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

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?

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

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 :)

Hi all,

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

Regards,

Gordon.

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

Thank you ! 

Best regards,

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

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. 

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!

I have the Marshall gateway app, a multieffects pedal, a interface Focusrite and a accustom guitar but I can’ get any sound out of the speaker! Help!!

Hi, I just want to make sure I've got this straight. I want to run my amp through my external attenuator(weber mini mass) and then into an 8 ohm external cabinet.

1a) Amp (8 ohm out)->attenuator(set for 8 0hms)->to external cabinet(1x12 with 8 ohm speaker) Is this correct?

1b) In the above scenario, if I want to run through the 8 ohm cab alone do I have to disconnect the onboard 16 ohm speaker? 

2) If the external attenuator is not connected, can I run the amp through the 16 ohm combo speaker and the 8 ohm ext cab at the same time? Or is it either/or?

Thanks

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!

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?

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 good morning I just want to ask if this product is authentic since its a marshall site is there any chance you can check if this code is real or not just verifying my marshall product both , here is the product code  7 340055301046, and 7340055309400.thank you 

I am connected to my Code 100H via bluetooth and using Marshall Gateway app and trying to play a song using the playback feature and the song will not play. My music library was found and I can pick the songs ok and they appear in playback, but will not play. I just wonder if this has anything to do with Apple Music?

I am using my Ipad and also tried with my Iphone 7.

Frustrating, please help!

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 ?

I may be doing something wrong. However all the sittings ive tried all sounds muddy/ muffeled. I play alot of metal music and it just sounds a bit off. Could someone possinly help me?
