Using your Fender Custom Shop Postmodern Stratocaster Journeyman Relic is a breeze. First, take it out of the deluxe hardshell case gently. Put on the included strap and start strumming. You can easily tune it with the vintage - style tuning machines. When you're done playing, always put it back in the case to protect it from dust and scratches.
For maintenance, keep it in a place with stable temperature and humidity. You can clean the body with a soft, dry cloth regularly. Every few months, check the strings. If they're worn out, replace them with nickel - plated steel strings of the same gauge (.010 -.046). And don't forget to keep the certificate of authenticity in a safe place, as it's proof of your guitar's authenticity and value.
