I live in Middletown NY.... the store that told me about the wood block was Alto music. I've been trying to learn as much as I can about setting up guitars and this seems to be a common practice for some people. Unfortunately the guitar gets cold and hot throught the day. I need to get a good case and keep it in the warm parts of the house. I do think that it is a contributing factor and when I play I usually just mess around on the strings for a good 15-20 min before I tune up and practice... seems to help too....
