These are very high quality knobs but just like everything with a Gibson name on it, they are highly overpriced. Throughout the years, I have purchased at least three times less expensive knobs that weren't much worse. Of course, if you need a retrofit for one of the vintage Gibsons in your collection, then these are probably the most period-correct knobs you can buy, but if all you need is a high quality replacement, it is worth looking around for some more affordable alternatives. Unless your knobs have to have the vintage-correct shape and numbering, there's no need to waste your money on these.
They do fit on nearly every Gibson guitar with the standard pot shafts. They fit very well and are produced in good quality. I think the numbers are not impressed, which is not historically correct for custom shop Les Pauls. Even though, i put those on my BB.
