When we ship a guitar we always send it with instructions to the courier that a signature MUST be obtained at the time of delivery. If no one is home to sign for the carton, it will not be left. We do this to ensure that your guitar does not fall into the hands of porch pirates (or other nefarious characters such as bass players or drummers).
UPDATE - We've learned that during the COVID-19 crisis FedEx is sometimes leaving cartons with no signature. Please follow the tracking number we provide to make sure you know when your guitar arrives.
