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?

hi, i just got a code 50 and i need it to record with. i want to use the headphone as a line out into my interface (roland quad-capture). my question is should i use a UNbalanced jack into the interface or can i use the balanced (stereo).

because right now using a 1/8" jack out of the amp and a 1/8 to 1/4" adaptor sounds really bad out of the monitors. can someone please help me with this.

thanks

how can i download the owners manual for the cade 50

I was just wondering if and when I need to changes the tubes in my 2525 mini silver jubilee head can i just put the same type tubes in it or does it need to be biased?

Hi all! It's a good day to be a Marshall owner!!
I have 2 questions , I have been using my model 4120 through a cheaper model Marshall Cab a G412C and I have to say all this time I thought it was a 1960 B. Well I bought a 1960 B and now notice the difference, in my defese the cabs look identical and the G412 was bought used and the Marshall Logo on front and tab in the lower left corner was never there when I bought it. I do notice that the 1960 is 300 watt at 16 and the G412 is 120 at 8 can I run both cabs through my model 4120 Dual Reverb head and also what is the high low switch on the back of the 4120?
Thanks yall and I appreciate your "input" ( see what I did there? )

I have a vintage Marshall amp that I love. Is it possible to use a headphone set with this amp? If so, how! 

Thanks

Good morning! I bought a Marshall 2555X Silver Jubilee amplifiers! and a Marshall 2551BV Silver Jubilee speaker cabinet. I have tried to register the speaker cabinet! but it does not work. It might just be possible to register amplifiers?

Sincerely, Mikael in Sweden.

Tried to update my firmware and tried three cables. None are even recognizing the amp on multiple computers. Tried to reset the settings on the amp and nothing helped. It seems as if the USB port is not working at all.

I have a 70's JCM 50 W lead I want to replace the tubes - 2 x 6550 and 3 x 12 ax7 ecc83, original GE tubes are in the amp. I am told I need to repalce the power tubes due to the 3 amp fuse keeps blowing. 

I am able to connect my phone to the amp via bluetooth, but for the most part am not able to sync the presets in the gateway app to the amp.  On occasion it will do it, but most often not.  The tuner and playback work fine.

i dont know the code

Can you factory rest all the Code 50 pre-sets, and if so, how?

Hello,

I obtained a Marshall Haze 40c and was wondering if there were any current-production amp footswitches that mimicked the 4-button footswitch for the amp that is now discontinued? I have seen some on reverb, but they are a bit pricey when shipping is added to the mix. 

Also, im a bit tech-savvy and wouldnt mind making my own. I understand what it takes to make a 2-button channel control, but unsure how to wire a 4-button switch. Any schems out there ?

Can the CODE series amps be accessed via laptop? Or is Gateway for iOS and Anroid use only?

I have a 50w Mk2 Lead amp serial number 6232H    

I was curious as to what year it was issued?

I can download and run the firmware updater on my Win 10 laptop - it then asks me to connect my CODE 25 amp. I connect the amp using a USB cable - then I see the message "An error occurred: An error occurred getting the device information from your CODE. Please try switching your amp off, and then switching it back on again."

I switch it off and on - no good. Same problem. I connect the CODE amp before running the firmware utility - same result. So I don't even know what firmware is currently in there. Is this solvable? BTW - the USB cable works, as my Marshall CODE Live Editor has connected to the amp using it.

Thx
