After about 3 months of very light usage (home use, ~20 hours), my Code 50 developed a harsh noise problem: https://youtu.be/S2cTK8fsfTE. It's on every preset and can be heard via the speaker and when using headphones. I tried using different guitars/cables/power cords/rooms/outlets, reloading firmware, and resetting the presets to factory default; but the noise continues. Anything else I can try before I return it for replacement/warranty work?
How do I register my new speaker cabinet in the United States?
The warranty card gives me a weblink of www.marshallusa.com/warranty, but when I go there, it says; "EPIC 404! AN EAR OCCURRED WHILE PROCESSING YOUR REQUEST."
Here are the videos of the defect
This amp sounded like this since day one I always thought it was maybe just the effects but soon realised after using the clean channel turning off all the fx and amps and also having people look at it I realised that theres something seriously wrong with it. I tried contacting you guys for that 5 year warranty especially since its defective but have not gotten a response. Its been almost a year that I've been trying to figure whats wrong with it but even person I ask has no clue I've searched and searched and have found no such issue similar to mine. I would like to get an explaination of the issue and see if there is a solution or maybe a replacement if possible thank you.
