A precision Tune-O-Matic replacement built specifically for the smaller 4mm bridge post size used on Epiphone and other import guitars before their recent hardware revisions.

2 guitars checked: 1 likely drop-in, 1 not compatible.

For your Epiphone Casino (2023+)

Not compatible

A well known Casino upgrade, but it is sized for the older, smaller 4mm bridge posts. Owner measurements show 2023 and later Casinos have larger 6mm posts, so this bridge will not fit them. Look for a bridge built for the larger post size instead.

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

Why we say this

A well regarded Casino bridge upgrade, but it is built for the 4mm post size used before the 2023 hardware change. An owner who measured a 2023 Casino reports 6mm posts, so this bridge will not fit them. That is a single owner measurement, though it fits with 4mm posts reported on a 2021 Casino Worn. Most existing Casino buying guides still point to this bridge without noting the hardware split.
