I wanted knobs that had a more substantial feel to them. Playing Telecasters conditioned me to barrel knobs, no skirts or numbers needed. I like the feel of these knobs. Yes, they have a little indent on top. If you are so inclined you could put a drop of paint there or glue a tiny jewel. I'll leave mine plain. These knobs are for coarse knurls. Check your guitar for coarse or fine knurls before ordering. I thought about the gold colored knobs, but I wasn't sure how they would match the brushed gold pickguard. The nickel finish reflects the pickguard so they take on a golden color. It's a small visual change, but I think it makes a difference. Get these and see what it does for your guitar.
