Hi, I just recieved my Code 50 yesterday "bought brand new" and the amp sounded great until i hooked up to my pc this morning and downloaded a featured preset not a communiy preset. I am running usb not bluetooth and its my studio setup. Now all the distortion and gain sounds like the input gain is wide open clipping the signal coming in at all volume levels, and on all distortion and od gain presets. I tried to reset the amp and did a firmware update now its litterally so bad you cant play it. This is certainly a software issue cause the effects and clean tones sound fine. This happened immediatley after i sent the preset usb from the website to the amp from the pc. Also i tried several guitars, usb cables, guitar cables and even my mac. just dont know wether i should send it back or if thiscan be fixed with a firmware patch or something , Thanks

Hello Marshall Support Team,

I consider buying a Marshall Code 25 or 50, but I'm really concerned about the master volume problem with these amps, which has been discussed in length in this forum (see ? ? ? or ? ) [sorry,  seems the URL-links to the topics are deleted, the topics were "code-25---master-volume-issuses", "code-50-master-volume", "code-master-volume-issue" and "master-volume-marshall-code-50", all about the master volume knob, which goes from very low immediately to very loud].
In one of these threads you seem to acknowledge the problem and state, that your R&D team will look into this.

So here are my questions:
Is this problem solved with newer versions of these amps?
Does the problem show up regularly with all amps or does it affect only some devices?
Is there any chance to replace the Master Volume pot by myself  if the problem shows up after some time?

Thx in advance for you reply.
With regards - snoopy

Hallo ich habe das Problem das sich der Footswitch ab und zu wie aufhängt, verdrücke ich mich fängt er an die Banks durchzuzählen und hört nicht mehr auf, oder wechselt auf eine zahl und lässt sich nicht mehr zurückstellen, so das ich wieder zu den Presets komme.

Nur ein Neustart des AMPs hilft das er wieder funktioniert. 

Sprich AMP ausschalten warten bis die Lichter des Footswitches ausgehen, und dann wieder Einschalten. 

Habt ihr solch ein Problem auch schon einmal gehabt oder eine Idee was das sein könnte.

Dr. Google mag mir da leider auch nicht weiter helfen.

Mein AMP Marshall Code 100 Head

Hola, hace unos dias mi CODE 25 dejo de sonar. Lo prendo, las luces se encieinde, se conecta a Gate, suena por escasos segundo y luego deja de sonar. Lo apago, prendo y lo mismo asi sucesivamente. Alguna idea?

Hi There,

I have re downloaded the Marshall Gateway app and once its installed i open it and the following message is displayed....

Context 3D not available: Possible Reason: Wrong render mode or missing device support.

Any ideas Marshall Support????

Hiya, I have the Code 25 Amp and have for the last couple of years. I have recently updated my phone to an Iphone 12 pro.  

The Gateway App has installed on my phone. My setting are saying the Code 25 is connected via bluetooth, but the Code 25 and the Gateway App are not connecting. 

I have removed the Gateway App from my phone and re-installed it as advised and have re-connected the Bluetooth from the phone to the Amp once again as advised. 

I try to scan for the amp but it will not connect via the bluetooth.

Can you please help with a solution. 

Thank you. 

Hi There,

I have just bought a CODE 25 amp and i am having trouble pairint it with the Gateway app.

I have done all the suggested processes, reboot, re install etc etc...

It was working yesterday afternoon, then in the evening it just will not connect?

The amp connects to th iphone 7 plus, finds the amp in the menu but wont connect, just keeps saying Connection Rejected!

So frustrating, please can you help?

Cheers DC

I heard a sizzle type of sound one day. I didn't think that was a good thing so I turned the amp off.  The next day I began to play and once it got warmed up, sound stopped coming from the speaker. I can shut it off, let it cool down and it will play once again for a few minutes and then it stops again. I have owned the amp for a couple of years and never had this problem before. Is this a common problem? Suggestions?

I have had a chance to spend a few days with the Marshall code 25 and I would like to share with you a few of my findings. I have played guitar professionally for over 30 years and have had all makes and models of guitars and amps in my time, but in general I would have killed for the equipment available to guitarist today.

This is the point where I look at the Code 25 and think “that looks like fun”. I have a few amps kicking about already, mostly gigging volume amps but I also have a Blackstar ID-Core 40, so this would be in reality what I would compare the Code 25 against.

Firstly my experience with the amp and a look around these forums makes one thing apparent. This amp is well named because it is a bit of an enigma.Out of the box I would consider the amplifier not fit for purpose this is really down to a few reasons.

Firstly, some of the presets are just absolutely terrible, I mean some of the worst patches I’ve ever heard on anything, “Small combo” and the “Brit” overdrive amps for instance are shockingly bad. You can make the excuse that all amp and effects units come with bad presets. However this is usually down to strange or weird effects to give bizarre sounds to show off effects but that nobody would ever use in a musical context. However some patches (such as Small Combo) are just basic amp modelling with no effects and are still absolutely terrible. Maybe these sound better on the 50 or 100, but if that’s the case remove them from the 25 it just gives a bad impression.

Secondly, the amp is stupidly loud. I don’t know if this is a marketing decision, but Marshall should look at its target demographic. This thing is a small bedroom practice amp, maybe at a push for some very small live situations, but that is it. Why make the thing so loud? If you need to use this amp near anything over half volume you have bought the wrong amp it’s as simple as that.

Thirdly, some of the modelling is not all it could be with digital artefacts (in the low end in particular), and a fizzy noise gate that for some reason is on patches where there is absolutely no need to have it as the patch is pretty quiet. Once again this is not a professional gigging or recording product and it should be judgged accordingly.

The last bad point I would say against this amp is the tuner, both onboard and on the app are two of the least responsive and wildly inaccurate tuners I have ever seen. Really not even close to tune! Put this down to another marketing tick box.

OK, now the good points.

It seems pretty well made and solid for what it is.

I like the size and weight, ideal for a bedroom practice amp.

I like the complete range of controls on the amp, and how you can do everything on the amp that you can do on the app, and it’s easy to do. Great user interface design work.

I like the Bluetooth features and the app. I know people have had problems with Bluetooth, but both my IOS and Android phones connected right away and are stable. I can stream music no problem from outside the house or in other rooms with no issues.

I like having 100 presets to store all the patches I could want (My Blackstar only had 6, and you can only have 1 for each model).

The headphone socket sounds OK, but if I wanted that as a primary feature I would have just bought headphone amp with effects.

I don’t use the recording over USB feature. If I did I wouldn’t expect something this cheap to be amazing. Once again if you want this you probably have bought the wrong product, and are in the wrong price bracket.

I like the cost, its amazing what it does for the money.

I like the sounds, now that I’ve got rid of the awful ones.

It looks pretty cool.

It’s a Marshall.

To make this amp useable, I basically had to do the following:

1. Delete all those terrible patches that are just filler and basically just give the user a bad experience. After doing this I was left with around 20 good sounding patches and 20 OK patches, the other 60 I replaced with a patch called “Blank” (which I have put up on this site). That way every patch sound good to me.
2. I turned the Mater volume up to ¼ (around 9 o’clock)  and went through the remaining patches adjusting the patch volume of each to make it a sensible volume for bedroom levels. This ranged from around 0.3 to 5 for most patches depending on the patch. This means that you have more control over the master volume and can change patches without is suddenly blowing you head off. There is still plent of volume in the amp after doing this. OK I admit if I want to use headphones I have to turn the master up around half way, but that’s no big deal. Likewise as I said I don’t use the USB for recording, but I assume I would have to turn up the volume for that too. I don’t see that as a problem either for a product in this price range.

Overall I like the amp and doing just these 2 thing make it much more of a pleasure to use. The volume level are more what they should be for a product of this type and I don’t ever hear any of the awful patches (there are plenty of good ones).

Maybe other people can share their first experiences or tips with the Code 25?

Trying to connect the gateway to my new code 50...I can get the bluetoth to connect but when I try to connect to the gateway it says connection rejected?

Hi, so there's a high pitch whining sound coming from my amp both with and without the guitar plugged in, I believe it started around when I first tried the in-built bluetooth feature and think this is the reason for my troubles. The whine starts at 10% on the master volume knob and progressively gets louder as you crank it up

When I tick the 'share audio' button on  my phone, the whining stops, and is replaced by a very managable amount of noise. 

I've already done a factory reset to try and disable bluetooth but the whine is unchanged and bluetooth is still on. I've also tried disabling all bluetooth devices nearby, shutting off my pc, taking away my phones and switching wall sockets (although I haven't tried outside my room yet).

Is there any way to disable bluetooth on the CODE 50? Or maybe I can take it apart and remove the transmitter myself.

Here's a demonstration of me turning on the amp and moving the mic closer (Master volume at 100%)

I have a 25 amp code and I have been trying to pair of with my fire tablet. The tablet recognises it but won't connect. 

I have no problems connecting it to my iPhone which I normally use but the tablet would handy so my 10 year old son could use it when I'm at work. 

Can any one help?

Bonjour,

J'ai un ampli CODE 50 et je viens d'acheter un footswitch "basique" 2 caneaux (eagletone FS202) avec Commutation verrouillée (loquet) pour la sélection de canal ou d'effet.

Le bouton n ° 1 permet de passer d'un PRESET à l'autre dans l'ordre décroissant uniquement.

Le bouton n ° 2 ne produit aucun effet.

Comment attribuer une fonction à chaque bouton de mon Footswitch? Cela peut-il se faire sur le CODE 50? Est-ce directement sur le Footswitch sachant que le mien n'a pas de réglage apparent?

Dois-je acheter le Footswitch Marshall?

---------------------------  Quelques jours plus tard ... 

J'ai finalement acheté le Footswitch Marshall !

Merci à tous ceux qui ont consacré un peu de temps à répondre

I noticed my Marshall Code  25 makes a hissing noise when I play through any of the clean amp models. This hissing noise is clearly audible when I play a note on the low E string. It reminds me of an old cassette tape. This is especially apparent with the cab emulation switched off. On the higher strings there is no problem. Is this normal? The hiss doesn't go away with the noise gate turned on.  I have this problem with both firmware versions 1.44 and 1.45. 

I recently purchased a Marshall Code 25. Today I decided to update the firmware.  Originally it had version 1.45 on it, but after the update it now has version 1.44. I can't find version 1.45 on the Marshall website. How can I install the latest firmware, which is 1.45?

Is it possible to combine Code 100w with MG412AG extension cabinet and have all 6 speakers work?

Bonjour,

Pour jouer Seven Nation Army, il y a plusieurs réglages différents. Je ne maitrise pas encore le son du code 50 et je suis à la recherche des différents réglages de l'ampli.

Merci
