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.
Thank you for you message, we are sorry you seem to be having issues, we have passed this to our tech team to look into, just to check have you tried another guitar or lead, or been back to the store for them to test this, your warranty is with the store and they will be able to advise on a repair or replacement.
If you would like to email firstname.lastname@example.org , and we can correspond directly.
Comment WITH VIDEO to follow!!! LOL!!!
This ain't going to make you feel any better but here's what one of mine sounds like clean i.e. with everything off:
This recorded just with the camera's mic. and for this little excercise the Master Volume was only on 1 i.e. just above the point where it "kicks in" (ye olde Master Volume issue TEAM MARSHALL)!!!
Sounds real clear to me (actually they have a lovely clean tone even although it's something I never ever use).
With all that buzzing you're getting and the sound I'd say with confidence it's defective (I have five CODE amps. and never heard anything like that out of any one of them at ANY volume). Only thing that's odd is the fact that with headphones it sounds fine.
Anyways. I hope you get it sorted. They're wonderful amps. Judging by some of the posts around these parts there just seems to be some duds out there and maybe yours is just one of them unfortunately (because you say it's been like this since purchase).
