hi the online warranty registration form does not accept my serial number because there are not enough characters in my serial number.

Could a lower V1 tube make the green channel cleaner when I play hard,it sounds like it distorts when I dig in hard almost like a bad speaker but even a new cabinet rattles like that,any suggestion?

Can you explain a simply way how to download presets to Code amp and updates (automaticly?) What those symbols like phone, Code amp with cross over mean? Is really so that Safari does not support downloads, updates? 

My Marshall code 50 suddenly stopped working while playing. I heard a little "click" sound an the power went of on the amp. I did not blow the speaker. Spoke to a friend that suggested that the amplifyer fuse was the problem, as it was nothing wrong with the power outlett i used. Is this a problem i can fix myself? is it likely that the amplifyer fuse are the problem? 

sorry about my english, i´m Norwegian ;) 

I cant change my Profile Image? Ive tried making the image very small like  500kb in size and no go. The pixel dimentions are fine. Its  2356x1940. Are things not working right now or is it a bug?

How  far can you turn this up wihtout blowing it up!? Code 50

Ive got a main  Heavy Metal Tone I use all the time. The volume in the preset is set to  1.8. I have it that low so it doesnt blow my Clean sound away when I click between the two. 

I was playing with a drummer the other day and I had the master volume up to maybe close to half and I was worried I was going to blow the speaker.

So How  far up is safe?

Oh Im using a Code 50.

  Is this the serial number? I believe the last two digits are the manufacturing date?  Can you give some details about this amp based on the serial number. I bought it without a box. I want to register it, I need the exact amp model. eg. "dsl40c -u"

thank you...

Hello folks

I'd like to try a TC Mojo Mojo in to a CODE 25 in clean Settings. Is there anybody with some expirience with pedals in to a CODE?

Thank you for your opinions

Will this model work with my Marshall DSL40c amp?

How long the update process takes? Installation is already 100% but it seems it stuck and amp doesn't restart.

I was using the usb connection to record on Audacity.  The guitar I was using was a Fender Strat with noiseless pups.  I found that the signal stregth was really low and the only way I could get a decent recorded signal was to turn up the master volume to an unbearable level and was close to getting a stern talking to from my better half.  I then tried the same process but used some headphones and this sorted the level issue so it recorded a strong signal.  There was still a bit of crackle on the recording but much improved from the last firmware release.  

I then recorded some acoustic guitar without headphones.  This was a martin DRs1 with a stock fishman pup.  Signal strength was really good and the quality was great.  No hum or hiss or crackle.

Great to hear others experiences.

Hi,
I have a problem when saving Presets from my Marshall Code 25 amp to my phone (Android).
The saved Preset repeats/copies itself about 20 times. Therefore, the app Presets are unusable because I have to scroll down or up 20 duplicates before I reach the next Preset.
There is no way to delete those Presets, and when tapping on one the app freezes.

I already posted this same question in an existing thread in which other people were notifying this same issue, but that post was deleted...
In that post you said you where working in a solution to this, but its have been 5 months since the first report of this problem, so
I'd be grateful if you could fix this as soon as possible and kindly ask you when do you plan to release the Gateway app fixed?

Thanks!

Hi I have purchased a new CODE 50.  I have the latest firmware update but I'm finding the bluetooth is not consistent.  I have it running on the gateway app and then if I move the phone more the 3 feet from the amp the connection is lost.  The same happens if I play spotify through it the range is about the same.  Can this be imporved or do I have a duff model.  My phone is an iphone 5.

Where is the air intake and exhaust on the MG Carbon Fibre series? I own both the MG30CFX and MG50CFX combos ― and because both of these units are completely closed and are fitting with cooling fans ― where (and how) does the air circulate? ― I never hear a fan running when operating the MG30CFX combo. And is the MG100HCFX head fitted with a cooling fan as well?

Are any of the CODE Series amplifiers fitted with cooling fans?

Hi all, I was hoping I could get an owners manual downloaded for my JCM 2553 that I recently acquired. I can't seem to find the old manuals on the marshall site since they updated it. Thanks!

As pointed out in these blogs the Code series locks up during editing and doesn't have an app for Mac users. These issues go back to al least June of this year. When is Marshall going address these issuse other than saying "a solution is coming soon?" I recently purchased a Code 50 but I am not going to hold on to it if Marshall is not going to support it. 

I have a DSL100H, and would like to replace the footswitch with one that has LED's so I can tell what setting I am on with my back to the amp. Can I use a standard externally powered 2 button switch with a TRS cable? 

Are any of the MG Carbon Fibre Series amplifiers fitted with cooling fans? 

So I just got my Code 25 amp and my guitar will show up in a couple days.

Even though my guitar isn't here yet I thought I would have a little bit of fun with it tonight.  One of the features that I really liked about this amp is being able to play music like from your phone through the amp either via Bluetooth or hardwired mini jack.   I did this tonight and to my surprise it sounded horrible! I tweaked the settings on the amp and of course it made no difference because those settings would only affect the guitar input.   I played the music through the music app on my phone then also through the Marshall Gateway app and got the same results. I thought maybe it was because I was doing it via Bluetooth?   But then I hardwired into the amp and it was the exact same issue. I guess there are other ways to listen to music while playing the guitar along with it but I just thought it was a pretty neat feature to have both sound sources coming out of the same speaker but there's no way that's going to happen.   Unless I'm  doing something wrong?
