Pretty sure it was Sheldon himself that mentioned 40-45% humidity is perfect - i keep a small humidifier in my music room - set it at 40% - i refill it when it blinks - usually every week to two weeks - seasonal. I have an array of acoustic guitars that my grandfather hand built plus all my gear - so i try to keep it constant as best i can - to eliminate acoustic wood cracks and fret sprouts - i don't think much happens bodywise with electric instruments - just fret/necks - and that itself is minor if ya keep an eye on it.Good question they're asking by the way : "Is anybody using a humidifier to store their bass?"
I usually see people having problems with too much humidity for instruments (or gear in general), but not enough .. ?
Will the wood develop problem if the atmosphere is too dry ? And if yes what is too dry, then ?
My most tinker-less necks are my Dingwalls, my Wal...and believe it or not...my uber cheap Yamaha that i bought to practice refinishing on - that i can't bring myself to do now. lol
. I miss it.
