Gift For A Guitar Player

I have been cracking my head on what to get for my cousin’s birthday next month.  He is throwing a party to celebrate his 30th birthday.  Since he loves to play the guitar, I thought it would be nice to get him something that is related to it.  I was browsing the online shops and found some guitar strap locks which I think he would like.  I also saw this cute guitar pendant from Merrin & Gussy which is just perfect for a music lover.  I think I want to give him not one but a few gifts this time.
