Leaning guitar "fretboard side" against a raised surface
I have played bass for years and have encountered a few people who swear leaning your bass, at an angle but still "standing" up, against a surface (amp, couch, counter, whatever) with the backside of the neck being the part that makes contact will "bow the neck". These people usually lean the bass/guitar fretboard side making contact with it.
Now, I don't usually leave my basses in this fashion for longer than a minute or two, usually in the instance of a bathroom break or to grab a drink anyway, but I want to know if anyone thinks there is any validity to this. I personally never thought it made any sense, considering the construction of the neck and the fact that I don't see how the same effect wouldn't occur regardless of side.
A newb question, but I have never asked it!
