Flathead saddles for ABR-1 bridges. Made of brass, pre-grooved. Flat saddles were also used on Jimmy Page's Les Paul, and this product is a prototype made when creating a Jimmy Page-spec TOKAI Les Paul, which is known as a Japanese vintage guitar. Therefore, it is a metric size. About Flathead Saddles These saddles were used from around the time ABR-1 became wired until the Nashville bridge was adopted. Compared to sharp heads (left in photo 3), the contact area between the strings and the saddle increases, suppressing the high frequencies, so when installed on a Flying V or Firebird, the unpleasant high frequencies disappear, and the sound becomes thicker and sweeter. Vintage Maniacs previously published a feature article, which is also interesting. ⚠️The Gibson bridge in the photo is not included. #gibson #fender #PRS #Epiphone #zemaitis #ESP #Gretsch #Rickenbacker #Suhr #tokai #Fernandes #Fujigen #Greco #electricguitar #guitarrepair #guitarparts #guitarcraft
