After software update Marshall code 50 hisses and has noise


Does anybody else have a noise issue after an update on the firmware?

My Marshall code 50 was dead quiet until I have made an update on the firmware.

Hi JJ,

Thank you for your message, this is not something we have come across before, we would recommend getting the amp look at, and would suggest contacting your dealer.

I've not performed the software update as yet. Perhaps I'll avoid doing so if it's going to casue a problem. - Chris Davies 08 Oct 2018 at 06:24 PM
