Hey everyone! Soooo let me ask a question to all of you guys and gals that dabble with guitar. I have a Yamaha FX335c acoustic-electric. I've had it for a few years but I've never stored it with those humidity packs in its hard case. Is this something that should be done regularly? When its not getting used its stored in its case and is away from exterior walls. Just a thought, and input would be greatly appreciated!
