My JVM 410C doesnt have any volume coming from the channels.

One switch works green yelow, not red.  Works fine with switch two.  Switch three works green and yellow, not red.

switch four doesn't work at all. 

No sound out of these channels without footswitch.  Same results.  Now, making a poping noise when turned off.  I just got htis amp in June.  Played a few weeks and then boom, nothing.

I tried using the FX Loop in back.  That's when this whole thing started.  As I correctly plugged in as instructions say, it immediately didn't make sound in these channels.  Unplugged, guitar going straight in, same stuff.  No volume through these channels.

The tubes are red, all glowing.

I need help.  Thanks.

Just purchased this amp. I am a little suprised at how hot the metal faceplate on the control panel gets during use.  I know tubes generate heat and the DSL40 has the four pre-amp tubes just behing that faceplate. Still, just wondering if this is "normal". This is occurring even in low power mode, at relatively low volumes (set at 2 or below) and the Ultra Gain at about three quarters.

Hello,

So I got these Marshall Monitor headphones from apple over in boston last august and they were working just fine until two months ago when one of the sides of the headphones when out and would not produce sound, so I put the headphone jack in the other ear and it was fine, but then it happened again with the other ear.

I was just wondering if Marshall can fix this problem or if anyone else has had the same problem with these head phones.

What the stock original preamp tubes of this head?

Thanks

Has the support team for marshallamps.com gone on summer recess like the politicians perhaps - I've been trying to get an answer to a question on 3 year registration of my amp for about a month now.

Is there any chance someone is going to date the community questions - at present it is getting bigger and bigger but as far as I can tell its not in date order - So far everytime I come to it it seems that I'm re-reading stuff so that I don't miss new stuff.

Any chance the dates could be added to the initial list page, perhaps a sort function as well to allow sorting of question and answers depending on what people might want. At the moment it seems to be very hit and miss and not exactly in line with the amp qualities.

Hello, since this morning, when I turn my amp on, it gives sound for two or three seconds, then stops while the LED becomes ligther and switch off.

Power supply seems to be good beacause it gives about 18 V DC.

My amp was bought in England and I live in France, so I can't bring it back. What can I do ?

Thanks for your answer.

Hey Nick! Everyone at Marshall!

Given that you're on the right settings, will CODE give me that JCM800 CHUNKA - CHUNKA sound, with a palm muted stroke of the Plectrum? I know, I know, it's a (STUPID) Technical question, but you lot get my meaning, right?Cheers! And see you in hell my friends!! \m/ (Nick's The Man!!!!)

Is there any  CODE50 Windows Software available, besides the firmware update software? -Rod-

can I lock the library screen, it slides back every time I select a  preset

100 presets is more than the avaerage human brain can handle, 5 +/- 2 is the old adage.  The Gateway app when active and syncing with the amp displays "Tap to sync" after the first few preset entries.  So you can't efficiently scroll through the presets. Is there a preset listing anywhere on the Marshall Website a customer can print out?

In a future release of the ios app the presets managed by group such as a catagory/folder entry would be nice, e.g. Metal, Clean, Rock, etc ...

Thanks

is there a software issue with no sound when a user setting is saved?

i would like to return my dsl 100 watt head because i bought it 6/25/2015 and i got it on 8/20/2015 i played out of it about 8 times and the transformer went on it i would like my money back from it  

Hi, I've just bought a Marshall Code 50 which worked 2 days ago and again 20 minutes ago but after trying to pair with (a) Android Samsung phone (unsuccessful) then (b) iPad (also unsuccessful) the amp turned off and now will not turn on. Power supply is working, no power cut. Any advice apart from return the unit?!?!

Hi,

I'm trying to register my AS50D (limited edition in green) but when I enter the model number it gives me 3 options to choose from.  Any chance anyone could inform me which one relates to my amp?

Cheers,

Paul.

Hi there,

I am considering buying a 2525H head and I was wondering if bias adjustement would be required on such low wattage EL34 power section.

I know the 'full scale' silver jubilee have a pot for bias adjustment but it seems not to be the case for the mini version.

Please confirm.

why doesn't my android phone connect to the amp blue tooth?

How can I back up my presets?
