HEY DUDEZ!
I figured I'd 1-up you all. I put 2 dessicant bags in my guitar case for 2 months.
Guess what?
My frets popped up and my intonation went whack. Buzzing happened. It took an Elegee day to fix. I also noticed the grain in the fretboard became more apparent and it looked really dry/bad.
If your fretboard isnt as dry as it should be ata, dessicants can be harmful. I suspect the dessicants pulled out the remaining moisture in my fretboard and made it contract- thus the frets popped-up slightly.
