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

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.

I have a JMP-1 feeding a Valvestate 8004. Should the Master output be set at +4 or -20 db? Thank you!

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.

How to add / change thumbnail pic for a preset ?

Is there a specific way I should be using these volume knobs ??? I like a gritty, crunchy, clean sound. Like 70's -80's bands. Bad Co, The Baby's, Foreigner

I purchased my DSL40CR in Sept 2020. Its never left my bedroom, never been played particularly loud and (unfortunately) I have not had a lot of time to use it.  The presence and resonance originally worked when I received the amp but now turning either of these two knobs has no effect.

Also there has always been an occasional, infrequent, weak 'crackle' noise.  Is this a tube problem or is this normal for this amp?

Is there an 'easy' fix, like swapping tubes?  Is that something I can do myself?

Please let me know what my options are.

Thanks,

Dean

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

Hello, is there anyone who has made a Volbeat preset yet.

I'm just a rookie so I'm not experienced enough to create one myself.

new purchase. I have a custom Eddie Van Halen replica orginal. Excact copy of the famous Frankie. 

I have spent time on the app and making adjustments however I dont get the sound i was hope for. Perhaps I need to add an FX ex Boss ME-50. To get the sound i am looking for.  ACDC / Kiss / VH. all i get is a little louder version of my guitar. I have watched many videos on line and they change the setting and get classic rock sounds. Like a Gibson or whatever. Classic rocks sounds.  I have tried many VH and ACDC pre programmed set ups and still not he tone i am looking for. What am i missing?

Thanks 

I'm assuming I have 100 slots on my CODE 50 for whatever presets I choose. How do I specify which numbered slot I wish to update or change with any of the presets on MyMarshall.com. Not sure if this question makes sense or if I even worded it correctly. 

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.

Dear fellow Marshallers,

I have recently bought a Marshall DSL15C amp for my guitar and was looking to use headphones for silent practice. I tried disconnecting the amp output on the back side of the speaker and plugging in my headphones instead - this doesn't seem to work perfectly as my headphones only play in one ear and the sound is crazy high. 

Is there a good way to use headphones on this amp or do I need to buy another amp for silent practice?

Rock on,

Magnus

I have a DSL H and two 1936 Cabinets. What is the proper way to hook these cabinets up to my amplifier

I can't figure out how to register my new Marshall Amp on your website???

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. 

Haven't been able to find a source that offers suggsestions on replacement tubes for the DSL20C. I'd like to have a couple sets of backup tubes and if someone has any info on sound/effect of a particular tube or tube set that would help. The youtube videos I've found only mention groove tubes which I believe the concensus was that those tubes darken the sound. Any more info on those or other similar tubes would be of great help.

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

my code 25 is frozen, nothing is working. The display shows marshall - MCU: 1,47

Connection to the pc is working, update is starting, and then please wait restarting code.

Nothing more. The code 25 is not restarting. Power off and on is not the solution

What can I do?
