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.
