After many many many failed attempts to update firmware it finally showed successful on the update page but now the screen permanently shows do not switch off or usb not connected and is unusable, no buttons work ,completely frozen.
I can't figure out how to register my new Marshall Amp on your website???
I have a JMP-1 feeding a Valvestate 8004. Should the Master output be set at +4 or -20 db? Thank you!
Hi Marshall,
I just purchased the DSL20HR and 1912 lead cabinet, which is great. However, there are late nights that I want to play through my headphones.
I read the manual and I read the previous questions on here about headphone use. There's conflicting instructions and support advice between the manual and what I have read here.
Can you please clarify step by step how to safely plug a set of headphones into the emulated output jack of the DSL20HR? The manual says to "NEVER use the DSL20HR...without a speaker load", however, advice here from the Marshall team had stated to unplug the cabinet from the amp, plug in the headphones, and then not to forget to plug the speaker back in when done using the headphones. This is conflicting and I am afraid to try either.
Please help. Thanks

Hi,
I've just received my Code 25 amp today. It sounds good but I cannot pair it with my iPhone
It appears as "Headphones" in the bluetooth settings. When tapping on it, my iPhone says "Pairing failed "Headphones" is not supported".
I've tried with 4 different iPhones (all up-to-date) and got 4 times the same trouble
I've successfully updated the firmware of my amp (MCU 1.47 / BT: V3.2) but it did not fix the issue.
Can someone help ??
Thanks !
When I switch off the amp there is always a crackle in the loudspeaker .
Is that normal or not ?
Thanks
Please answer quick!
My footswitch is not working, just random flashing of different led sticks and numbers - no change from the current preset I'm in.
Is there a way to activate a factory reset of the switch?
Hello, I would like to check my new headphones, are they original or they sold me a fake, please help. Headphones were purchased in Germany
After using Minor III by use wear only one side per time for 2 or 3 days, my phone can't connect to the left side. I decided to unpair then pair again, I can only pair to the phone but can't connect to the in-air and bluetooth system say "An app is needed to use this device". I also uninstall application then install again but can't fix this problem. How should I do?
Thank you,

Is the footswitch for the code discontinued? I try to order it via Thomann but is not even in the list of the available products.
Thanks
After selecting a Preset, and after playing a song when I go back to the Gateway app I see a message saying, "Amp Disconnected, Connection with your CODE amp has been lost. Please check your amp and try to connect again." When I select "OK" it reconnects then I can select a preset. This seems like a new"bug" since the Gateway app has been updated to the current version. My iPhone is on a stand close to my CODE 50 the entire time. (about 1 or 2 feet at most).
Please advise. Thanks!

Need varification on this.
Thanks.
Woburn 1: The Musik plays a view Minutes. Than a soft slow, cracking Sound starts. The cracking Sound gets faster and louder. After a view Seconds you can´t hear anything. No Musik. No Cracking.

I would like to fix the Problem at home, but I need help.
Hello,
I'm going to replace the power tubes with a new kit of 4 matched EL34 and I would like to know what is the BIAS setting recomended by Marshal in terms of how much mV we should adjust on the reading of the Test Pins CON5. I found someware that is 90mV per side, but also other different info (some guy said 76mV after consultation with a techician). Please could uoy kindly advice?
thanks!
I'm looking to purchase a used JCM 800 2203. The model number is M-2010-38-0161-2 RoHS. Is this a legitimate number and what does the RoHS mean?
Hello Marshall
I'm a beginner in guitar, and the code25 and my first amp, so happy !
but the front USB socket on the code25 leaves me with doubts about its solidity...
after 1 year of use my usb socket on code 25 no longer works, by plugging and unplugging so much, the connector is worn.
I of course changed the USB cable, and tried on another PC.
Is there a way to repair the USB connector? or change it?
thanks best regards for your support stef
I have a Marshall DSL40CR. I have checked the amps bias 5 days in a row and every day it's lower than what I have set it to. I was told bias in 40 watt mode should be around 35. When I set it to that on the first day and played...it sounded excellent. I put it in standby and powered off. The next day I turned it on with standby on and waited around 5-10 minutes. When I went to play it sounded really off. So I decided to check the bias and 1 tube was at 30 and the other 33. I reset both to 35.
The next day after that I had to set it yet again because it was 30/31. The next day after that the same thing lol.
Would this be an Amp issue or Tube issue? Once I set the tubes to 35...plays and sounds great the entire time I play. However, if I shut the amp off and come back later the amp bias is always lower.
Hi - just recieved a code 50 footswicth, new and out of the box.. Plugged in and no lights, used a ferw different cables but still no sign of life.. Any advice..?
Hi all,
I bought my Code 100 in Australia, where the voltage is 220 V and the amp only works with 50Hz as indicated on the back of it (unlike many other products that work with both 50/60 Hz).
Now that I have moved to the US, I am not able to use it anymore! I purchased a 110 v to 220 v step up transformer, which is fine, but cannot change the frequency from US's 60Hz to 50Hz to safely turn on the amp!
Frequency converters are like $1000 or so, so definitely don't worth it!
Is it possible to request Marshall's company itself to change the power board or something to make it work normally in the US without transformers, converters, etc.?
Would it be safe to just use the step up tarnsformer and ignore the frequency (Hz) difference?
Really appreciate any suggestions or guidance,
Thank you in advance!
