The Epiphone G-400 SG is a classic double-cutaway electric based on the legendary SG formula, combining a lightweight mahogany body, set mahogany neck and dual-humbucker electronics with the excellent upper-fret access that has made the design a rock favourite for generations.

This particular example comes from Epiphone’s Korean production era, a period that has developed a strong following among players looking for older G-400 models with traditional construction and straightforward passive electronics.

The G-400 uses a mahogany body, set mahogany neck, rosewood fingerboard and 24.75" scale length, together with a pair of humbuckers and the familiar two Volume, two Tone and 3-way selector layout.

This Pre-Owned example is in Good condition, however, there is a small indentation on the body, above the bridge pick-up.

WHY YOU’LL LOVE IT

The G-400 delivers the essential SG experience without moving into Gibson pricing.

Its thin mahogany body keeps the guitar relatively manageable, while the set neck and dual-humbucker layout provide the full-bodied sustain and midrange that suit rock and blues particularly well.

The Korean manufacture gives this example additional appeal to players who specifically seek out older Epiphone instruments.

DETAILED FEATURES & BENEFITS

Classic SG Body

The G-400 follows the familiar SG double-cutaway format.

Deep horns provide excellent access to the upper register, making the guitar particularly comfortable for lead playing.

Mahogany Body

The mahogany body contributes warmth, sustain and a strong midrange response.

It gives the G-400 the tonal foundation expected from an SG-style guitar.

Set Mahogany Neck

The mahogany neck is glued into the body using set-neck construction rather than a bolt-on joint.

This provides a smooth transition into the body and gives the guitar a more traditional SG-style construction.

Rosewood Fingerboard

The rosewood fingerboard provides a smooth and familiar playing surface.

Korean G-400 examples can feature either dot or trapezoid inlays depending on production period, so the exact inlay style has not been assumed here.

24.75" Scale Length

The traditional 24.75" scale length gives the strings a slightly softer feel than a Fender-style 25.5" scale.

This makes bends comfortable and contributes to the familiar Gibson-style playing response.

22 Frets

The G-400 uses 22 frets, combined with deep body cutaways for excellent access to the highest positions.

Dual Humbuckers

The traditional HH pickup configuration provides warm, powerful tones with lower noise than conventional single coils.

The bridge pickup delivers greater attack and bite, while the neck pickup provides warmer and smoother sounds.

Traditional Four-Control Layout

The guitar uses:

• Neck Volume

• Bridge Volume

• Neck Tone

• Bridge Tone

This allows each pickup to be adjusted independently.

Three-Way Pickup Selector

The 3-way toggle provides:

• Neck pickup

• Both pickups

• Bridge pickup

Tune-O-Matic & Stopbar

The Tune-O-Matic-style bridge allows individual string intonation adjustment, while the fixed stopbar tailpiece provides secure string anchoring.

HOW IT COMPARES

G-400 vs Gibson SG Standard

The G-400 follows the same broad formula of a mahogany double-cutaway body, set mahogany neck and dual humbuckers.

The Epiphone provides that familiar feel and layout at a significantly more accessible price point.

G-400 vs G-310

The G-400 traditionally sits above the more basic G-310 in Epiphone’s SG range.

One of the biggest structural differences is the set mahogany neck used on the G-400 rather than the more budget-oriented construction associated with many G-310 versions.

Korean G-400 vs Later Production

Epiphone has manufactured the G-400 in several factories and countries over its lifespan.

Older Korean examples have developed a particular following among players interested in Epiphone’s 1990s and early-2000s production.

FAIR DEAL MUSIC EXPERT VERDICT ★★★★★

Best suited for: Players looking for a traditional SG-style guitar with set-neck construction and the additional appeal of Korean Epiphone manufacture.

Customers usually upgrade from: Starter electric guitars, Epiphone G-310 models and entry-level dual-humbucker instruments.

Most commonly paired with: Valve amplifiers, overdrive, distortion, boost, delay and reverb.

Our tip: Korean G-400s vary slightly depending on production year, so the individual guitar matters more than chasing one generic specification. A serial number can help narrow down exactly when and where this example was produced.

Showroom feedback: The G-400 remains one of Epiphone’s most successful SG-style designs. The thin mahogany body, set neck and straightforward humbucker layout make it a very usable rock guitar, while Korean-made examples have an additional following of their own.
