I have a Marshall Code 50. Not sure what’s happened but when I plug my guitar into it, I get no sound and the presets are now being controlled by the guitar volume knob. If guitar volume is full high, display on the Code quickly scrolls thru presets. If guitar volume is full low, you can individually scroll thru presets by quickly turning volume knob up then quickly back down. No volume from cabinet regardless of preset volume or master volume, only static. Have tried with both electrics I have and both cables, in various configurations with no difference.

Any help is greatly appreciated.

Thanks. Kevin.

is there a way we can look up the serial number and where it would give you the full description of the item, thanks

Trying to update my Code 50 to the new firmware but it says "Not Connected" to the computer. I've tried everything that is on the troubleshooting page, I have an Mac pro and tried with both Crome and Opera. Last time I updated it was not any problems. 

I have following versions on the amp (see this when I'm starting the amp in the bootloader mode)
BL: 0.6
MCU: 1.3
DSP: 1.1

Do you have any more tips on how to update the firmware to the new?

Hi There, 

I just notices this now. Im using a code 25. I have updated the firmware of the amp to 1.44. I also have updated the gateway 1.5.5. May phone connecting to the amp. But the gateway app is not connecting to the amp. Im using a galaxy note 9. 

Any help please. 

Thanks

Hi There,

Im using a Marshall code 25. I know that you can play the dowloadable presets or use the sample temporarily when you plug your amp to your pc or laptop. But is there a way to do this using a mobile phone? 

Kind Regards,

Jericho

I just bought a CODE 100 combo. Bluetooth audio is pairing just fine but the app never finds or connects to my CODE!

I tried everything, i even uninstalled the app rebooted the phone and started from scratch following your guide but still no luck.
Galaxy s9+ up to date CODE firmware 1.44 and gateway app 1.5.5

Fix this please

Hello,

Since updating Code 25 to firmware 1.44, the bootup time is now very slow and can take up to 20 sec before being able to play a sound from the amp.

Wtf ?

Do you experience the same latency?

Any chance of a fix or a possible downgrade ?

Thank you.

I know that turning a "TUBE" amp on without a speaker load on the output will damage the amp.

(the no-load condition will cause the output voltage to increase until the output tubes burn out, which can then lead to other component  damage)

Is this also true for a CODE 100 amp?  Is there a risk of damage to the output section, with turning the unit on without a speaker cab load connected?

Would it be safe to operate the amp with just headphones connected instead of a speaker cab?

Would it be safe to operate the amp without either a speaker cab or headphones connected?

I ask because my computer (which is a desktop) is in a different location in my house than my amp.

Doing firmware updates or testing out patches requires either moving my computer or my amp, both of which are very inconvenient.

It would be much easier if all I had to move was the head.

I’m looking into getting a new IPad and I was curious if I can use GarageBand as my software and record direct from the USB port on my Marshall code 25 to record? Or should I spend the money for a new Mac book or Mac laptop will either of those work?

does anybody know how to pair the apple watch series 4 , it only says the code to pair but i cant pair it . thx i hope it can be pair .

I have just updated my CODE 25's firmware to 1.44. Just after this, it started to make a sound like tapping or heartbeat. I am not sure but it's similar. First, I thought that it's about tap tempo so i turned the amp off and turn on again but it doesn't work. Amp still makes the sound regularly. Before the 1.44 update there was no sound and AMP was working perfect. So if there is a sloution, I really need help.

Thanks.

Hi bought the code100h and love it so far, I already had the mg412 4x12 cab which is 80hms 120w is this ok to run with the head and not cause any problems with my amp?  Or do I need the actual code cab?

Hey you guys ! Still loving my Code, for light rehearsals and mostly direct into my recorder! Any chance of Gateway for Windows PCs? I dig using my Code direct to my computer Studio, and it would be cool to have the Gateway on the big screen as well! Just wondering.

Thanks

I get no guitar through the headphones.  What must I do to get the audio from my guitar to the headphones?  I would like to use this as a line signal to another amp.

I do get audio out from my phone to the headphones when Bluetooth is connected. When Bluetooth is connected, whatever is playing on the phone will be heard through the headphones. So, I know the headphones AND the headphone jack both work. 

Cable plugged in to both computer and Code 50. Display shows 'Ready for Update' - but neither the browser or Desktop Utility will connect.

Rebooted everything and tried from laptop. Same results. What's wrong?

Why can we not update via bluetooth connection rather than USB cable?

Hi There, 

I have been using my Marshall code 25 since last yr and noticed that when the amp is plugged and NOT turned on. There is an electric current at the end of the cable. It only dissapears when I turn on the AMP. The electric current runs until the guitar when its plugged. I have tried the cable on other amps and it was fine. 

Has anyone experiences this? or is this normal? 

Appreciate the response. 

do I need to have a speaker connected to thecode 100 if I am using headphones?

I think I might have tossed out my USB cable by accident! I cannot find any place to order a replacement one, not even on Marshall's web site.

Hey Marshall, you ahve my email, why not tell me how much and where to pay so I can get a replacement and update my Amp!!!!

Brian C.

after correctly updating the CODE AMP and the Gateway, the connection is still wrong, I had hope with the last update but it has not helped me at all.

he version of android that I use is ANDROID 9, with the phone Galaxy J6 + ..... I do not understand where the problem may be.

I would appreciate Marshall's help in correcting this problem, they have already contacted me for a long time but the guidelines were erroneous from the beginning.

Thanks for all.

Can I save downloaded user presets to my footswitch and how???
