Our 11yr old son,  Marshall,  has an AVT150h head and 4x12 ... is there a refurbishment/customisation service available through the design store for used units? 

Is there a user manual for a PEDL-91003 2-button footswitch?

Hola

I just updated the firmware and gateway. The app stops on android when you are going to change a parameter within the preset that is on the screen.

It didn´t happen before. Could you fix it?

Thanks so much

Hello, I want to change the knobs on my JTM ST20C because the original are not  functional enough for me.
I want to have the old style knobs with a silver hat....wich ones will fit?

Mvg,

Toon.

I bought my amp in 2017 I think it was the first series, it was totally new thing on the market. It went wrong about a mounth ago. I brought it to a dedicated engineer, who knew what could be the problem,  He told that it is a common mistake with these amps (I don't know the exact english name of it) , where the elctricity arrives to the amp was too sensitive. Marshall changed it later. There is no part for the original, the new part is not good for the old amp, so there is no way to repair it. Is it true?  

Dear Marshall team:

I use the Code 25 amplifier, with the Gateway app and the Code series footswitch. The firmware is updated with the latest version available.

For a long time I have been noticing certain problems, mainly:

-The preset settings are changed on their own (sometimes the volume, other times the gain...) They are usually changed to the settings on the control knobs. I load the preset again, and after a while some of the settings are changed again.

-Another problem is that after using a preset for a while, when changing to another it does not change (it stays blocked). It does not respond either by using the pedal or by changing the preset from the app I have to turn off the amp. At first I thought it would be a Bluetooth problem, since I was using the Gateway application, with an iPhone. But now I'm using it with an Android phone and I continue to have the same problems.

Waiting for your comments, receive a cordial greeting.

Eduardo,

My code 50 amp display screen just flashes rapidly when I plug it in and turn it on with no display the amp does not work help me

Can I put KT 66s or swap any tubes in my JTM Marshall studio

Where can I get more information about the DI Output? The manual says that it may contain a loudspeaker emulation, but I want to use my IRs. How do I bypass this loudspeaker emulation? Also, do I need to connect the amp to a loudspeaker using the DI Out?

Thanks,

Matt

I commented on a post from May in which the author noted unusable AMP models and problems with the effects, Distortion and Overdrive.  The author noted this followed most recent firmware update.  I too have come to realize excessive noise with my Code 25  when using AMP models other than clean. And engaging the Distortion/ Overdrive effects models is notably noisy  with a background ticking or pulsing.  I normally use Clean amp models., so had not associated with update to 1.47, but don't recall this from previous version. 
Anyone else have this issue?  Any action to address?  Any chance a Factory reset might clear this up?  Thank you

I have a Marshal Emberton 2 speaker. Is it normal that when turning on and off the speaker(the electric sound it makes) it sounded low volume? something like 20% ? My music is ok tho my concern here is the when turning on and off the sound it makes is a little bit low in volume...

Hi, I just received these today and the app refuses to find them. I am unable to perform and kind of hardware/factory reset and as someone in the software department has decided that the firmware can only be updated through the app this kind of begs the question - if I need to update the firmware to potentially get the app to find them then how would anyone reasonably be expected to do this?

Also how do I do the reset? I have tried the holding in of the M button and control knob for 7 seconds and nothing happens. Is this still the current method? If not is there another one?

Is it possible to connect more than 1 device to a Code 100H amp? Either separately (one at a time) or simultaneously?

Thanks.

After multiple fuse replacements. The dreaded turn the amp on and it started smoking. I was absolutely and critically aware of fuse values and took every opportunity to make triple sure the exact value and replacement was done surgically and with exacting integrity with regards to fuse ratings values and type. ie slow burn and so on... I am in Florida and there's no actual service center within 60 to 80 miles of my location. Although many attempts to find one that actually does warranty work is a joke. The only actual people that I could find that said ship it to us are in California and the cost is ridiculous as I bought this brand new from American music supply who was of no help until Marshall's warranty runs out after 5 years. Then they'd be able to help me with their golden warranty after the manufacturer warranty expires. What good is that? So I wait 5 years to get something done? I have an 1100 dollar brand new looking paper weight. Needless to say I am frustrated beyond the scope of sanity as I build custom guitars and rely quite heavily on this as a sonic litmus tester. I purchased the Yamaha thr2 30 watt to try and use in the mean time but it doesn't give me an authentic profile sonically. So out another 600$ .4 of the big black caps have sprayed some type of black chared chaff directionally from pinholes that are visible from removing the head from the cab. This is insane to me that a now year and a half old paper weight now adorns my studio and I can't even find support after logging in to my profile through Marshall. Is this the way marshall is now? What can I do to get in touch with someone who can actually help me without me ponying up a considerable chunk of change for a new amp that is handled with kit gloves. Sorry for the novel and the negativity. I just feel abandoned and taken to the cleaners. If I can't get some support from marshall I'll be forced to do a YouTube video about this experience with factual references that show how insane this truly is. Please help Justin

Hi,
when I connect CODE 25 to Centos 9 I get a mono device, qjackctl shows the amp as  "CODE mono - capture_mono";
when I connect to Windows I get a stereo device (as expected).

Is there a way to make it work as a stereo device ?
Thanks in advance.

The Gateway app on my Android phone has been repeatedly losing connetion to my CODE head in recent months, and attempts to manually reconnect have usually failed. This unreliability is completely unworkable for gigging, so today I have tried to solve the problem through a thorough update and reset ... but now I can't get the connection to work at all. I deleted the Gateway app from my phone, unpaired the phone from the head (by "forgetting" the Bluetooth pairing), and have installed all pending firmware updates. When doing those installations, I noticed that several related to improving Bluetooth operation, so I was hopeful this would solve my problems. So I've gone ahead and carried out the "First connection" instructions on the website, but these instructions have failed at a very early stage. After I press Rev and Power and get the blue flashing light, when I attempt to "Pair new device" from my phone, I get the message "No nearby Bluetooth devices were found". This connectivity problem is definitely at the Marshall end, because I have checked that my phone is able to connect with other Bluetooth devices and it is doing so fine, so the fault is not with the Bluetooth operation of my phone. It seems like there have been some known Bluetooth connectivity problems that you've tried to fix during recent firmware updates, so is this something you can advise me about and give me a fix for? I hope so - there's not much point in you having a really good product if it's unusable in practice.

Hi Everyone, I have just bought a code 100 amp. Everything seems to be working yet I have no sound.  I have updated firmware, factory reset, checked fuses and wiring all seems fine. I can hear music from my laptop very faintly but if I turn up the master swtich it disappears. The headphone jack also does nothing.

Any advice much appreciated. 

Compré el Marshall 50 y por alguna razón se quedo mudo cuando está en uso.

La pantalla todavía está encendida, todas las funciones funcionan, pero el sonido no sale.

Para volver a la normalidad, es necesario reiniciar el dispositivo, pero el problema se repite poco después.

Si lo uso con el teléfono el problema no ocurre, si conecto los auriculares se escucha, el problema desaparece como si se hubiera reiniciado, pero pronto vuelve a ocurrir.

Me gustaría saber cómo proceder.

Dear team, when I plug my headphones in the emulated out f my DSL5 CR I get a constant background noise/hum and the sound appear somehow distant. I use a Marshall Monitor headphone that work perefctly on other devices. Is there a way to fix this? Is this a nrmal feature?

Thanks for your kind help

I just did the latest firmware update on my Marshall Code 50. My headphones suddenly do not work when I plugged them into the jack. They worked prior to the update. I tested them on another amp and they worked fine. Has this been a firmware problem? Any possible solutions? Thanks.
