Hi everyone,

Do you know in wich year does the jcm800 4104 Vertical imput as been producted..?

Thank you

how do I find original replacement parts such as ohm pin for pin socket/input/output jacks/small logo for amp head?

My amp is a 30mgfx and when I turn it on I need to move the gain to make it sound good and the power of the volume is not the same as when I bought it, what should I do?

Hello.

I have a marshall JVM 410 combo, and connected a extension cab JVMC 212,16 omh,I get an amazingly god sound.

Can I connect two JVMC 212 cabinet without damage the amp in any way? If not,is it a another way to connect one more cab?

Maybe I can use two 8 ohm cab?

I maybe ask silly no, but hope it is possible?   :-)

Thanks for reply.

Does anyone know a way to combat the huge jump in volume when switching from Clean to Crunch on the Classic Gain channel? I’d like the switch to be as simple as pushing the button without the need to alter volume settings.

can you recomend a new set of vaves for my c5 01? also, do i need to have the amp biased when changing the el84? thanks.

When I save to a user preset (blue side) in the app the preset will multiply as in there will be more than 1 of that location and none can be used.  Is there a way to delete a preset or can you tell me what is causing this to happen

Fuzz pedal.  I love my CODE 25, but I'm a bit surprised that a fuzz pedal was not included in the "distortion" section of the pre FX.  I hope Marshall corrects this with the next firmware update.

is it possible to add speakers to a dummy cab?, does it performs well in that case?

Hello, is there a downloadable manual avaiable for the MG100 HDFX?   Also, what footswitches are compatible with it?

Thank you.

hi

what is the model number to use when registering my new mini jubilee 2525c combo. The box won't accept 2525c and nothing helpful is listed.

cheers

Hi, 
I´m in Bolivia, we do not have a Marshall Technical Support Center here.
I own a JCM 2000 TSL 122 combo, and my technitian said I need to replace the Bias Card.
Where can I get one?
I´m going to the US in about a month and would like to have one all ready purchased befor that.

Best Regards.

What are the Preamp tube positions from left to right (looking from the rear of the amp) and what do they control? Thank you

 The 2555x user manual says that the d.i output is frequency compensated and meant to be used to feed a mixing desk or a slave amp but I find this confusing because the frequency compensation is usefull only in the first case and probably really bad if you feed a slave amp and cab.

can you elaborate please? 

When will the Marshall Code 50 be release in the UK?

Hi.  A friend of mine goes to London next month.  Can you tell me where can he buy for me a power stage pcb replacemente for my tsl122? Thanks!!

Hi , please advise what rectifier is used in Silver Jubilee Mini 2525H  - solid state or tube? Thanks!

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. 

I've downloaded the firmware updater onto my Windows 7 (most recent updates loaded) PC and it seems that there is no eligant way to close the updater after use. I had to use ProcMgr to force the updater to shutdown.

I also found that unless you do things in the correct way - fire up the updater tool before plugging in the USB, it seemed to get very confused - again I had to use procmgr to close it down.

I recently bought a Marshall 2x12" Cab with Marshall Goldback speakers mounted, type SPK100, 8 ohms, 80W each. As Marshall does not make speakers I am curious who the manufacturer is. The speaker's cage does not look like a Celestion. It seems to be an Eminence at first glance.

Does anybody have any information? Thank you!
