only sticker on my amp says v02011171u 07-17
warranty card needs x-xxxx-xx-xxx-x format
Hello James,
The code serial number is only 10 digits long , so just fill out the warranty card V-02-011171-U.
but the webpage and waranty car require a number with a pttern as i stated above how does the code fot that pattern the web page wont accept your choice.!
If you go to the Marshall website and scroll down to the bottom and click on Register My Amp you are able to write your serial number in there, it doesn`t have a set format that you need to follow.
On the warranty Card it has a blank space for the serial number.
