I took my Spector Euro 5 to someone who appears to be a knowledgable tech in Southern NJ (graduated from a luthier school out in AZ). I watched while he performed a routine setup and I thought my head was going to explode when he rested the headstock on the bench, grabbed the neck in the middle and near the end of the body, and leaned on it to flex the neck -- this was after he adjusted the truss rod. It's not like he was about to snap it in half, but it DID creak a bit. He noticed the look of utter horror on my face because he said "It always freaks people out when they see me do this." He rationalized the neck flex by saying that truss rods sometimes have a tendency to bind, particularly when they're new and the glue used to put the neck together ends up in the truss rod cavity. Sort of like a trying to open a window that's been painted shut, I suppose. Is this even a remotely sensical practice? Or is this dude a complete charlatan in danger of killing my $1600 bass?
