well, right now, my bass is with a competent luthier to have it unwarped! I'm talking about a Warwick Corvette 5 here, that I picked up 9 months ago. Strange thing is, I carefully checked it the shop, I'm not a n00b with guitars and basses, and I know when something is seriously wrong with an instrument. When inspecting it, I didn't notice anything wrong. Last week, I brought it to a luthier, who said that the neck was "paraplu" (****ed up that is). This whole operation is gonna cost me some serious cash, but I don't have another option, it's my only bass. Are there things that can prevent a neck from warping again? I noticed that in a store, basses are put straight up, or hung to the wall, does this have anything to do with it? Can the weight of the body prevent the neck from warping again? btw, I checked for other topics on this subject and I didn't find any..
