Hey, I just removed the neck of my MIM Fender jazz, as I'm going to replace it with a Warmoth neck. Unbolted, with no string tension, it definitely has some backbow to it. Should I loosen the truss rod to straighten it out, or will it be allright to leave it as is? If I need to loosen it, should I do it a little at a time (as I would if it were on the bass) or all at once (doesn't sound like a good idea). I don't want to ruin it by storing it improperly. Thanks!
