To a non-guitar playing person, a guitar is just a guitar, with not much of a difference.
To my sister, who has been hankering for a guitar with a semi-hollow tone but has been complaining that the one she is currently playing is too bulky.
While browsing the internet this morning, I came across this Gibson's ES-339 guitar and brought her attention to it too. She is so excited, and claims that it is just what she has been looking for.
Her excitement rubbed off on me too and I think I want to get it for her.
