Ibanez RG5121RL-DBF review: specifications and design

The Ibanez RG5121RL-DBF is a left-handed, six-string electric guitar with a fixed bridge and two Fishman Fluence Modern Ceramic humbuckers. Its listed price is $1,999, and it has been available since March 2026. The specifications describe a focused RG-style setup: a 648 mm scale, 24 jumbo stainless-steel frets, a bolt-on maple and wenge neck, and a Gibraltar Standard III bridge.

This is an assessment of the published specifications, not a report from playing the guitar. No customer reviews are available, so claims about comfort, sound quality, tuning stability, or build consistency would be premature. The details below explain what the listed components indicate and what a prospective buyer should verify in person where possible.

Body, finish, and left-handed layout

The body is African mahogany, finished in Dark Tide Blue Flat. Ibanez lists the body shape as ST-style, while the RG model name places the guitar in the company's RG line. The flat blue finish and Cosmo Black hardware give the instrument a coordinated appearance, though finish preferences are subjective.

The left-handed designation is a key practical detail. This model is intended for a left-handed playing setup, rather than being a standard right-handed guitar with a different string arrangement. Buyers should confirm the control and bridge orientation suits their technique, particularly if they use a specific picking-hand approach or rely on familiar right-handed hardware layouts.

Neck and fingerboard dimensions

The bolt-on neck combines maple and wenge, with a rosewood fingerboard. Its Super Wizard HP profile is the named neck shape; the supplied data does not give a thickness measurement, so the profile name alone cannot establish whether it will suit a particular hand. Trying the neck, or checking its measured dimensions with a retailer, is the best way to judge that fit.

The scale length is 648 mm, also listed as 25.51 inches. That is a long-scale measurement, relevant to string selection and feel, though the exact tension depends on string gauge and tuning. The fingerboard radius is 430 mm, or 16.93 inches. That relatively broad radius measurement describes a flatter fingerboard curve than a smaller-radius design, but it does not by itself determine playing comfort or setup quality.

There are 24 jumbo stainless-steel frets and a 43 mm nut width. Stainless steel is the specified fret material, and jumbo describes the fret size. The combination gives players two concrete points to assess: whether the larger fret dimensions match their fretting technique, and whether the nut width feels suitable. The fingerboard uses offset mother-of-pearl inlays for position markers.

Pickups and controls

The guitar has a pair of Fishman Fluence Modern Ceramic humbuckers, one at the bridge and one at the neck. A three-way toggle selects pickup configurations, while the main controls comprise one volume knob and one tone knob. A separate Fishman Fluence voicing switch is also listed.

The specifications do not describe the available voicings or provide output, frequency-response, or wiring details. It would therefore be inaccurate to assign particular tones to the switch or predict how the pickups will behave with a specific amplifier. Buyers interested in the electronic options should consult Fishman's documentation for this exact pickup configuration and confirm the switching functions with Ibanez or the retailer.

Bridge, hardware, and included case

The Gibraltar Standard III is a fixed bridge, and the product has no tremolo. That makes the hardware layout simpler than a tremolo-equipped RG, but the specifications alone do not establish tuning stability, sustain, or ease of adjustment. The Cosmo Black hardware finish is a visual detail, not a performance claim.

A case is included, while no gig bag is listed. The distinction matters when comparing the package with other guitars in the same price range. Confirm with the seller which case is supplied and whether it is shaped for this left-handed model, especially if the instrument will be transported regularly.

Who should consider it?

The RG5121RL-DBF is a specification-rich option for left-handed players looking for a 24-fret guitar with two active Fishman Fluence Modern Ceramic humbuckers, a fixed bridge, and a maple and wenge bolt-on neck. Its 648 mm scale, 43 mm nut width, and 430 mm fingerboard radius give shoppers useful measurements to compare against instruments they already know.

At $1,999, the decision should rest on fit, sound, switching behavior, and setup after a hands-on check, not on assumptions drawn from the parts list. The published data establishes the materials and hardware, but cannot confirm how this individual guitar feels or performs. For buyers who need a left-handed instrument and want these specific components, it merits a closer inspection. Those who require a tremolo, a gig bag, or documented pickup-voicing details should verify those needs before ordering.
