Gretsch 6134CST 55 Penguin GS Relic review

The Gretsch 6134CST 55 Penguin GS Relic is a U.S.-made Custom Shop electric guitar with a single-cut body, a chambered mahogany body structure, and a green sparkle top. Its specifications combine mahogany for the body and neck, a maple top, an ebony fingerboard, two DynaSonic humbucking pickups, and Bigsby-style vibrato hardware. The listed finish is relic, with white on the back and sides and green sparkle on the top.

This assessment is based strictly on the supplied product information. No customer reviews are available, so there is no basis for claims about playing feel, sound quality, setup, or build consistency in individual examples. The listed price is 7,333, and the model is identified as a single-piece limited run, a detail that distinguishes this particular offering from a regular production specification.

Construction and finish

The chambered body is made of mahogany, with a maple top. The neck is also mahogany, while the fingerboard is ebony. The product listing does not state the chamber layout, body dimensions, neck profile, neck joint details, or finish thickness. Those omissions matter to buyers comparing ergonomics or construction methods, and they should not be filled in by assumption.

The finish combines green sparkle on the top with white on the back and sides. Gold sparkle binding, a gold pickguard, and gold hardware give the instrument a coordinated decorative scheme. Gretsch specifies nitrocellulose lacquer and a relic finish, but does not describe the aging treatment or the amount of simulated wear. The finish name therefore identifies a style, not a documented account of how much distressing appears on this individual guitar.

Fingerboard details include Hump Top Plain inlays and 22 medium frets. The headstock carries a vertical "Wing" logo. The scale length is 625 mm, also listed as 24.6 inches, and the nut width is 43 mm. These measurements provide useful reference points, although the available data does not include fretboard radius, fret dimensions, or neck depth.

Pickups and hardware

The pickup configuration is HH, with two DynaSonic humbuckers. That identifies the pickup type and layout, but the listing gives no output measurements, magnet details, switching arrangement, or control specifications. As a result, the available information cannot establish the guitar's tonal range or how its controls are wired.

A Bigsby B3G tremolo is paired with a Bigsby Compensated bridge. This confirms the named vibrato and bridge components, but the supplied data does not specify the bridge material, saddle adjustment range, or string spacing. Grover Imperial machine heads are fitted, and the hardware is listed as gold. The combination is clearly part of the instrument's visual design, though performance claims about tuning stability would require direct testing.

• Body: chambered mahogany with a maple top
• Neck: mahogany, with an ebony fingerboard
• Fingerboard: 22 medium frets and Hump Top Plain inlays
• Scale length: 625 mm, or 24.6 inches
• Pickups: two DynaSonic humbuckers
• Vibrato and bridge: Bigsby B3G and Bigsby Compensated bridge

Practical details and buying context

The guitar includes a case and a certificate. No gig bag is included. It is listed as available since October 2025, under item number 521071, and the sales unit is one piece. The product is made in the USA. The listed color is green, with the more detailed finish description clarifying that the top is green sparkle and the back and sides are white.

The single-piece limited-run designation calls for careful consideration before purchase. Buyers should confirm the current availability, exact condition, and what the certificate documents, especially because the listing identifies a relic finish and specifies one piece rather than a continuing run. The price is substantial, so details such as the setup, included case type, and any specific finish marks are reasonable points to verify with the seller. The supplied specifications do not answer those questions.

Verdict

On paper, the Gretsch 6134CST 55 Penguin GS Relic is a distinctive Custom Shop instrument with a clearly defined material and hardware package. Its chambered mahogany body, maple top, ebony fingerboard, DynaSonic humbuckers, Bigsby system, and gold appointments are documented features. The green sparkle and white finish, relic treatment, and single-piece limited-run status shape its identity as much as its core construction does.

The specification sheet is not enough to judge its sound, comfort, tuning behavior, or execution in person. With no customer reviews available, those points remain unverified. A prospective buyer can use the listed materials and measurements to assess whether the design fits their needs, but should seek instrument-specific details before committing to the 7,333 price.
