Was Playing a gig llast night with my one year old JVM 205H when I went to the clean channel it was muddy/and the gain was all the way up not like my usual sound for that channel.  Any Ideas?  Tube Replacement?  Any advice would be great.

Is there a way to use the code 25 as a cab for something like a micro terror, hotone mini head or any other head? 

I have one JCM 2000 TSL 122

The main supply is set to 230 V 50HZ. I Live in Brazil, here the voltage has an frequency 60Hz. What should I do?

After having played privately for 25 years on a Peavey Rage 158 The Code is overwhelming and I'm loving every minute of it. Really enjoying hearing a preset and having my head fill with songs that fit the sound. Its a brilliant idea and please keep refining it and updating it. 
Question 1: Has there been an actual firmware update yet? the software said my code is up to date out of the box so I just want to confirm my software is installed properly.

Question 2: I would love to get a fixed date on the foot switch if you have one yet. 

Question 3: Is there a master way to get all the preset volumes to the same level or do I have to configure my favourite presets individually in order to get them to the same volume?

Great job to you and the software company.

On the code 50 there is an option to edit the presets but this is not on the 25. Is there still a way to edit presets?

Can the usb be used for anything other than recording?

Where can I download the Code 50 owners manual so I can get more from my amp?

Hi Marshall,

I have recently purchased a Marshall CODE 50 and I want to register the amplifier online and for some reason I cannot find the Serial Number on the back of the Marshall CODE 50.

I can find the Model Number: CODE50 but nothing indicating a Serial Number.

Can you please help.

Hi,

Would you recommend using a high (250-300Ohm nominal) impedance Studio Headphone with Code50?

Or should I go with a low impedance one?

Just love my new Code 50 btw :)

I have a Marshall valvestate 2000 AVT100 and suddenly the fx module stoped. The  amplifier works like always "good" but the fx module is death. What can be the matter??

It doesn't works,

I'm a new owner of JVM410hjs, I just found out that the serial fx loop got problem

I have plugged in an effect chain into the fx loop, I have enabled the fx loop on the front panel,

what my question is that if I haven't plugged in the power supply for the effect chain, i.e. the effect chain in the fx loop is dead as there are buffered bypass pedals inside. The fx loop is serial loop thus at this situation, the amp must be dead silent. But the reality is I still hear a low volume of my playing through the cabinet, this bleed through is normally happened in parallel loop, but why my hjs serial loop also do that? Is that normal as the circuit designed is like this or my jvm is defected?

man, if it had a leslie or even vibrotone simulation it would be almost perfect!!!

OK, so I followed the instructions I found in another answer here about uninstalling the updater and then downloading it and installing a newer version.  Now there's a new error that occurs preventing the updater from working.   I attached the error.  One of the things I looked forward to being able to do with this amp was to record without having to use my Line 6 Pod as a crutch.  However, neither of the programs I normally use (Pro Tools and an older program called RiffWorks) recognize the amp via usb, and I've downloaded some trial software of a couple newer DAWs that recognize it but there's a horrible squealing noise that's produced on top of it (not to mention the guitar sounds like a poor copy of the amp--almost like it's a paper amp).  I am hoping the updater will fix these issues once the updater works.

I recently purchased my beloved amp and one day while on standby i lost all power no lights no sound nada anyone outthere have the same trouble no decent repair shops near me plz help i miss my amp

hey guys,

Hi, I am trying to register this product on your website but it keeps telling me there is no model number. How do I actually register a stanmore speaker?

Has there been a new firmware update for the code amp series?  I just got my new code 50 and I'm having multiple issues. Gateway makes duplicates of my presets then sometimes after editing and saving (either using the amp itself or gateway app)  my amp completely freezes. I have no access to the updater and would like to know if there has been any new firmware updates, and if there is which ones solve these issues. 

What is the difference between  the yjm100-7 and the yjm100-t and the yjm100-u why the different suffixes and what's the meaning . Thank you 

    I have the new Code 50 amp.  I was playing it and it suddenly went silent.  I noticed then the screen was on, so it didn't short out.  Looking into it more, I found the screen had stopped scrolling and all buttons and knobs are unresponsive. I tried (1.) turning it off, then back on, (2.) turning it of, unplugging it and waiting a few moments, plugging back in, then turning it bad on,  Still nothing. I've even tried the (.3) factory reset in the manual.  No avail.  I can plug my iPod into the line in jack and it plays fine, but all the buttons and knobs won't response. Please help!

Hi Folks.....I have a 1987 JCM 25/50 Model 2554.....is it possible to get the owners manual sent to me either to download or by mail?
