The Gain and Mid knobs on my Code 25 are unable to reach 0 or 10 despite being turned all the way down and up; the gain's range is 3.7-8.1 and the mids are 1.9-6.1. Resets and reinstalling firmware have yielded no results.

Have enjoyed code 25 for a few years.  Suddenly the amp has started to drop output.  Happens after a few minutes of playing.  All lights on, no noisy pots or anything.  Just no output.  I can switch it off and back on and output restores.  But after a short time, same thing.  No output, suddenly cuts out.  Nothing.  Anyone seen this?

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!

CODE 50

i have a question is this a legit one that I bought.??

Dear Marshall....

I'm a total fan and player of the Marshall Code Amp. In my opinion the best amp in the world ( The Marshall Code) that is...

This amp has everything I need to gig.. record..  and just jam... in one easy to carry unit..  But... I have a problem... my USB plug on my Marshall Code 100w Head is broken will not plug into my cord because the USB port was damaged by me. The prongs in the head were bent backwards and are broken...

IS THERE ANY WAY I CAN GET THIS AWESOME AMP FIXED... PLEASE 🙏 

THANKS.. Allen Perez

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 have  Marshall Code 100 and it is ususable because the presets keep changing by themselves. Is anyone else facing this issue? 

Why i couldn't can connect my Headphones with my Phone on Bluetooth??

I have the Major IV Headphone andta Phone from Xiaomi M4Pro

Bonjour,

Comment faire pour supprimer un preset de l'appli Marshall Gateway( code25).

Merci

My chassis says PWB980801A and after being told to junk this amp I saw an article that said burnt components definately harm other parts.  The burned parts on my circuit board are 1.) ZD3, 2.)another ZD3, 3.)R111&270J DAEDO, 4.)R112&330J DAEDO, 5.)a blue resistor with 2 black and 2 red rings on it, 6.)desoldered TR10, TR15, TR6 & TR9.  When I lived at 522 Rhea Street in Long Beach, CA  someone I was living with asked me to take my guitar and amp outside and play.  I did but a policeman said he would have me arrested is I didn't go back inside.  I would like to keep this amp but it is kind of loud for the one room where I live.  All the repairmen I've found have refused to fix it.  I told ASCAP about VanHalen and got $5,000.00 and bought this amp in 1984.       

I own a MARSHALL JCM800 LEAD 50W 4210 (1X12", 2 CHANNELS, REVERB), with many years of use, I bought it new about 36-37 years ago!!!, and now the reverberation has started to fail, if I go up the REVERB potentiometer makes a lot of noise and when it goes past 1/4 of a turn feedback appears, I don't know if the problem is electronic, or if the reverberation module has broken, I think it has an ACCUTRONIX or a HAMOND (I haven't disassembled it) Can the module be repaired or does it have to be changed directly? What brand and models is it? Where can I get one? If the same model is no longer manufactured, what would be the equivalent model?

Best regards

Here's an interesting thing. User Tomáš Nekovář, stole my Octafuzz preset and put it up as his own. Even complete with my Youtube link and soundcloud demo.

Seen it all now,

Oh well it was put up to share anyway, so enjoy MY patch everyone.

Why boost pedal doesn't work at Marshall code 50? I have plugged the electric guitar into volume pedal and the volume pedal into guitar input on amp, but haven't had no boost effect! Will volume pedal work? I'd like to boost my solos, anyone faced this problem?

I'm finding it hard to register my brand new Origin50C. Can't find the serial number it's covered by a sticker on the box. No where on the amp itself can I find the serial number

need Metallica tones for "Black" and "Justice" album

I'm restoring a couple Marshall speaker cabinets, maybe from the 90's. Two of the above speakers are not working. 

Thanks,

Hi everyone, 

I bought the new DSP module and plugged it into my Code 25. Everything seemed to be fine,

However, when I turned it on the code went into bootloader mode and said "chk usb". I inserted a cable and my PC saw it saying "connected". Still neither the marshall site not the PC application provide with possibility to update. The site shows no information and the PC app says that the last firmware version is installed and cannot reinstall it. When press reinstall button nothing happens.

I tried Mac, MS Edge and other browsers, nothing works

Any ideas?  

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!

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.
