In high humidity, should a properly set up guitar neck have a back bow or a forward bow? The reason I am asking is I went to a local guitar shop and a couple ibanez and schecters I tried had some forward bow in the neck, but the sales guy said its just the high humidity (crazy rain in the past week or so). Also, does a shorter scale length make a guitar easier to play in general? A lot of the schecters I looked at have like 25" scale, and that's pretty long I would say. I also heard that the reason for the long scale is they are good for downtuning, but the problem is, I don't do any downtuning at all. So, would a longer scale length be bad for me?
