Hey everyone, I'm a DB player who is crossing back over to the "Light Side" by getting my first quality BG in a while, a MIJ mustang bass I got used. I really like the bass, but I'm having a little issue. My neck is doing a subtle backbow causing the lowest few frets to be a little buzzy. I took it back to the luther I got it set up at, and he said it was backbowing, probably due to the season change and the fact that is is a new-ish bass. It keeps reverting back days after adjustment, however, and won't "hold" the setup. I'm inclined to begin just adjusting it myself but loosening my rod a little, but I have some questions about truss rod care. Will I eventually reverse-max out the rod by loosening it too often? Is there the chance something else is happening with the bass? Thanks for the insight, guys.
