The Epiphone SG Standard uses a LockTone Tune-O-Matic bridge and LockTone Stop Bar tailpiece with Grover Rotomatic tuners at an 18:1 ratio. One detailed measurement source puts the tuner holes at 10mm, bridge post spacing at 74mm and string spacing at 52mm, consistent with the modern Epiphone standard, though not yet confirmed against an official spec sheet. Fretboard is laurel on most colourways, though rosewood appears on at least one Epiphone-listed finish. ProBucker 2 and 3 pickups sit in a standard humbucker route.

Purpose-built for this bridge style. Locking studs mean it won't fall out when you change strings.
TonePros markets the NVR2 specifically as their Nashville-spec locking retrofit. Consistently reported as a straightforward install in Epiphone-specific threads, including on current-production SG models.

Should fit, but post spacing on Epiphone Nashville-style bridges varies slightly by year and model. Measure your studs before buying if you want a guaranteed fit.
StewMac lists Gotoh's drop-in Nashville replacement at 73.99mm post spacing, but multiple owner caliper measurements on Epiphone LPs range from 73.0mm to 74.4mm depending on model year. This guitar's own bridge post spacing (74mm) comes from a single detailed measurement source, not yet cross-checked against an official spec sheet.

View at AmazonThis swaps only the saddles, so you keep your existing bridge. Graph Tech sell different saddle sets for different bridge stamps though, so check the stamp on the underside of your bridge and order the matching one.
Graph Tech match their TUSQ saddle sets to the stamp on the underside of the bridge rather than selling one universal set, and their own fitment guide lists a distinct SKU per stamp. The Epiphone-spec set, PQ-8633-00, is the correct SKU for a modern Epiphone-style import Tune-o-matic, which is the bridge style on this guitar. What has not been independently confirmed is the exact stamp on this particular model, and that is the detail that decides which set to order.

This bridge is built for genuine Gibson Nashville posts, not Epiphone's. You'll need to swap in Faber's own conversion posts first, no drilling required if you use their simplest kit.
Faber's own FAQ states Epiphone and other imported guitars use bridge posts that screw into bushings, not original Nashville inserts, and require Faber conversion bridge studs (NSWKIT, BSWKIT, or iNsert) to use any Faber bridge including the ABRN. NSWKIT is a straightforward stud swap with no drilling. BSWKIT is more invasive, needs the body inserts removed and tapped. The plain ABRN alone is not a drop-in for this guitar.

Fits the standard humbucker route like this guitar's other pickup options. This set leans toward a mellower, more vintage-voiced tone rather than higher output.
Same route and mounting as the Pearly Gates set. Also a commonly recommended Epi swap, leans toward a mellower, more vintage-voiced tone rather than higher output.

This is literally what Gibson ships in its own USA SG Standard; a genuine drop-in for the Epiphone's standard humbucker route, not just a similarly-sized third-party part.

This tuner is sized for vintage tuner holes, not the modern holes on this guitar. You'll need Gotoh's conversion bushings, sold separately, to fit it.
This tuner is vintage-hole spec (8.73 to 8.8mm), not the modern 10mm hole this guitar actually has. Gotoh sells conversion bushings separately for exactly this situation. Not a direct swap, but not a drilling job either, it is a bushing change.

A real modification, not a drop-in. New holes go in the guitar, best left to someone experienced or a tech.
This guitar ships with a fixed LockTone Stop Bar, not a vibrato. Direct-mounting a Bigsby means new holes in the top.
