Several times now, the Code 25 has locked up on me when trying to use it from the Gateway App on my iPad.  Symptoms are that the display will freeze up (text no longer scrolls) and the different buttons (including gain, tone knobs, etc) will become completely unresponsive.  Controlling it from the iPad will no longer work either.  The only thing I can do at that point is switch the amp off & on again.

Additionally, trying to connect the app to the amp is really hit and miss (yes, it's paired successfully):  sometimes it refuses to work, sometimes it will freeze the amp and sometimes it will work, but switching from ipad to amp presets will not. 

Hello,

I am a recent ower of a Marshall Origin 20, which I got in July. I've really enjoyed the amp until I plugged in last night and got out absolutely no sound out of it. I couldn't figure out why, as nothing as happened to it and it worked fine two days ago. I took it apart to do some trouble shooting and found that when I have all the knobs max'd and output on 20 watts, I can hear a whisper of my guitar signal (nicely saturated, presumably by the preamp tubes) through the speaker. This sound is affected by all of the knobs. However, if I plug my guitar directly into the return of the effects loop, and activate the effects loop I get no sound whatsoever; no guitar, no hum, nothing. Because of this, I'm sure my speaker is not the problem. These things led me to think it was a power amp section issue, so I went down and purchased a new set of matched EL34's, threw them in there, and nothing changed. I'd really like to know if there's anything I can do to fix this, because this amp is not even a year old and I should not be having these kinds of problems with completely normal bedroom use.

Thanks,

Alex

I have had my JCM900 4x12 1960B cab since the 90´s and would like know when it was manufactured.

The serial number is 09649.

Thank you!

Hello everybody.

I just have one quick and easy question: can I sweep a couple of KT66 power tube instead of its original 5881 in my JTM45 2255 reissue head?

any risk or anything to set?

thank you all in  advance 

kind regards

My DSL started to misbehave after about six months since I bought it. When I turn it on, the tubes don't light up so the amp itself does not produce a single sound. Now, I have tried to send it back to the store where I bought the amp but the damn thing magically started to work there in fornt of the repairer so he said that he could not find what's wrong with it. The problem occured a few more times so I contacted one of the local electricians and he did the job and the amp finally worked. After approximately two months the same problem occured so I asked the same guy who fixed it earlier to fix it again, and again it worked. Now after a month or so, it has happened again. Has anyone experienced a similar problem? I need some advice. Thank you :)

Does changing from one wattage to another while the amp is on cause any problems?

It doesn't seem to cause any audio issues besides the obvious change in volume - but will it hurt the lifespan of the tubes or damage any components?

So what's the rule? Choose power level before turning on? Turn down the master volume before changing power levels? Or does it make zero difference?

While waiting patiently to see if / when the CODE100 amps. are going to be available I happened to look at the supposed specs. for the CODE100 on your (Marshall) website found here: https://marshallamps.com/products/amplifiers/code/code-100h/

I couldn't help but notice that the CODE100 will allow 5 x simultaneous FX to be used.  As we are all aware: this is not the case with the CODE50 and CODE25 i.e. only 1 x FX may be used.  Aside from the obvious physical difference and output between the CODE100 and the CODE50 and CODE25: everything else appears to be the same other than the number of simultaneous FX that may be used.  So my question is: is it not just a simple firmware update / upgrade that will allow for 5 x simultaneous FX to be used with the CODE50 and CODE25???  If so: could we have it please (or could we at least have some input or further information on this)???  In hindsight and as wonderful as I think these amps. are: it's starting to not make sense to me that I still have to purchase stompboxes if I want to use, for example, a compressor, additional distortion, and, say, an octave (pitch shifter) when all of these FX are actually included on the CODE50 and CODE25 but only 1 x FX can be used at any given time.

Dale.

The Amp model 2555x doesn't exist... Or I put wrong product code for this amp (begin with 255...) ? 

Thank you !

hallo Marshall team,

please can you tell me if the DI/Out socket can be used also with headphones?

is it confirmed that once I connected the DI/Out to a mixer PA or a Audio Interface, I can un-plug the speaker cable fro the amp without damages?

thank you

regards

Hi all,

Is there a parts list available somewhere for a JTM 30 amp??

Hello everybody I'm looking for Hotel California solo by Eagles tone thanks.

I just got a Code 4 button footswitch for my Code50 amp but it does not do anything. No lights, nothing.  Do I need to do anything to the amp to get it going?

Hey 

I noticed this a few days ago. When i plug in my 2525H head and run the overdrive channel, there is a very strong loud (sounds like) electrical noise. It goes away when i remove the pedals hooked up into the loop. 

Now i run a couple of EQ's, mxr 10band eqs on 18v power and a DD7 delay pedal in the loop. I have checked each pedal individually and also changed the cables used and it doesnt go away. 

I also checked if its a power supply issue, i run a t rex fuel tank chameleon that powers all my pedals, the 18v jack i have used a daisy chain to hook up 3 pedals, a Fulltone OCD, and the 2 eq pedals, i checked the power draw on each and it is wayy within the required power that is given out of that 18v socket. 

Please help, this is recent, i never had this problem before. I've gigged with this amp on a few occassions too, noithing was noticeable, and with this issue its very noticeable on low volumes as well. 

I have a couple legacy amps. A JCM 900, and a JCM 2000 DSL 50. Somewhat surprised to not be able to find some PDF files of the manuals on the marshall website. Am I missing them ? A "discontinued" section ?

Thanks!

Bought a Code 25 few days ago.  Plugged into my computer via usb, using garageband, and the funny thing happens. First, garageband does reconize the amp, however, no sound comes in or out. The volume on the channel of the amp won't work either.

Anyway, assuming it was a conflict between the amp and garageband, I tried it on reaper. Same problem, DAW reconizes the amp, no sound comes in or out. 

Another test, the firmware. Did upgraded it, nothing happened again.

Any solution? I bought this amp exclusively to record via usb, and the main function for me isn't working. Dammit!

Goodmorning,

I've bought a pair of marshall major III bluetooth and I can't use the bluetooth mode: after the first charged the red light is fix untill the headphones end the battery. I can't turn on them. What can I do? The seller dosen't answer me.  Is there a way to reset them? Thanks for your answer.

Best wishes

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 ?

Hi, I've just received the headphones and they sound really nice. But I can't connect them to my Iphone for some reason, I turn on the bluetooth on them and on my phone, but they do not appear on my phone, it can't find them.

Any chance you know about this kind of situation and could give me some advice?

Thank you.

Hi. I have bought the Marshall Code 212 cabinet with 8OHM. Now I want to buy Marshall DSL1HR tube head with 16OHM. Can I connect 16 OHM head to 8 OHM cabinet? Thanks in advance
