This is an ABR-1 bridge made by the famous Kluson, with nickel plating and wired. It has brass saddles that are not plated. This is a new bridge that has been modified with flat-head saddles and pre-grooved, so it's ready to use immediately and will last for a long time. It's an inch standard, so it's Gibson compatible. About Flat-Head Saddles: These saddles were used from around the time the ABR-1 became wired until the Nashville bridge was introduced. Because the contact area between the strings and the saddle increases compared to sharp-head saddles, the high frequencies are suppressed, so when used on a Flying V or Firebird, the unpleasant high frequencies disappear, and the sound becomes thicker and sweeter. Recommended for those aiming for a 60s-70s sound on a Les Paul or SG. If you're not satisfied with just replacing your pickups, please try paying attention to the bridge and saddles. You'll notice a significant change♪ Vintage Maniacs has previously published a feature article on this, which is also interesting, so please take a look.
