Yep, Clay made up a set of five cocobolo hat knobs for a bass last year, and they look incredible. It adds so much class over standard metal or rubber knobs! {}
Hey Lonnybass As a long time admirer of his work, I may have him make up some for me for five prototype builds I have in the works. I am trying to get this type of DIY inserts to make my own, but the company that sells them is out of stock for a while now. I can't find them anywhere else. {} I am really partial to the push on split shaft type as opposed to the solid shaft set screw type. Hard for me to believe how many nice options he has on his site though. High quality work with a lot of sizes and diversity, and he will custom make whatever you want.
