Ibanez RG450QMB-SPB

Technical review: Ibanez RG450QMB-SPB

The Ibanez RG450QMB-SPB is a blue, solid-body electric guitar with an HSH pickup layout, a 24-fret neck, and an Edge-Zero II tremolo. Its specifications describe a familiar combination of two humbuckers and a middle single-coil pickup, paired with a locking nut and a 25.5-inch scale. The instrument has been available since May 2025. The listed price is 527, with no currency specified in the supplied information.

This is a specification-based assessment. No customer reviews are available, so there is no basis for claims about comfort, tuning stability in use, sound quality, or build consistency. Those qualities would need to be checked on an individual instrument.

Body, top, and finish

The body is made from meranti, with a quilted maple top. The listed finish is Sapphire Blue, and the hardware is black. These details identify the guitar's materials and appearance, but do not establish the thickness of the top, the body's weight, or how the finish looks under different lighting. Those points are not included in the specifications.

There is no stated body contour, body thickness, or weight. Buyers who need a particular balance while standing, or who prefer a specific body shape, should verify those details directly rather than infer them from the model name or photographs.

Neck and fingerboard dimensions

The bolt-on neck is maple, and the fingerboard is jatoba with white dot inlays. Ibanez lists a Wizard III neck profile, a 400 mm fingerboard radius, and a nut width of 43 mm. The scale length is 648 mm, also given as 25.5 inches. Together, these figures provide a useful dimensional outline, although they cannot convey how the neck will feel in a player's hands.

The fingerboard has 24 jumbo frets. That fret count gives access to two full octaves on each string, while the jumbo size describes the frets' relative category, not their precise height or width. The available information does not specify fret material, neck thickness, or the dimensions of the profile at particular fret positions.

Pickup layout and controls

The pickup set consists of two Quantum humbuckers, at the neck and bridge positions, plus a Quantum single-coil pickup in the middle. This HSH arrangement combines two pickup types in one instrument. A five-way switch selects among pickup combinations, while the controls are limited to one volume knob and one tone knob in the published specifications.

The listed pickup names and positions are useful for identifying the configuration, but they do not provide electrical measurements or describe the output and tonal response. The specifications also do not explain the wiring of each switch position. Players who need a particular split-coil setting or switching arrangement should confirm the circuit details before purchase.

Tremolo and tuning hardware

The guitar uses an Edge-Zero II tremolo and a locking nut. Ibanez machine heads are also listed. This hardware combination is relevant to players considering a guitar with a tremolo system, but the parts list alone cannot establish how well the instrument holds tune, how the bridge responds, or how much setup work it may require. No details are provided about the included tools, adjustment instructions, or replacement parts.

There is no gig bag or case included. Buyers should account for a separate purchase if they need protection for transport or storage. The specifications identify the hardware color as black, but do not give further details about its finish or construction.

What the specifications establish

• Body: Meranti with a quilted maple top, finished in Sapphire Blue.
• Neck: Bolt-on maple neck with a Wizard III profile and jatoba fingerboard.
• Fingerboard details: 400 mm radius, white dot inlays, 24 jumbo frets, and a 43 mm nut width.
• Electronics: Two Quantum humbuckers, one Quantum single-coil pickup, volume and tone controls, and a five-way switch.
• Bridge hardware: Edge-Zero II tremolo, locking nut, and Ibanez machine heads.
• Included protection: No bag or case.

Bottom line

The RG450QMB-SPB's published specification presents a 24-fret, 25.5-inch guitar with an HSH pickup layout, a locking nut, and an Edge-Zero II tremolo. Its materials, neck dimensions, controls, and included accessories are clearly identified. The available data does not support conclusions about sound, setup, playing comfort, or real-world tuning performance. A hands-on inspection is the sensible next step for anyone weighing those factors, especially because no customer feedback is available.
