I know there are sites which list the density of various hardwoods, but is there anyplace to find out about how they compare for sensitivity to humidity? (what terms to search on in Google)
For instance, I've found that Ebony seems to be very sensitive to changes, but I'm particularly interested in Hard maple, Alder, Ash, and Mahogany (probably the 4 most common electric guitar woods). Which of those 4 is probably least variable to changes in humidity?
And is there anyway to treat hardwood to make it less changeable? (Sealers, hardeners, etc?)
