Why can't I register my CODE 50 online? On the physical card it gives the website, marshallusa.com/warranty but that link does not work. In the forum you addressed that by telling us to go back to the dealer. WTF is up with that? Having to fill out that tiny card and mail it is BS. Unacceptable.

Amp is a little over a year old was fine then past few weeks after warmup the volume would dump. All cables, inputs were checked and new JJ tubes put in which seemed like it fixed the issue However when I engaged the Tone Shift button the volume dumped again and when manipulating this button it caused the amp to crackle and seemed to be shorting out the power which intern was dumping the volume.. My tech replaced the Tone Shift curcuit but still when pushing the button in it causes the same issue, we are at a lost..and frustrated...Any Comments or Suggestions greatly appreciated

Dear,

I have a new Marshall DSL1CR and it make a popping noise when changing channels from the Ultra gain to Classic gain while playing.

If I mute the guitar, or changing channels from the Classic gain to Ultra gain or using the emulated out there is no pop.

There is same noise when switching off it.

Is it normal or somethings wrong with my combo?

Thanks & best regards.

I need a new circuit board for my Marshall 20/40 combo amp. I turn the amp on and it will play for a little while and then all sound ceases until I turn it back on. I've change out tubes to no avail and I broke out my old amp mod equipment and tested circuits. That's the only piece I am unfamiliar with so I'm thinking that's the issue. My vendor tells me they can't order it because the amp is discontinued. Where can I order one so I can fix my amp?

Is anybody else having problems 

context 3D not available ! Possible reasons : wrong rendermode or missing device support 

Is there any option to change volume with the PEDL 90008 ?

I know that it is possible to change volume by editing different presets. 

But I want to know if there is a way to change the volume with other methods.

Would be great if there were an FX  to change volume in switch mode.

The manual that came with the head says use output 3 when using a single 8 ohm cab. 

The online manual on the Marshall website says to  use output 2 when using a single 8 ohm cab.

I  have plugged a single cab into these both  at different times and output 2 seems to have more volume and treble than output 3

I am slightly confused and annoyed as shouldn’t  either 8 ohm output sound the same irregardless of which one I plug my single 8 ohm cab into?

I would appreciate some clarification so that I can use the correct 8 ohm output for my speaker cab!

Update to my original post as I  have an additional question related to rear speaker outputs.

The third output speaker socket and the revised manual show this as output for 2x16 ohm. (Mine has the modified sticker attached)

Does this mean:

a: that you can plug two 16 ohms speaker cabs which have been set up in parallel into output socket 3 and the power amp sees a total of 8 ohms? .

b: output socket 3 already internally wired in parallel with socket 2 and such you plug one 16 ohm cab into socket 3 and one 16 ohm cab into socket 2, for a total of 8 ohm impedance?

c: Not sure what else could be possible?

Could you please confirm which is the correct approach? Thanks, Ross

Has anyone any settings for Rory Gallagher or Derek Trucks Slide?

Good day. Yesterday I bought Marshall Mode EQ headphones and ran into a problem.
Smartphone ASUS Zenfone 4 max, Android 8.1.0. When the headphone cable is shaken while listening to music, the volume on the smartphone spontaneously decreases. What can you advise?

Hello,

I purchased a code100H head and cab last year and I love it very very much.  (I am an enthusiast and use it to play music via PC)

I would like to upgrade and buy a second cab in order to make a "tower", for example this 8ohm cab https://www.thomann.de/ro/marshall_mg412bg.htm

Question

Can I connect both cabs to the same amp considering the code 100Head has a single 8ohm output?

Is there a safe "trick";

do I need to purchase a second amp;

what are my options?

Thank you kindly,

Adrian

I have seen a couple of questions pertaining to usb connection from Code USB to iphone or ipad for recording in garageband, etc. 

The answer given by Marshall reps was the same for both and that something about difference in usb 2 and lightning cable.

My Question is: Will an iphone camera connection kit correct that issue? It has the female end input of USB on it.

I use it to connect my Arturia Keylab Essential to my ios apps and it works fine. 

I’d hate to damage my Code 50 though so I came here.

Hoping for a speedy response.

Je n'arrive plus a faire reconnaître mon téléphone dans l'appli gateway Marshall

Le téléphone se connecte via bluetooth mais l'appli ne me donne pas accès au réglage / pas de connection

Je ne plus piloter mon ampli avec le téléphone alors que cela fonctionnait parfaitement auparavant.

J'ai fait une mise a jour de l ampli par USB 

Quelqu'un rencontré le même problème ?

Merci pour votre réponse.

Éric.

I just got a Code 4 button footswitch for my Code50 amp but it does not do anything. No lights, nothing.  Do I need to do anything to the amp to get it going?

Hello everyone!
I have a CODE100H + CODE412.
I love this amp, but I have some problems with the distortion pedal (MAXON SD9): when I turn on the pedal I hear a very high-pitched rustle (With the old amplifier the distorted sound was better). The pre-amp in the Code is JCM800 ("clean" and without any effect) ... does the same thing happen to someone?

I was having difficulty syncing my gateway app to my Marshall.com to add downloaded presets to my library. On the forums Marshal suggested doing a factory reset by holding the amp button down while restarting the amp. 
I did that. Now when I try to Bluetooth connect the gateway app and the amp I get this an error that says "connection rejected. You may only control amps you are already connected to for audio output". 
I have restarted the amp and phone but I keep getting the same error message. 

please advise on both this current problem as well as how to sync my gateway so that the downloaded presets get added to my gateway library. 

I would like to know if someone is using code 25 for small performances with a band. Using i.e the headphone as line out to a mixer.

How are the four Celestion G12M-25 (25W, 16Ω) speakers wired ― series or parallel ― inside the 1960AX and 1960BX extension speaker cabinets?

Hi,

I have a Nokia 6.1 running latest Android 9. Downloaded and installed app on sd card and it does not even start up, just a black screen.

Is the app not compatible with this phone and anroid version?
