Bought a brand new Jvm205h and have no sound. The power switch light comes on but the standby light doesn't.  Took it apart and ohmed all the fuses I could see on the board & the standby switch. Everything ohms fine. All the tubes glow when the amp is on. All switches on the amp work and the footswitch. What am I missing?

Hello!

I have a Code25 and during playback, it just stops sounding.

This happens several times... the connections are good, the proof is that the tuning works perfectly, the signal is going, but there is no sound...

I have to turn it off/on and it sounds again... but after 5-10 minutes, it happens again...

I tried updating the firmware, I tried resetting to factory settings, I tried resetting the presets... it works for a while, then it happens again...

I think it's not hardware, but software... is there any update or firmware to fix this??

Please help me!
Thanks!

I've bought this year a JCM 800 2210 Lead series head amp from 80's. I've bought it by second hand and the previous owner didn't have the foot switch. I've searched until now but I haven't figured out which foot switch is suitable. Could you please explain to me this? 

The amp is single channel in the front, but has the foot switch channel behind. 

Thanks for your help!

My marshall could not getting charge from las 2-3 days

Bluetooth,AUX ,RCA lights always on, can not do anything

I use D# standard almost exclusively.  Can you change the tuner to use that as the default?  It's a pain having to change the tuner EVERY TIME to that tuning.

Hi,

Is there any differences between a 2009 and a 2024 edition of this amp ?

Would really appreciate any info on this topic

Hi, i was wondering if its too hard for implement an update where its possible to change and upload, onto our code 50 amp, custom Impulse Responses from our  PC , if so im all ears for some technical answer.

given a try through the use of IR plugins in my daw i realized that the amp could actually leap frog in sound quality with this change.

and therefore making it a really good small gig/practice amp.

cheers!

I tried taking it to the dealer for servicing.  no use. they cannot fix it.   I called marshall and they said they have none in stock to replace and to ship it to their HQ. 

the point is,  it starts up and when playing guitar.,  all of a sudden there is a ringing sound that gets way too loud and I have to restart the system.  So, essentially it cannot be used on a stage at all 

damn.

Great little amp. I plan to use it via the emulated out into the band PA.

Question ... What sort of 3.5 mm jack lead do I need ... Mono or stereo? ... It will be going into a mono input on the mixer.

I'm trying to register my new amp for the extended warranty but the page keeps falling over when I submit - any ideas?

Out of the blue while playing a very loud spark sound angrily comes out of the amp, is this a bad preset or signs of doom to come.

There is a problem when I´m recording on PC, that after a short period of time the preset-wheel can´t be used anymore to change presets and after unplugging the midicable that would work just for a short while , but the recording program has to be started again and all former recordings are lost.

Is there a program to recognize MarshallCode as a Marshall- device, like it has been in former win versions, for win11pro?  

Thx for helping

Sebastian

How do I  check my woburn 2's serial b

Number and its authenticity?

Why isn't there a Marshall cover for this cab. I know I can order one from Custom Cab Covers or one of the many other companies that make covers. But I'd rather have an authentic Marshall cover. Thanks.
