What do most folks do when adjusting the truss-rod: Just adjust it? Loosen the strings before adjusting it? Truss-rods make me nervous. There always seems to be a bit of “play” between the Allen-wrench and the nut on any bass I have ever had (starting with Fender Jazz in ‘73). I use the proper size wrench, and even try a few different brands since tolerances differ. My rod turns OK, but still wondering. In my current case, I have one bass, with a double-action rod. In the 70s, I stripped the bullet on my Jazz, but I was a dumb kid, and had WAY oversized strings on that thin Jazz neck.
