Long term guitar storage - neck tensions ?
Hello, thanks for having a look at my question which is kind of more about "wood" and time.
I recently took on a maton 12 string circa 1967 , that had been stored under a bed for 20 years. It had been stored unstrung. The owner just wanted it made playable again if possible. On first assessment I noticed the neck was in a sizeable backbow condition, so much so that I thought it probably was not going to straighten out and the guitar would have to be returned to the owner. However, after releasing the seized-up truss rod nut and left for a week or more, the backbow eased to where you'd normally expect a 12 string neck to be, when for example, routine changing of strings. I assume that means that the neck had fortunately not taken on a permanent set. This has got me thinking about long term storage generally of (especially) 12 stringers. My question is : As well as loosening the strings, should the truss rod also be loosened and if "yes" ...how loose? A second related part of the question might be : when does storage time become "long" term storage?

I normally don't completely detune a guitar unless it is to be stored for at least two years. If you do detune, there is no reason for having any tension on the truss rod. With a two-way rod, you need to find the null point, since loosening too much can induce a back bow. Also, it's a good idea to remove the nut and lubricate the threads of a one-way rod. That is not an option with a two-way rod.
