Ibanez S6670SK Prestige Dark Ultramarine Review: Premium HSH Japanese Craft

Who Should Buy It

Key Specifications

Overview

The Ibanez S6670SK Prestige Dark Ultramarine occupies the premium tier in Ibanez's S-series line. The listing highlights a Japanese build, an African Mahogany body, a Silky Oak top and a Super Wizard HP neck. It is part of the Prestige range, which traditionally signals higher attention to materials and assembly. On paper, the instrument aims to deliver a fast playing experience with a broad HSH pickup set.

This premium instrument is listed with both Dark Ultramarine Blue and Sunset Burst finishes, and the included hardshell case adds transport protection. The overall feature set centers on a Lo-Pro Edge tremolo, DiMarzio Tone Zone bridge pickup and cosmo black hardware. Some core specifications are not published, so this review works only with the details the listing provides. Because this is a research review, no in-person claims are made.

Body, Neck and Playability

The published body specification pairs an African Mahogany back with a Silky Oak top. Mahogany is generally associated with warm midrange and sustain, while a top wood can add clarity, but the listing does not provide weight or thickness. The Silky Oak top is not a common reference point for many bass players, so its exact contribution remains somewhat uncertain. Buyers should treat the tone description as a general indication rather than a measured result.

The neck is listed as a Super Wizard HP 5 piece Maple/Walnut design with a bound Rosewood fretboard and off-set white dot inlays. The Super Wizard HP name suggests a thin profile intended for rapid navigation, though exact nut width, radius and fret count are not published. The bound Rosewood fretboard is a familiar premium feature that may feel smooth under the fingers. Without playing it, the playability picture is promising but incomplete.

Because the listing does not state scale length or string count, ergonomic expectations are harder to pin down. The product type mentions bass guitar, while the HSH and tremolo specs are more common on an electric guitar. This mismatch should push buyers to confirm these details before purchase. The available build details still suggest a carefully assembled Japanese instrument.

Pickups and Tone

The HSH pickup configuration is one of the most important sonic features in the listing. It places a humbucker at the bridge, a single coil in the middle, and another humbucker at the neck. Only the bridge pickup is named: a DiMarzio The Tone Zone humbucker. That pickup is generally known for a thick and powerful character, but the listing does not include output specs or the neck and middle models.

The DiMarzio Tone Zone bridge humbucker gives the S6670SK a high output anchor for distorted leads and heavy rhythm. The single coil middle position should offer a brighter and cleaner voice, but the exact model is not published. The neck humbucker remains unidentified as well, so the overall balance between positions is only partly understood.

African Mahogany and Silky Oak may add warmth and sustain, based on common wood behavior, but the listing does not quantify these effects. The Lo-Pro Edge bridge is also part of the tonal equation, as a double locking tremolo can influence resonance and sustain. Without published frequency response or output specs, the review can only describe the general sonic direction implied by the components.

Hardware and Electronics

The most prominent hardware item is the Lo-Pro Edge tremolo bridge. This double locking design is intended to hold tuning during aggressive whammy use, and its lower profile can be comfortable for picking hand placement. The listing does not specify the block material or included tremolo arm, but the bridge name carries a known performance reputation.

The electronics are only partially documented. The bridge humbucker is named, but there are no published details for the middle and neck pickups, control layout, switching options or active/passive circuit. Cosmo black hardware appears across the visible metal parts and contributes to the dark blue color scheme. The included hardshell case is a practical addition for storage and transport.

Build Quality and Finish

Ibanez builds this S6670SK in Japan, which aligns with the Prestige series reputation for professional grade assembly. Japanese manufacturing in this range often implies tight neck joints, clean fretwork and careful finish application, but this particular listing does not provide close-up inspection details. The African Mahogany and Silky Oak pairing gives the instrument a distinctive visual and material spec.

The Dark Ultramarine Blue finish is the focus here, and the cosmo black hardware offers a modern contrast against the deep blue body. The listing also mentions a Sunset Burst option, but this review centers on the Dark Ultramarine Blue preferred name. Without in-person inspection, finish consistency and fret end quality remain unverified.

The bound Rosewood fretboard and off-set white dot inlays are tasteful details that suggest attention to visual design. The off-set dot placement is a modern Ibanez cue that some players prefer over standard center dots. The hardshell case included in the package adds another layer of perceived build confidence, though it does not change the instrument itself.

Setup Out of the Box

Factory setup details are absent from the listing, including string action, neck relief and intonation. A Lo-Pro Edge tremolo requires careful balancing, and a fresh import or shipping can affect setup. Buyers should expect that a premium instrument may need minor adjustments after temperature changes.

A double locking tremolo adds setup complexity compared to a fixed bridge, especially for players unfamiliar with floating tremolo systems. The included case helps protect the instrument during shipping, but does not eliminate the need for a setup check. Because this is a research review, there is no in-person measurement of the setup from the box.

The Super Wizard HP neck may arrive with acceptable playability, but the exact string height and relief tolerances are not published. A qualified tech can set the instrument to individual preferences once the missing string gauge and tuning are known. Buyers who are not comfortable with tremolo upkeep should factor that learning curve into the purchase.

Daily Use and Practice

For daily practice, the Super Wizard HP neck and bound Rosewood fretboard are the key playability features. The listing suggests smooth and rapid fret navigation, which suits practice sessions focused on technique. The body shape is not fully described beyond wood, but the S-series is generally associated with a slim and contoured silhouette in the broader Ibanez catalog.

The Lo-Pro Edge bridge is both an expressive tool and a maintenance responsibility. String changes on a double locking tremolo take more time than on a fixed bridge, and tuning adjustments involve the locking nut and bridge fine tuners. The included hardshell case makes it easier to store the instrument safely between practice sessions.

The HSH pickup set should keep practice interesting, allowing players to move from clean single coil sounds to thicker humbucker tones. The missing control details mean a buyer will need to review the actual switch and knob layout before relying on specific practice presets. Overall, the listed components suggest a player-friendly instrument for frequent use, with some tremolo upkeep expected.

Versatility and Styles

On paper, the HSH pickup configuration supports a wide range of musical styles. It can cover jazz, blues, rock, metal and fusion, depending on the player's amp and control settings. The DiMarzio Tone Zone bridge humbucker is typically associated with high output rock and metal, but the listing does not publish output resistance or EQ curves.

The Lo-Pro Edge tremolo extends the expressive range through vibrato and pitch effects, useful for lead playing and modern styles. The African Mahogany and Silky Oak body may add warmth that balances brighter single coil positions, though the exact balance is not documented. The instrument should adapt to a variety of genres if the control layout offers enough switching.

The missing scale length and string details limit a complete prediction for different playing styles. If the product type is a bass, the HSH and tremolo specs are atypical, so players should confirm the actual format. The listed versatility is promising, but the full picture depends on the unknown details.

Who Should Buy It

This model suits players who want a premium Japanese build with a fast neck and HSH tonal range. The listed DiMarzio bridge humbucker and Lo-Pro Edge tremolo will appeal to those who like modern hardware and expressive vibrato. The included hardshell case adds practical value for anyone who transports gear regularly.

Buyers who trust Ibanez Prestige build quality and are comfortable with tremolo systems should find the S6670SK appealing. The Dark Ultramarine Blue finish is a standout visual choice, while the Sunset Burst offers a warmer alternative. The listing's premium tier means this is not a casual starter instrument.

Players who prioritize complete published specs may be frustrated by the missing scale length, string details and control layout. The review can only recommend the instrument on the strength of the specs that are present. If the unspecified details are confirmed elsewhere, the buying case becomes much stronger.

Verdict

The Ibanez S6670SK Prestige Dark Ultramarine makes a strong on paper case with Japanese build, African Mahogany body, Silky Oak top and a Super Wizard HP neck. The HSH set with DiMarzio Tone Zone bridge humbucker, Lo-Pro Edge tremolo and included hardshell case are premium features.

The main limitation is missing published specification for scale length, string count, controls and some pickup models. This review cannot verify exact fit or bass specific details. Score 88 because the listed parts are high quality, but buyers should confirm the unknown specs before purchase.
