Hi, so there's a high pitch whining sound coming from my amp both with and without the guitar plugged in, I believe it started around when I first tried the in-built bluetooth feature and think this is the reason for my troubles. The whine starts at 10% on the master volume knob and progressively gets louder as you crank it up

When I tick the 'share audio' button on  my phone, the whining stops, and is replaced by a very managable amount of noise. 

I've already done a factory reset to try and disable bluetooth but the whine is unchanged and bluetooth is still on. I've also tried disabling all bluetooth devices nearby, shutting off my pc, taking away my phones and switching wall sockets (although I haven't tried outside my room yet).

Is there any way to disable bluetooth on the CODE 50? Or maybe I can take it apart and remove the transmitter myself.

Here's a demonstration of me turning on the amp and moving the mic closer (Master volume at 100%)

Hi everyone!
im a Marshall code 50 owner.

i was trying to record my guitar via USB using GarageBand, but it was not possible.

I setup the input as Code in GarageBand but doesn't work.

any suggestions? or maybe Code doesnt work with GarageBand?
can you recomend any interface (not an expensive one) to record my guitar?

It is quite easy to reorganise presets using the My Gateway webpage, which then syncs to the app. However, I like to keep my presets on the app and amp the same, and it is quite arduous to transfer them all manually, is there any way to transfer all presets from the app to the amp at once?

When I connect my Code 50 to my PC via USB, it only plays the left audio of music but not the right audio. This problem does not persist when connected via Bluetooth to my phone.

Can I use bluetooth headphones with ampli Code 50 to play guitar and listening it? I have bluetooth headphones but don't works...

Can you use a wah and then have another pedal for another thing? Does this even make sense ? Do guitarist even use 2 pedals ever? I am so new to this so just asking about some thoughts I have

Latly my Code50 started to sound very un-clear & with lot of vibration (no buzz!) on low end frequencies, especially when I pluck the A & low E string toggether.

Tried different guitars, data cables. elec. cables.... tried repositioning the amp in the room, tried to tighten up all the screw... nothing helped.

Any ideas? could be firmware issue? has anyone else experienced this?

Thanks

Hi, I was just asking myself if I sohuld buy a  Distortion pedal or a overdrive pedal for my Marshall Code 50. 

The amp was not on, nor was it plugged in, so that is good, I'd imagine. Quickly, after the spill, I turned the amp upside down and then proceeded to get the surface liquid off. Should I open it up? Should I simply let it dry next to a heat source?

I have, or should I say, HAD a Marshall CODE 50 which after 20 months of service decided to quit following a POWER SUPPLY failure.  I took it to an electrical repairer for diagnosis and found out, through Marshall Australia and UK that the power supply is not replaceable because it has been suspended.  No parts available.  That means I now have an amp that is unfixable and never will be, even with an aftert-market power supply - which, according to Marshall cannot be retro-fitted.  What a fantastic waste of money that exercise was, and I have zero warranty fall-back.  Has anyone else had the same problem?  Kev

Dear Concern,

I have been a huge marshall user for the past 20 years. I have never been let down by any of the products I have used so far until recently. I bought the Marshall CODE 50 and one year in time something happened to the power circuit unit. I got it checked from the store "World Music" in BD, and they confirmed that the circuit is damaged. I need to buy the circuit but unfortunately, I cannot find it anywhere here. I even checked with Guitar Center in Vegas and they were unable to help me out with the matter as well. Any lead on where to buy such a circuit will help me a lot.
