Would you know kung ano effect kung too dry? Nilalagyan ko ng silica gel packs (galing box ng running shoes hehehe) yung guitar case ng wolfgang ko pero worried ako baka too dry kasi medyo dry na rin dito sa mpls lalo na kung winter.
I think you will need a lot of those packs to create a very dry environment in the guitar case to cause problems. Kung sa case mo tinatapon yung mga pinupulot mong "Do Not Eat" packs like I do, I don't think that would be a major concern. If it's too dry, the wood contracts. Contraction/expansion of wood is best seen in the most unprotected part of the guitar - the fretboard. Kung dry and the wood contracts, you gut "fret stubs" (it's called other things as well) wherein the frets stick out of the sides of the fretboard since the wood contracts and the metal frets do not contract as much. Some people find this annoying. Ako, nasanay na ako to expect it during winter. Baliktad naman kung moist yung environment. From what my tech tells me, its the sudden and frequent swinging of temperature and humidity from one side of the scale to the other that causes problems - both good and bad. Good in the sense that it gives that "cracked" relic finish that people pay big bucks for or do funky things just to speed up the process. Bad in the sense that warpage could take place. That's why techies suggest that you acclimatize your axe when you go from one end of the temperature or humidity spectrum to the other before using it.
Is it better to store your guitar inside it's case or just place it in a stand?
Personally I'd say case, by a mile. It could be a bit cumbersome but I find it a safer method in more ways than one.
