Ibanez RG421S-SEM

Ibanez RG421S-SEM review

The Ibanez RG421S-SEM is a solid-body electric guitar in the RG Series, listed as available since June 2024. Its specification centers on a meranti body, a bolt-on maple neck with a Wizard III profile, a jatoba fingerboard, and two Quantum humbuckers. The guitar has a fixed F106 bridge rather than a tremolo system, and its listed price is 372. No customer reviews are available, so this assessment is based only on the supplied product details.

The finish is named Sea Shore Matte, with a matte polyurethane finish on the neck and body. The general color listing says blue. No separate top wood is specified. Hardware is finished in Cosmo Black, and the fingerboard has white dot inlays. These details describe the instrument's materials and appearance, but they do not establish how the finish or hardware will wear over time.

Neck, fingerboard, and scale

The maple neck is attached with a bolt-on joint and uses Ibanez's Wizard III profile. The fingerboard is jatoba, with a 15.75-inch radius and 24 jumbo frets. The scale length is 648 mm, also given as 25.5 inches, while the nut measures 43 mm, or 1.7 inches, across. The nut is plastic.

Those measurements give a clear sense of the layout without requiring assumptions about feel. The 25.5-inch scale is the stated measurement, while the wide-radius fingerboard and jumbo fret specification identify the neck's basic geometry. Players comparing guitars should still try the neck shape and fret dimensions in person when possible, since the specification alone cannot say whether they will suit a particular playing style.

The 24-fret layout provides two octaves on each string, subject to the guitar's tuning and setup. The provided information does not give fretboard edge treatment, fret material, neck thickness measurements, or factory action. It also does not state whether the neck includes a particular reinforcement rod or describe its adjustment range.

Pickups and controls

The RG421S-SEM has two passive Quantum humbuckers in an HH configuration. Its controls consist of one volume control, one tone control, and a five-way switch. This gives the player several selectable pickup combinations, but the supplied specifications do not map the switch positions to specific coil or pickup arrangements. They also do not provide output measurements, magnet details, or a fuller description of the pickups' tonal response.

That distinction matters when judging an instrument from a specification sheet. The presence of two humbuckers and a five-way switch confirms the pickup and control layout, but it is not enough to make reliable claims about output, noise level, or how the guitar will sound through a particular amplifier. The electronics are passive, with no battery-powered preamp listed.

Bridge, tuning hardware, and included items

The F106 bridge is a fixed design, and the product specifications state that the guitar has no tremolo. Players who want a bridge that moves for pitch effects should account for that before buying. Conversely, the fixed-bridge configuration keeps the listed hardware straightforward, though the available information does not specify the bridge's saddle adjustment range or construction materials.

Ibanez machine heads are fitted, and the supplied string set is D'Addario EXL110, with gauges of.010,.013,.017,.026,.036, and.046. Neither a bag nor a case is included. The data does not specify whether the guitar ships with any additional accessories or describe its setup at delivery.

What the specifications establish

The clearest strengths on paper are the defined RG layout, 24 jumbo frets, a conventional 25.5-inch scale, two passive humbuckers, and a fixed bridge. The maple neck, jatoba fingerboard, and meranti body provide a specific material combination, while the matte polyurethane finish and dark hardware give the model a distinct visual description. These are verifiable features, not evidence of a particular sound, comfort level, or long-term reliability.

At a listed price of 372, the RG421S-SEM can be compared with other guitars by checking whether they offer similar fret count, pickup configuration, scale length, and bridge type. The price alone does not establish value, especially without details about regional pricing, setup, warranty, or competing models. Item number 582063 identifies the listing, and the sales unit is one guitar.

Verdict

The Ibanez RG421S-SEM is specified as a 24-fret, dual-humbucker electric guitar with a maple Wizard III neck and fixed F106 bridge. Its listed details are substantial enough to assess its basic layout and hardware choices, but not to predict its sound or playing feel. There are no customer reports to add practical experience, and the supplied data leaves several setup and construction questions unanswered. Buyers should verify the exact finish, included accessories, price, and preferred neck feel with the seller before ordering.
