Since I am becoming obessed with guitars and building a few, lets discuss the neck fit. I talked to a few people who said that the best guitars they have owned had very tight and perfect neck pocket fits. All of them even said that it goes against the thought that it shouldnt be so tight because its bad for the wood when it expands and contracts. But they said for some reason it always ended up being the best sounding and sustaining guitar. I am interested to see if there is a science to this or if its just trial and error. I plan on buying 8 necks and 8 bodies and just start matching up quality, woods, fits, and then pickups and finally the test of does it work? I figure I will learn a lot, have fun, get annoyed, but have at least 4-5 guitars that turn out great.
