even worse condition.

On switching it on, the message 'Hold 'Store' to reset' appears on the screen. I press store and nothing happens. I am unable to access the amp presets.

After 10 minutes the mobile app then also freezes. I have contacted my Marshall dealer who sold me the amp and they have asked me to contact you for a resolution before I can send it back to them.

FYI: I have uninstalled and re-installed the mobile app without any resolution of the problem. The amp is is of no use and even a factory reset and firmware update has not solved the problem. I am gradually losing my faith in Marshall CODE products.

Do you have any solutions?

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.

Hi everyone, I would like to know if the new firmware 1.46, aswell as it fixes the screen flickering on the code 25s, also fixes this on the code 50s, the amp panel flashing together with the button lights when turning on. I don't know if it supposed to be the same problem as in the code 25.

I don't have one yet but already ordered one so I want to know every single thing that could happen. I get a bit afraid when I see negative reviews, so maybe this new firmware fixes most of the problems. 

Regards

Last month (Sept. 2021) I was able to sync my Amp with the Gateway app. Unfortunately, This month/Today the app cannot detect/connect to my amp.  I already updated the firmware of my Code 50. Is there a way to sync it? because I already did what the tutorials said.

Thank you.

Hi everybody

My CODE 25 was working like a charm. After the firmware update there is a horrible whistling high frequency noise coming out from it. It is really bad. 

Anybody can help me out with this? How to roll back the firmare?

(It's not the guitar/cable/ground because I have another amp and I did a test)

Thanks

Hello,

I've finally had time to sit down and play properly with my new Code 25.  There is a lot of fun to be had with this thing, however there are a few things that have became apparent with some of the models. 

Pre-amp models "50s British" and "OD DSL" have really odd low frequency harmonics. To the point where both these pre amp models are pretty much  unusable. The default patches that use these settings are proof of this. To me it appear that its these patches that certain Youtuber's concentrated on when bad mouthing the amp online (and I can understand why). All the models have some amounts of digital artifacts, but these 2 models are unbeleivably bad.

Power-amp model "British Class A" seems too hot to me, not that I have an expert ear, but it is almost impossible to get a clean tone with that power amp regardless of what pre-amp you put in front of it and how low you set the pre-amp gain. 
?
?
?

I understand that no modelling is perfect, but in general these 3 models just don't respond the same way as the other models on the amp.

OK. I'm aware that the Code 25 is a low cost practice amp, and I am fully prepared to just pretend these models dont exist and live with the other much better models on the amp. However in the spirit of reporting issues with the potential of improving the product then if these models can be fixed in the next firmware update (if there is one) then that would be great.

thanks

I had my marshall code for around half a year now and recently something has been going on with it. I use a Macbook Air with Logic Pro X and for some reason everytime I connect my CODE to Logic and try playing something, the second I touch the strings my Bass, Middle, Treble and Volume automatically go to 0.0. I have re-installed the Firmware and did a Factory reset and still nothing changed.

Hello, I bought a Marshall Code 25 a few weeks back and it was working perfectly until I tried connecting it to a PC today using the USB port. The amp is just not showing up anywhere and the PC doesn't detect a new device either.

I've tried :

- Downloading the firmware update software (current version 1.44) to see if it would detect the amp (it did not)

- Using two different cables and two different PCs

- Restarting the amp and reconnecting the cable on both ends

Not sure what I'm doing wrong or what I should be doing next so help would be appreciated.

My brand new Code 50 is crashing after saving presets on amp. The firmware is the latest version 1.44. I applied the factory reset and the presets reset but neither were been helpful to fix this issue. After crashing, there is no output sound.
