Ibanez RGRB720-BKF: a specification-led review

The Ibanez RGRB720-BKF is a black, solid-body electric guitar listed at $899 and available since March 2025. Its specification centers on a 648 mm scale, 24 jumbo frets, two DiMarzio D Activator 7 humbuckers, and an Edge-Zero tremolo. Those details describe a guitar built around seven-string hardware and pickup models, although the supplied data does not state the string count directly. This review is therefore limited to the published specifications, rather than playing impressions or customer feedback.

There are no customer reviews available for this product. The information below explains what its listed components indicate, without treating expected behavior as a verified result. One specification conflict also needs attention: the general listing names an ebony fingerboard, while the detailed description says rosewood. The supplied data does not establish which material is fitted, so that point should be confirmed with the seller before purchase.

Body, neck, and playing dimensions

The body is made from nyatoh, with no separate top listed. Its finish is described as black flat matte, and the neck has a matte polyurethane finish. Polyurethane is also specified as the overall lacquer type. These facts identify the construction and surface treatment, but they do not establish the instrument's weight, balance, acoustic response, or resistance to wear.

The three-piece maple neck is bolt-on and uses Ibanez's Wizard II profile. Its listed thickness at the first fret is 19 mm. The scale length is 648 mm, or 25.5 inches, and the nut width is 48 mm. Together, these measurements give buyers concrete dimensions to compare against another guitar. They do not, on their own, determine whether the neck will feel comfortable in a particular player's hands.

The fingerboard radius is 400 mm, equivalent to 15.75 inches, and the guitar has 24 jumbo frets. A 24-fret layout provides two octaves of frets per string, subject to the instrument's tuning and string count. The locking nut works with the tremolo system, while luminescent side-dot inlays are intended to make the fretboard's side markers visible in low light. The specification does not describe fret finishing, setup, or the brightness of those markers.

Pickups and switching

Ibanez lists two DiMarzio D Activator 7 humbuckers, one at the neck and one at the bridge. The model name identifies the specified pickup family, while the "7" designation aligns with the product's seven-string-oriented components. The provided information does not give output measurements, magnet type, or a switching chart, so detailed claims about tonal character or available coil combinations would go beyond the evidence.

Controls include separate volume and tone knobs, a five-way switch, and the dyna-MIX10 switching system with an Alter Switch. The system name suggests multiple pickup configurations, but the supplied data does not explain what each switch position produces. Buyers who need particular combinations, such as a split-coil setting or a specific output, should check the official wiring diagram or ask the retailer for the switching chart rather than assume a configuration.

Tremolo and tuning hardware

The Edge-Zero tremolo is paired with a locking nut, and Gotoh machine heads are also listed. This is a more involved setup than a fixed bridge: the bridge can move, while the locking nut clamps the strings at the neck end. The specification confirms those parts, but does not state whether the tremolo is set up for floating use, how its springs are configured, or how easy it is to adjust. Routine string changes and tuning adjustments may require familiarity with a locking tremolo system.

The included-accessory fields say that neither a case nor a gig bag is included. At the listed $899 price, buyers should account for separate protection during storage and transport. The sales unit is one piece, and the item number is 606992.

What the specifications support

The RGRB720-BKF has a defined hardware package: a maple bolt-on neck, 24 jumbo frets, two specified humbuckers, a multi-position switching system, and an Edge-Zero tremolo with a locking nut. Its dimensions and control names are useful for comparison, but the data leaves several practical questions unanswered, including the fingerboard material conflict, the exact switching functions, the setup, and the included case status beyond the explicit no-case and no-gig-bag entries.

In short, the published information supports a careful feature comparison, not a verdict on sound, comfort, tuning stability, or factory setup. There are no customer reviews available to add firsthand evidence. Confirm the fingerboard material and obtain the switching chart before ordering if either detail affects your decision.
