Why can't I register my CODE 50 online? On the physical card it gives the website, marshallusa.com/warranty but that link does not work. In the forum you addressed that by telling us to go back to the dealer. WTF is up with that? Having to fill out that tiny card and mail it is BS. Unacceptable.
Please email your warranty details to email@example.com , and we will get these registered for you.
