There are three different types of Master Kits available for your Gibson guitar with a “Tune-O-Matic” Bridge. The type you need is determined upon how the bridge mounts on your guitar. Inspect these images to see which type you have.
Please note: Because Gibson USA/ABR-1 and Nashville bushing mounted posts do not have threads on the upper bridge posts, Faber® conversion bridge posts are required to mount the Tone-Lock® Bridge included in all Faber® Master Kits. Gibson ABR-1 with Direct Mounted Posts (Vintage/Custom Shop/1990-2003 LP Classic) do not require conversion posts.
