hi all. I currently own 2 PRS Core guitars. A 2018 Custom 24-08 Artist with a rosewood neck and Brazilian rosewood fretboard and a 2017 Custom 22 10 Top with a rosewood neck and ebony fretboard. My question is, I've never had to adjust the 24-08 neck, but almost every 4-8 weeks I need to adjust the 22's neck. Both guitars sit side by side 6" inches apart in the same room, what's happening to the 22 neck - any ideas why it needs constant adjustment? Could it be a defect in the neck wood? Thanks.
