Functionally I have been a one guitar guy, because most times in my life I have only one guitar with strings and wiring on it, and one other in storage. But I'm totally sick of every repair or mod meaning I can't play in the meantime, so I'm going to make sure I have two working guitars as much as possible, so if I really do want to tinker on one, as is too often the case with me, I can still spend part of the day practicing.
