My code 100 started making a noise recently. It is a high frequency hum. It is particularly loud with spicific presents, but it there with everything. I updated the firmware and that didn't fix it. When I factory reset it, it goes away until I turn it off and on again. Also, if I turn on the amp while holding down the "amp" button, and don't conferm the reset it also goes away (until I restart it.) Thoughts?

Went through as instructed. Bluetooth seeings screen on phone set at 'scan for devices'. Pressed both 'rev' and 'power' buttons. Amp displays 'Bluetooth pairing enabled' followed by a 10 digit pairing code. But my phone simply won't find the amp. The phone is a Sony ZX1 with latest Oreo software.

Tried the same process with my wife's handset which is a Samsung galaxy 5.

No amp is found on that device either with the same process. 

Not sure what's left to try  

Any advice 

When I hold down footswitch 1 to access the turning on/off of my compressor it doesn`t work anymore. It does this in all banks and patches yet worked perfectly previously. I`ve only had it a week so is it faulty or can I resolve this please?

hello,

i have the above titled amp which has lost power and will not come back on.  while i haven't thoroughly diagnosed the amp i wonder if it does need a transformer replacement which would be best to replace its Drake 789-66/5?  Thanks to anyone who can help,

Hi, I have a Marshall Code 50, purchased in the US in 2016. I moved to Germany by the Dec. of 2017 and for whatever reason it stopped working. The PSU was replaced and the latest firmware at that time installed (repair done at Musik Meyer).

It worked fine until today, when the bluetooth is not connecting anymore. Any of my devices with bluetooth can detect the amp. I already tried installing the latest firmware, reseting to factory settings, "last resort" process on troubleshooting guide.

How can I get this issue fixed?

Hi,

I have to replace the power valves on my 2525C jubilee.
And I do not know if there is a bias setting to do.

Is the 2525C a cathode amp bias?
A class A?

Thank you in advance for your answer.

last i can see is 21 july.  

Hello, I recently purchased a Marshall Code 25 amp, and i'm not sure if the crackling sound was there from the start since it's barely audiable and when i play i can't really notice it, but when the amp is on and the guitar is not plugged on( or it is plugged in) there's a weird crackling sound that occurs every 6-7 seconds

Here's a video showing the issue https://www.youtube.com/watch?v=DWFHlhBU1R8

Any idea guys? I tried switching the power cable and the power socket as well same issue. 

I have several feature pre-sets saved in My Library (Laptop using Google Chrome browser). How do I get them into my Code 50 or the Gateway app?

Hej i have a Marshall Silver Jubilee, the serial no. Is 06278. Can you tell me witch year it's from.

Best regards

Does anybody else have a noise issue after an update on the firmware?

My Marshall code 50 was dead quiet until I have made an update on the firmware. 

on Line at the marshall website ?

Or do I have to mail in the warranty card old school style ?

Due to an older brother, I began really listening to The Marshall Sound as early as 1972. Then he gave me my first guitar in 1976. I wouldn't put it down and learned open chords, power chords, scales, etc.  Of course, seeing and hearing live from shows from KISS in 1977, and Ozzy with Randy Rhoades, through Def Leppard and many many others, but it was AC/DC's Back In Black, Hells Bells that did it for me. I found a full, used stack around 1984, and I was lucky the lady dealt with me, gave me a break and let me pay it out. Since I have owned different amps (Fender Vibroverb Custom with the Diaz mods, Peavey, etc), but I have also owned the 150W AVT, and even the cheaper, solid state MDFX 100W. These never came close to my first. 

I JUST purchased a DSL100HR, I guess the new, revamped model. I love all the features, however, the footswitch reminds me of the MDFX or HDFX that has two buttons only on it. When I went to Marshall's main site, I found that the MIDI port is for a fantastic footswitch, which would allow me to do many, many things, without having to stop and turn knobs in the middle of a song.  

Where can I purchase one of these and for how much?  I live in Texas, in the United States.  I had to sell the no longer in production Vibroverb Custom with the Cesar Diaz mods, which was my Pride and Joy (I met Stevie Ray Vaughan after a show on October 8, 1983, in South Dallas, and we began talking about Hendrix, he literally had to be pulled from me). 

Please let me know where, how much, and how I can get one of these, please.

I can play music through Bluetooth on my Code when using iTunes on my phone, but get nothing when using the playback tab in the Gateway app. Where am I going wrong, folks? 

Just got my CODE 100 2x12 and I can't seem to sync up the presets I've chosen on my PC, I'm using my Android device and sometimes they're there, sometimes incomplete, sometimes reverts back to factory. The android app seems faulty. If I hook the amp up to my PC will it always remember the library presets? I don't want to rely on PC or Android to remember my hard work.
