Recently updated the firmware for my code 50 and it stopped short of complete firmware installation when I received a pop-up to restart the installation. The amp is stuck at ready to update but now the firmware won't install again. Tried a factory reset but now the amp will say USB not connected...until I reconnect....then it will read... ready for update. Which won't update anymore or resume where it left off. Can I get the original firmware or another way to factory reset? Buttons will not activate anything anymore.

I turned all of the presets off, all i want is a plain Plexi or hot rod amp. I have my own reverb and my own delay and EQ. So I took Marshall Fury Lead which sounds pretty good and turned all the other stuff off...

then when i get app. on my phone turned on it goes and overwrites the preset on the Code 100 head. ??? wtf? Now its noisey and feeding back an out of control.

I cannot risk having an amp that squeals and changes presets like that without me asking it. There are too many settings too much to go wrong. 

I am starting to regret buying this thing.

How do i fix it so that the preset stays in the cloud on the amp and everywhere else forever!.. Until i change it...Can anyone please help with that?

its a 100 watt Code. I just want it to be a dirty power amp, no cab simulator nothing...

thanks, NIck

Hi I have a Marshall code 100 combo amp and wondering how to up date my amp if you can up date my amp? Any help would be apperciated.

Suddenly, Bluetooth stopped working right on my phone (Huawei P series)  while I'm playing...  Amp is updated to latest version and every time i want to change preset surprise! The phone is unpaired, it needs to reconnect again... but guess what? Now the screen on my code start blinking, not red or the buttons either, but it blinks like if loosing power or something... I don't know if it might be an electrical issue or it's just a lose cable inside that needs a check. 

I don't want to always use my phone when playing. There used to be a way to save presets directly in the amp but I can't seem to do it anymore. These past updates have really screwed up the code amp for me. It doesn't seem like any of the support videos are accurate any longer. 

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.

When switching between presets, factory made and made by others - in the app the sound goes from low medium to max, up and down.. 

I use my amp on low in our living room, and its bad for my kids.. scary.

Also alot of fizz crackling when turning the master knob.  Common issue? Is there a fix? Sound jumping up and down.

When the sound is super loud i just touch the volume knob and it goes down in volume to where the volume knob actually is 

Hi All,

I'm getting a fast clicking and humming sound comming through the speaker as I let chords/notes fade out. Tried different leads and guitars but still happening. Fimware is up to date. Doesn't happen when the chord/note is struck...only when you hold the chord/note to fade out.

Any suggestions.

Thanks in advance.

Regards

Don

One thing up front: I love my Code 100C (have two of them), it gives me all tonal possibilities I need, and it never let me down, even not with any bluetooth-issues.

What I really miss is an xlr-out to the mixer or any other possibility "direct-out" other than micing the amp (the headphone/line-out is no option since the amp is quiet then). This lack became annoying, so I decided to get an external multi-fx-board.

Deciding between Helix, Boss and others in the mid-price-range (a Kemper is way beyond what I need) I finally decided for the Valeton GP-200, having read only positive reviews - and the price of 350 € is unbeatable for what it offers. Sound- and effects-quality is great (for my purposesat at least), and going in the return-jack of my 100C spares the 100C-modulation-section to give me the pure sound of the GP-200. And it sounds great with the 100C, no need to change speakers.

Sorry to say: I wouldn't have changed my setup if the 100C had a direct-out, and I'll keep both of my 100Cs, but for the future the combination of the 100C and the GP-200 is my go-to-equipment - although I really like(d) the modelling of the amp (that said again!).

I am a newbie. I bought the Code 50 thinking it would be easy for it to work with pedal amps, like boss blue driver and metal zone. i did not know the code 50 did not "play" well with pedals. I even bout a noise suppressor. 

Anyways I have been googling and found out that there is a "natural" channel.  I could not figure out what that ment. I thought it was a channel I could just scroll to in the preset display. After further looking into it I fould a link to this site with instructions by a person name david doss:

?

I followed the instructions (and I downloaded gateway),  but very low sound would come out of the marshall with the guitar by itself. What I mean is low sound even when volume knob and master knob all the way up. I do get sound when I activate the blues pedal for example but mainly when I adjust the GAIN knob  ON CODE 50. The volume knob does little. Since when is GAIN the new volume button? I thought in the instructions by david doss GAIN was all the way to zero. 

Is there an easier way to connect my pedals to the amplifier? FYI I do not know the difference between amp and pre amp. I am really learning here. So please baby steps. Thanks in advance. 

This actually is a cluster of a few questions that are closely related.

To be able to carry adapted presets with you, you need to save them tot 'Device', the second Icon from the left.
However to link a preset to a position on the Footswitch it needs to be saved to the Amp, the most left Icon when saving.

Most of the time I actually want both, have them in my device and also in the Amp, because of the footswitch.
I have nog found an easy way to do that, both on a one by one and a 'all presets' basis. Anybody?

Because you need the presets in the Amp to link to the Footswitch, every now and then I would like to return the Amp to the original Factory presets.
There are clear instruction how to do that, but when I do, I do not get the Original Marshall Code Factory Settings, but basically what is in my 'MyMarshall'.
I seem not to be able to go back to the presets that were in the Code when I first bought it.
Is there a way to do that, or what is the logic behind it?

It is convenient to take my presets to another Code and use mine, but in a gig, they need to be linked to the footswitch.
So how to deal with that?

Thanks for anyones help!

Bonjour,

Je suis debutant avec une guitare de marque Maison type Les paul!quel preampli? quel Ampli?etc?? dois je selectionner et enregister pour avoir un son le plus clair possible! merci pour votre aide!

When I use my CODE100H with a cab, do I need to turn the cabinet settings off? I've seen several "how to" videos (including ones that have a Marshall tech in them) saying as I'm connected to a cab I don't need the cabinet setting. I've got the CODE4X12 cabinet.

Thoughts?

i brought a code pedal 91010 for my code 25 amp but its not working as it is given on user manual. When i plug in the pedal it just change work as a turn off & on  effects like  modulation , delay etc 

can someone tell me what is the purpose of that particular pedal, im confuse please help me.  

Gateway version 1.5.5 (Wireless Bluetooth selection from the set list, playback selection)
I bought CODE 25 because of its services.
This wasn't made for a concert, but it was great for practice. It took a lot of work to set up the sounds and I was able to play music to my liking with the help of my mobile phone. Now, against my will, version 2 is here, which does not know these things. It was difficult to download the 1.5.5 version again because I like it, but the next day I have the 2nd version on my phone again and this has happened several times. What right do they have to overwrite my phone's settings?
How could I use my favorite amp and settings again to my heart's content, because that's what I paid for, I worked for. If there is a new version, anyone who likes it can use it, but why prevent those who like the old version from continuing to use the system that was created with a lot of effort. This is why I can't return the amplifier! I am waiting for an urgent reply!

Hi Marshall, 

Since your latest firmware update to v1.47 on 1st September and your update to the Gateway app my sounds for my settings have changed.

For example the 00 setting for JTM Chill that should be using the Marshall JTM45 2245, clean setting is now distorted and despite trying to modify it I can no longer get back the lovely clean sound it had as want to be able to use cleans, crunches and distorions for the various modeling offerings so have now lost one of the three types of pre-amps.

Can I roll back to the previous firmware v1.46 which did not have this issue or is it your Gateway update that is causing this change?

Kind regards

Mick Lawson

My Code is constantly disconnecting from the Gateway app, any ideas ?????

When I follow the instruction for a factory Reset on my Code 50,

==Hold the AMP button while powering on. Once the screen for the reset process shows on the screen, firmly hold the STORE button to confirm factory reset until the screen shows “CONFIRMED”
===

The Presets then are NOT the factory presets, but what I had put in the AMP preset list, with my modifications.
Not visible change has taken place to the list...

What can cause this?

Probably too much to hope for, but does anyone know what the new "CODE 1" box is that has appeared at the bottom of each preset?

Maybe we are going to get a "CODE 2" soon?

Just kidding, I can't see Marshall doing this again.

Ever since the last firmware update my footcontroller has stopped working. It is so frustrating not being able to use it. Needs fixed ASAP.
