Bought these for my HB guitar, mostly for looks. They are larger than the ones that came as standard on my HB, but after 15min with a bridge pin reamer they fitted PERFECTLY. After installing these I was surprised that the sound quality actually was noticeable better (I didn't change my strings or anything else). I'm not sure if it's because of the better material than the stock plastic ones or because they fit better than those which where on my guitar.
In conclusion, they feel premium, look great, sound awesome and probably will last forever, therefore, they are well worth it!
