Ibanez S6621AH-TGB: a specification-based review

The Ibanez S6621AH-TGB is a Japanese-made, solid-body electric guitar with a mahogany body, an ash top, and two DiMarzio humbuckers. Its specification sheet points to a focused design: a thin neck profile, 24 jumbo frets, a fixed bridge, and locking machine heads. This review assesses those listed features rather than reporting playing impressions. No customer reviews are available for this product.

The guitar has been available since April 2026. Its listed price is 2055, with no currency stated in the supplied information. The finish is Transparent Gray Burst with a high-gloss surface, and the hardware is Cosmo black. A case is included; a separate gig bag is not.

Body, top, and neck construction

The body is mahogany, topped with ash. These woods are explicitly identified in the specifications, although no weight, body measurements, or tonal test results are provided. The gray burst finish leaves the wood combination as part of the instrument's visual description, but the available information does not specify the top's grain or whether the ash is a thick cap or a veneer.

The neck uses a five-piece maple and walnut construction and attaches to the body with bolts. Its Super Wizard HP profile measures 17 mm thick at the first fret and 19 mm at the twelfth. Those dimensions provide a more useful description than the profile name alone: the neck remains slim across the measured points. Individual hand comfort will still depend on preference and playing style, and cannot be established from measurements alone.

The rosewood fingerboard has white offset dot inlays and a 430 mm radius, equivalent to 16.93 inches. The relatively flat radius is a clear design specification, not proof of a particular setup or playing result. Nut width is 43 mm, or 1.69 inches. The nut is a Graph Tech Black TUSQ XL component.

Frets, scale, and tuning hardware

The instrument has 24 jumbo frets and a 648 mm (25.51-inch) scale length. This is a full-length scale, and the two-octave fretboard provides access to 24 fret positions. The fret material, fret-end treatment, and factory action are not listed, so those details should be checked on the individual guitar rather than assumed.

At the bridge, Ibanez specifies a Gibraltar Standard III fixed bridge. There is no tremolo system. That makes this model distinct from guitars designed for pitch changes using a movable bridge, but the listed information does not establish how the bridge feels under the picking hand or how the instrument performs during tuning tests.

Gotoh MG-T locking machine heads are fitted, and the listed strings are D'Addario EXL110. Locking tuners can make string changes more direct by securing the string at the tuning post. They do not remove the need for correct winding, stretching, or a stable nut and bridge setup. The supplied Graph Tech nut and fixed bridge are relevant parts of that overall setup, but no tuning-stability measurements are available.

Pickups and controls

The pickup layout is HH: one DiMarzio The Tone Zone humbucker at the bridge and one DiMarzio Air Norton humbucker at the neck. Controls consist of one volume knob, one tone knob, and a five-way selector. The pickup models and switching format are stated, but the precise wiring combinations for each selector position are not. The specifications therefore do not support claims about coil splitting or any particular switching function.

For a buyer comparing configurations, the main distinction is the two-humbucker layout paired with a five-way switch, rather than a traditional three-way selector. Confirm the switching diagram with Ibanez or the retailer if specific pickup combinations are important. No output measurements, frequency response, or recorded sound examples are included in the supplied data.

What the specifications establish

The S6621AH-TGB has a coherent hardware and construction brief: a bolt-on five-piece neck, a fixed bridge, locking tuners, two named DiMarzio humbuckers, and a high-gloss gray burst finish. The 24 jumbo frets, 648 mm scale, and 43 mm nut width give concrete reference points for comparing its dimensions with other guitars. Its included case is useful to note when calculating the purchase package; the listing does not include a gig bag.

The limits of the available information matter. There are no customer reviews, and the supplied specifications do not report weight, setup quality, production tolerances, or measured acoustic and amplified performance. The listed features make the Ibanez S6621AH-TGB straightforward to assess on paper, but a buyer should inspect the instrument or confirm setup details with the seller before purchase.
