Answer:
Guitars are not really given out for free since they are so valuable. One might find a guitar in a junkyard for free. Maybe a relative such as a grandpa or grandma wants to pass down a guitar to their grandchild and it would be free in that case. Or if the guitar is extremely damaged, someone at a yard sale may give it up for free or at least at a very cheap price. You could enter in a contest or raffle and then if the winning prize is a guitar then it is not really free, but that is how it can be considered. For the most part, however, guitars are not usually free.
