Make a copy of your new product purchase receipt (for Warranty Claim purposes) and if you live near an Authorized Service Center (ASC) of ours, give them a call and get your unit plus the receipt to them: http://line6.com/service_centers/
Otherwise, if there isn't an ASC by you, give us a call at: 818-575-3600 (Press 3, then Press 3 and then 2 for an RMA). Our office hours are 8AM-5PM (PST, Monday-Fridays).
