    Casino 2020

    Likely drop-in

    Built for the smaller bridge posts this guitar actually uses, a well known upgrade for this exact Casino era.

    Why we say this

    This bridge is explicitly built for the 4mm bridge posts used on Epiphone and other import guitars before their recent hardware revisions. The 2020 and pre-2023 Casino is the exact pre-revision guitar that describes. Epiphone changed the Casino's bridge posts from 4mm to 6mm during 2023, so the two generations take genuinely different bridges, and this one is built for the earlier, narrower posts.

    Not compatible

    Epiphone

    Casino (2023+) 2023

    This is a well known Casino upgrade, but it is sized for the older, smaller bridge posts. This guitar has the newer, larger posts, so this specific bridge will not fit. See this guitar's other bridge option built for the larger post size instead.

    Why we say this

    This is a real, well regarded Casino bridge upgrade, but it is built for the smaller 4mm post size used before the 2023 hardware change. This guitar's posts measure 6mm, so this specific bridge will not fit. This is exactly the kind of generation mismatch worth flagging, most existing Casino buying guides still point to this bridge without noting the hardware split.
