I bond with my instruments by spending the first few hours of ownership woodshedding on it and then setting it up. I buy a lot of basses second-hand, so most of them need help in one way or another (new strings, fretboard needs oil, or the setup needs some tweaking). Then you go out and make some memories with it. My Schecter Stiletto Studio-6 was my first sixer, first bass with EMG pickups,and it was intimidating as hell to play because it was the size of an aircraft carrier but eventually I conquered it. My Squire MB-4 was a cheap bass I bought to beat on in Iraq, but damned if it won't go to the grave with me because it is so comfortable for me to play, I love the Skull N' Crossbones paint job, and it has a great tone to it.
