Hello, WiseOnes...While powering up my JVM 410c with various effect pedals (some are daisy chained/9v, one is powered by an 18v adapter), while the amp is in standby mode, I get this squeal, like a howl from hell, that sounds like my amp is being consumed from the inside out...(okay, I exaggerated a little...) but it sounds horrible. After a while, it recedes, then goes away...at first I thought it was like some type of random radio/tv signal being picked up somehow, but I don't know. I'm probably doing something stupid with the pedals, right? HELP!!! Thanks, you guys!

No automatic bluetooth connection after firmware update.

Please solve this problem.

Or support firmware rollback!

Does the Code 50 have looping capabilities? If so, how do you access it?

How can I check which version of firmware is loaded on my Code 25 bought in March 2018?

Hallo, 

I have a Marshall TSL100 from 1998. I have watch a video on youtube recently where a guy swaps his main board wich for TSL original is issue 6 I think and puts on issue 20. So my question is can I maybe buy such board direct from the factory in Milton Keynes UK and what will cost if it’s possible at all?

How to best use external pedal (Blaskstar HT Metal distortion pedal) with Code 50 amp? 

Hello from Ukraine, Marshall team!

Can you add in the next update, if it will, fuzz the pedal or create a preset with fuzz sound.
Thank you and apologize for my English.

Using the the Fx Loop with my Boss GT-100 via the four cable method, can I put the Overdrive, Comp, Wah, etc., effects before the Code 100 preamp and the Delay, Reverb, Chorus, etc., effects after the preamp and before the power amp and the cabinet? In affirmative case, these functions (preamp, power amp and cabinet) remain available?

Hello!  I have a Marshall DSL40c, which I absolutely love.  I swapped the speaker out for a Celestion Vintage 30 (16 ohm) a little over a year ago, and it sounds great.  However, I recently got a lower wattage tube amp (Vox AC4TV) and have been running it through the DSL40c (basically using the DSL as a speaker cab, with the power chord disconnected). 

So here's the problem:  After 2 days of using this configuration, the DSL has started making a sound when I play the vox through its speaker.  The best way I can describe the sound is that it is like a tabmourine, like those little metal disks jingling together.  It does this on certain notes, like the open low E string, or a C chord, but not on other notes like a B chord (i.e. 1 fret away).

When I run the the Vox alone through its internal speaker - no issues at all.  When I run the DSL amp section alone through it's vintage 30, no tambourine sounds, although it seems that the green clean channel is lower volume than it used to be (the other 3 channels seem to me the same volume as normal).  There is also some instability in the volume (goes in and out, but in a sublte way).  There is some clicking and popping when I first fire it up, but this stops after it has been on for a while so not sure if this is normal or not.

I have been looking up reasons why amps may rattle, but everything I am finding describes issues with the tubes that are being played through - my issue seems to be a bit different, since the rattling (tambourine jingle) sound I am hearing seems to be coming from the Marshall when I am not using its tubes (playing through the Vox as a head).

Is it possible that a tube has gone bad in the Marshall, and when I play the Vox through the Marshall's speaker, the vibration is rattling the broken tube and making this tambourine sound?  Would a reduction in the volume of the green clean channel imply it is a preamp tube vs power amp tube (since the other channels are unaffected?)

Thanks for any help you can offer.  I don't mind taking it in to a tech, but I have read a lot of posts of people who took their amps to techs and had tubes changed, etc. and the problem persisted.  I want to have a pretty good idea of the problem before I start investing in having it fixed.

Thanks!

Hello!

I just bought a Code 100 head and a cabinet.  I want to use the head in a smaller room to learn more about it, using headphones or a MG15CFR,. Can I plug in the head to the input?  As the cabinet is rather heavy its really hard to move it to another place than my "studio".

After the sparking and smoke, it fried some wire's inside and fried a circuit board!!! Should  I just start over with the new Code!!! I love my old head, but cost is a consideration! Thanks for your outlook !!!

Hello, there. First of all sorry for my bad english.

I got two CODE 25, and it cannot be automatically paired with my phone again if it was rebooted.

When it is turned on, the blue light does just keep off and never get reconnection process.

Both of these got this issue after firmware update, and factory reset and troble shooting guide does not help anything.

I tried every ways so many times but it was useless.

There are many users suffering from this issue just like me... it is really annoying even this amp is really good.

Please leave an advice. thank you.

I've been enjoying my Marshall Stanmore Bluetooth Speaker for 5 years and it has suddenly stopped working properly a few weeks ago. When turned on, the red power light is coming on but there is no sound coming out, either when pairing via the Bluetooth connection or the Input source using the audio cable. I can hear a very low buzz sound which stay at the same volume level (even when turning the volume up). The speaker connects to Bluetooth but I can't get no sound out of it. Have tried with my Mackbook Pro and iPhone. I also have a Marshall Acton speaker which works perfectly. Any idea what's wrong with the Stanmore? Thanks.

Greetings from Vienna!

I have this amp since 4 years and the problem is, that the volume control knob is way too sensitive in the low level. Even if I turn it a 1/2 mm up the volume jumps from too weak too much too loud.

As I am using this amp in the studio for rehearsing and use a mic , it is allways a problem of volume. The others go directly into the PA not using the loudspeaker. As I cannot play mine at low volume it is too loud and disturbing the others.

Please advice

best regards

Gerhard

     I picked up a Code 50 last week so far I love it and the possibilities it offers.  Only issue I have had is when the Bluetooth is connected to my phone (Samsung Galaxy S7 Edge) if I get the phone too close to the amp I get a weird digital rattling sound coming from the amp.  I have not tried to see if same issue happens with my Android tablet though.  Has anyone one else had this problem or know the cause?

Where please Marshall Gateway for Android 4.2.2 ???

Hi,

When I connect Phone via bluetooth, I can not see a presets, only "tab to sync" when I tab  it is shows this one and one or two more, but the rest is still tab to sync. Next connecting and all presets list is tab to sync again. Code do not want to synchronized with gateway. Do you have any idea how to change that?
