Being a teen is a time of discovery. Going out of being a child and going into adulthood, teens are often confused especially if there is no proper guidance from within the home. It is also a time for parents to be more on the lookout for them because peer pressure could be so strong that they can pull your child into bad vices.
Learning how to play a guitar is almost always cool for any teenager. When they learn, they need not be with a group to be able to perform well. They can play solo if they so wish, up in their own rooms, far from bad influences. If you give one of the ibanez guitars, you might not have to wonder where your teen is.
