In an effort to assist our customers who've had their Line 6 gear stolen, we have implemented a feature where registered gear can be marked as "stolen".
Navigate to the list of Registered Gear in your Line 6 account
Click the Edit icon next to your stolen unit's serial number
Click the "Report Stolen" link next to your product's name
Click the Confirm link
A unit marked as stolen will now appear as such within Line 6's registration syste
