Hi. I'm new to the forums here but I have a question about truss rod adjustment. I have a Squier Affinity J Bass and have been having trouble getting the truss rod adjusted right. I bought the bass about a year ago and found that the neck had too much of a bow to it, so the strings were closer to the neck at the 20th fret than at the 12th fret. I adjusted the truss rod to fix this but it took about 1 1/2 turns to get it right, which I thought was a lot. Since then, every 1-2 months the neck seems to get the bow back in it like it was when I got it and I have to re-adjust the truss rod another 1/2 - 3/4 turn. It would not be a huge deal except that it makes the action quite high around the 12th fret and seems to cause some intonation problems. Is it unusual to have to keep re-adjusting the truss rod like this? Should I bring it to a pro to be set up correctly? TL;DR: J bass neck keeps getting bow in it, have to re-adjust truss rod every 1-2 months. Is this normal?
