I have a JMD1 combo, it works find when I used headphone but just no sound from the speaker. I have tested the speaker and it seems the speaker itself is functioning

Which amp is best-code 50 or the valvestate 8040 best opinions? 

Hi  I am new around the forum.  

I have written software in the past for editing Alesis quadraverbs and want to do something for my JMP-1.  Alesis published their midi communications protocol but I haven't found anything for the JMP-1.   Does anyone on the forum or at Marshall have something they can share please?

thanks

Phil

Bought from Cashconverters a year ago,after initial boot up found it didn't switch from green to red without a nice big echoy fart but red to green ok.

Took amp to a local tech but he couldn't sort the prob.

I've done a bias upgrade on a dsl50 and was succesful so if you have any diy ideas that I could try,please feel free to send.

Ps...I hearby exhonerate you from any faults that may occur.

Kind regards,

Paul.

Ps...I've read the RL1 in a tsl has fixed a similar issue.

Recently updated the firmware for my code 50 and it stopped short of complete firmware installation when I received a pop-up to restart the installation. The amp is stuck at ready to update but now the firmware won't install again. Tried a factory reset but now the amp will say USB not connected...until I reconnect....then it will read... ready for update. Which won't update anymore or resume where it left off. Can I get the original firmware or another way to factory reset? Buttons will not activate anything anymore.

Hi – just wanted to check something please in regard to using the emulated line out on the JVM205H. My question is could I use my JVM205H and take that to rehearsal without the cab and go straight from the head to the PA and as long as Standby is off, then I won't damage the amp in this configuration. Is that correct?

ayuda con preset para el solo de audioslave like stone

I turned all of the presets off, all i want is a plain Plexi or hot rod amp. I have my own reverb and my own delay and EQ. So I took Marshall Fury Lead which sounds pretty good and turned all the other stuff off...

then when i get app. on my phone turned on it goes and overwrites the preset on the Code 100 head. ??? wtf? Now its noisey and feeding back an out of control.

I cannot risk having an amp that squeals and changes presets like that without me asking it. There are too many settings too much to go wrong. 

I am starting to regret buying this thing.

How do i fix it so that the preset stays in the cloud on the amp and everywhere else forever!.. Until i change it...Can anyone please help with that?

its a 100 watt Code. I just want it to be a dirty power amp, no cab simulator nothing...

thanks, NIck

Hallo an alle,

weiß jemand warum der Code 100 nicht mehr angeboten wird?

Hi, I own a MG50DFX  amp. Marshall recommends PEDL-90004 but this pedal is almost out of stock. Which other pedals could work for this amp? Does PEDL-90003 works?

Thanks.

Hi I have a Marshall code 100 combo amp and wondering how to up date my amp if you can up date my amp? Any help would be apperciated.

Suddenly, Bluetooth stopped working right on my phone (Huawei P series)  while I'm playing...  Amp is updated to latest version and every time i want to change preset surprise! The phone is unpaired, it needs to reconnect again... but guess what? Now the screen on my code start blinking, not red or the buttons either, but it blinks like if loosing power or something... I don't know if it might be an electrical issue or it's just a lose cable inside that needs a check. 

Woburn 1: The Musik plays a view Minutes. Than a soft slow, cracking Sound starts. The cracking Sound gets faster and louder. After a view Seconds you can´t hear anything. No Musik. No Cracking. Than the Musik continues to play. In irregular Intervalls of a view Minutes the Cracking starts again. Even if no Musik play the cracking starts after some Minutes, gets faster and louder ... I would like to fix the Problem at home, but I need help.

alguien podria ayudarme con un preset que emule el sonido para el Solo de Audioslave Like Stone

Please answer quick!

I don't want to always use my phone when playing. There used to be a way to save presets directly in the amp but I can't seem to do it anymore. These past updates have really screwed up the code amp for me. It doesn't seem like any of the support videos are accurate any longer. 

I know there is an input on the back panel and I think I have a cable to use, but I have an iPhone 13 and want to use Spotify to play along to. How do I do the hookup?  

I recently got a Code 50. After a few weeks of using it and learning the my.Marshall website, I realized it did not have any of the newer firmware updates. I updated it with v. 1.47 and now I do not get any guitar sound. I get sound from my phone when it's connected via bluetooth. How can I install the previous version of firmware?

I tried using the foot peddle cable to see if it is a cable issue and strange things happened. I hear some strange music broadcast. Not sure if some neighboring device connected to my amp via bluetooth. Is there any way to turn bluetooth off and on?

I tried doing the factory reset and it does not reset the firmware. Is it supposed to reset the firmware with the factory reset function?

Thanks.

UPDATE: I got this resolved. It turned out to be an issue with the guitar.

Why is there no profile save button in ios and when there is a drop down it doesn't work, for example om the overdrive peddle you can't select GUV ODR or DIS it just pings back to what it was set on.
