First thing I do? Change the strings to my own prefered gauge, and have the guitar set up properly. Tweak the neck if necessary. Then leave it alone for about 1 week without touching it, letting the neck settle in. Usually, everytime I bring home a new guitar, it's mostly from overseas, and the wood needs to acclimatise. The wood will expand. Frets will "shrink". etc etc... takes some time settling in.
Once it's settled in, then adjust the pickup heights to what I'd like.
THEN I'll play it.
