His beloved guitar

He was the happiest man on earth when he finally bought his electric guitar. He has been wanting to have one since high school but only pushed through when he got a job. However, due to his busy schedule at work, he seldom play with it. One Sunday morning, the brother thought of checking his favorite instrument that is hanging on the corner. He found out that the gold guitar knobs are fading and falling. Well, it has been years since he bought his guitar. It is time to buy replacement to make his guitar as good as new.
