Hi,
owned a code 25 for a while now but only really started using it during lockdown but have to say I'm really impressed. I'm just using it for living room playing and connected to my DAW as a way of laying down ideas but seriously, it's REALLY good.

For context, I've played guitar for 27 years and working in live music has been my primary source of income (pre lockdown....) for around 17 years. I'm usually a live-sound engineer and tour manager and occasionally fill in the gaps with some guitar-teching. I'm uk-based but have international clients, mostly guitar-based, playing mostly academy sized venues but have done major festivals worldwide and one short stint of an arena tour. The point here is not to blow my whistle, simply to say I've spent a lot of time being exposed to all manner of amps and modelling.

I own a line 6 helix and while the CODE isn't as flexible with regards to I/O, I genuinely feel like it's amp-modelling, especially for crunch, fuzzy or blown out tones, blows the Helix out of the water. Not that I'm as likely to use metal tones or had much cause to tweak them but I've noticed those kind of presets can sound a little thin. Also, higher gain sounds in general could benefit from a graphic EQ somewhere in the modelling chain, as it can be prone to squeak at frequencies usually outside of a regular amps range, presumably because of the full-range nature of the cab.

So, my query is, is there any chance that the CODE range is likely to get any substantial firmware updates or maybe 2nd generation hardware that could bring additional functionality/Pro level durability and a decent footswitch... I'm impressed that you've managed to get that much functionality out of a mono-jack but a few extra switches or even just midi connectivity for use with after market footswitched to access would open the amp right up.

Personally, I'd love to see one capable of more complex I/O routing i.e. the ability to record your dry input to DAW over usb and similarly, route from the DAW to the amp input for re-amping.

Midi I/O and an xlr input with phantom and a decent sounding pre would make it a nice little hub for a solo recording setup.

Anyway, great work Marshall/Softube, really hope you develop the line further.

Ok Marshall we bought your product thinking it would be a good product. With trusted support.  You have failed your customers and your products with no support for the code amps that your customers bought. And now most are stuck with a half working amp that they can't sell or not happy with.  When will you get off your butts and fix the amps with a firmware update? And support the product and the consumers?  Let us know so we can either stick it out or move on to another product.

Hi,

I just bought a Marshall Code 50, it is new but I think it have a problem.

When I move command buttons (Gain, Bass, Middle & Volume) nothing happend.

When I move Trebble button it change Trebble and Volume in the same time.

Also, I saw that settings change without touch buttons when I'm playing guitare.

Could you tell me what I have to do for fixing this issue please ?

I tried to reinstall the firmware but it didn't fixed the issue.

MCU 1.44

Yes, I've read the many questions of the same nature on the forum, and performed all the suggested actions. None of them have been successful.  I've seen many questions similar to mine, and only a few who have been able to make it work... and of those who did, their solutions didn't work for me.

When I connect my amp to my phone's bluetooth, it will pair for audio with no problems.  I can play audio through the amp.  When I open Gateway, there is no "red button" prompting me to connect.  When I tap on the CODE tab in the menu, it says "Not connected" and when I tap on the green "Scan for apps" button, nothing happens.

It will connect to my Samsung tablet with no issues.

Here are the steps I have tried:
Factory reset on the amp.
Unpair  and forget the amp in my phone's bluetooth settings.

Uninstall the app from my phone after clearing the cache and the data.

Update the firmware on the amp (the browser window said I was up to date but I installed the latest firmware anyway.)

What else can I do?  I don't want to return the amp because it sounds great, but not having the amp controls on my phone is a deal breaker.

Having this issue with Code 50 just updated the latest firmware 1.44v

The amp will hangs or store by itself and nothing works after operating for sometime.

Pressing the footswtich or amp buttons nothing works. Have to do a power reset on it.

Any idea what happen to this?

I have a Marshall Code 50 running MCU version 1.44 and Gateway (Android version 1.5.5) on a Samsung Galaxy S9+ running the latest OS. I can bluetooth pair to the amp and play music, but can not connect to the amp to change my presets from the library.  I have reloaded the latest firmware on the amp, deleted and reinstalled the Gateway app, paired and unpaired several times.  Nothing seems to work.  I even grabbed my old Galaxy S7 Edge phone and that Gateway app on it does the same thing.  Does my amp need to be serviced for Bluetooth connectivity?

hi, i got the marshall code 25, it stopped working when i connected it to my laptop right after i updated the firmware, i think there was a problem with the usb cable, now the amp doesn't respond to anything, and no sount comming out of it, i tried to factory reset stiil no responce, when i turn it on, i get on the screen marshall, then B0.6 , M0.0 , D1.1 , then CHK USB, now i was wondering if there is anything i can do to get it to work again just in case if the new usb wont work, please help

thanks

Hi,

I have found a weird thing that may or may not be known with iOS + Bluetooth and the Code 50.

The CODE 50 when playing backing tracks / using it as a Bluetooth speaker is very quiet (So the master is wacked up and the playing guitar is extremely loud). 

and the weirdest thing (which physically makes sense but still it shouldn't do it) is that the Amp is predominatly a Left speaker when playing music through bluetooth as my phone (iPhone 6S) thinks my amp is bluetooth headphones rather than speaker (as the headphone icon pops up on the top right). 

My amp is on the latest firmware update.

Is there any fix for this? There's nothing in the gateway app for audio balencing

Can I use my iPad too update firmware for code 25 .

Hi everyone, so I recently purchased a Marshall Code 25 off of a friend and the amp is perfect for what I need; however, every now and then it starts buzzing out of control. I'll turn it on in the morning to start recording and the buzz is so loud, it almost overpowers my guitar sound! I have tried 3 different guitars, acoustic and electric, bought a high-end Ernie Ball cable and even moved house and the buzz is still there! I was able to fix it in the past by updating ad overwriting the firmware and then leaving it unplugged for a few hours to a day and that solution worked for a long time, but now it's buzzing again and nothing I've tried has made any difference. Another thing, its plugged into the same power strip as my PC and monitor, but the power strip I've switched to is a $50 uninterruptible machine of a power strip that looks like a space ship, to no avail. Also, when I turn my amp on, it makes my PC monitor kind of short-circuit and the picture freezes and fragments for a split second and then goes back to normal. I have tried every possible amp setting, and only setting the noise gate to 80% gets rid of it, which is unusable. I have also tried other power outlets and it only works when it's in a separate part of the house. I should also mention that the sound does go away when I turn the preamp button off on the amp, which again, makes the amp unusable. The house I moved to is also relatively newly made and has had various electricians here to sort out any previous power issues in the past few weeks. I'm at my wit's end and I seriously need some help!

I can't get the phone app and code 100 amp to connect. bluetooth does connect but the app will not show or allow to connect thus make the app unsuable. i have redownload app manty time. reconnected phone many times. amp is up to date firmware. i have had the app working fine and connected in the past.but now no matter how many redownloads, resets and starting fresh i can longer connect with the app to control it. i have been through every setting and all combinations on connecting updatig reseting and nothing seems to work. need help please. thank you.

An annoying problem of Code 50 concerns the sound of low frequencies which are extremely "muddy"
using a Stratocaster's bridge single coils: absolutely no attack & non-existent twang!.

I really like this amplifier and I am sure that with a firmware update this problem can certainly be solved

My current firmware version is 1.44.

Cheers

In a new firmware We need more efects: uni-vibe indispensable,fuzz, efects modulations ,delays,reverb out in stereo please.

Thank you team Marshall

I have tried everything to do the firmware update on my new Code 25.  Its showing v1.11 still.

I have tried Crome, Edge, and downloading the manual windows exe.  I have updated drivers, booted amp in "safe mode" (which identified usb as READY but still wonnect connect in My.Marshall 

Please help!  I love the amp but need to be able to update the firmware

My new Code 50 is bad noisy out of the box. I have tried 3 cables, 2 diffrent Guitars. I have tried a diffrent Outlet. Nothing seems to stop the noise.

I can turn the preset to some that are quiter, but almost all have a noticiable amount of noise and or Buzzing sound.

I have tried Firmware upgrade, IT was the same version, so I reinstalled not luck.

Please help.

We've bought an amp emulator with a firmware, we have spent money believing in Marshall that is a great trademark. Every sellers of amp with emulations inside and a firmware periodically upgrade it. You don't do it. It's time to do it, to increase the number of the amps, the effects, the algoritm need to be more realistic and warming. Come on!

Hello,

I need your help urgently.

from last few days i'm facing a big problem.

after starting my marshall code 50 within 4-5 sec all eq vol gain values changing automatically also after incresing eq gain vol knob its showing max 1.9 values.but its actually in 10 possition also master volume in 0 possition also giving sound.

i tried to reset it and restore all firmware but nothing happen still same result.

so please help me what i have to do.

Thanks you.

I have the Code 25, and just installed the latest updates (1.44) to the firmware. However, I still cannont get the Gateway app to recognize the amp. I am connected via blue tooth as I can play music from my Android phone over the amp, but the controls from the app don't work at all. Again, when I search it does not find an amp. Help? 

Marshall Code 25 Bluetooth not working !!!!

i try to update firmware to 1.44, i try with diferente phones, android/ios/tablet etc.... wont detect nothing.... bluetooth Marshall not appear!... 

Marshall apps is a fucking crazy bad... and support too.....

Need help please. I love my marshall code 25, but without bluetooth i send it back....

Hi I have a CODE 100H head/cab and a CODE 100 combo both with the latest firmware re-installed from Marshall and both have this issue, i.e. the amp very oftenn completely freezes when I save a preset.

Steps to reproduce:

- Modify any patch on the front panel

- Save

- 50% of the times the amp seems to freeze. The preset is saved but you can no longer change preset and there is no sound coming out.

The same happens if you modify a patch from the iOS app via bluetooth and then save it from there.

It's REALLY frustrating and I can't believe I didn't find anything on this forum under the "crash on save" keywords. Seeing it happens on both of my CODE units it much be a software bug, I don't think it has anything to do with my units.

Anyone else has seen this problem?

Thanks!
