Good semi expensive priced gift for guitar player?

A new manager that works for me has done a really fantiastic job and want to get him something good. I don’t know him super well yet but I know he plays guitar and loves music. What are some ideas for what I could get him? I really want something that shows that he’s appreciated and valued, something that just blows him away. Any ideas appreciated!

Automod keeps saying it will remove the post if I write numbers, I am thinking in the two to three hundred dollar range. Might spend a little more is there was something really exceptional.

**One thing I was looking at is the Soundbrenner Core two watch tool thing. Looks pretty cool but I haven’t heard of it and sometimes those things sound better than they really are.

Thanks!
