The Ibanez RG421EX in Black Flat is a streamlined hardtail RG designed around fast playability, powerful humbucker tones and straightforward reliability.

Its Wizard III maple neck, 25.5" scale, 24 jumbo frets and flat 400mm-radius fingerboard provide the quick, precise feel for which Ibanez RG guitars are known. A pair of Ibanez Quantum ceramic humbuckers combines with versatile five-way switching to cover tight rhythm sounds, high-gain leads and cleaner split-style textures.

The fixed bridge removes the setup considerations of a locking tremolo while providing a stable platform for alternate tunings and everyday use.

This example is presented in Very Good Condition, weighs just 6.46 lbs, and is sold without a case or gigbag.

What Makes The Ibanez RG421EX Special?

The RG421EX takes the familiar Ibanez RG formula and combines it with a fixed bridge, making it particularly attractive to players who want the speed and ergonomics of an RG without the additional setup involved with a floating locking tremolo.

Its Wizard III neck and 24-fret layout provide a modern playing platform, while the Quantum HH pickup system and five-way switching offer more tonal flexibility than a simple three-way dual-humbucker arrangement.

Wizard III Maple Neck

The Wizard III maple neck is built around the thin, flat feel closely associated with Ibanez performance guitars.

Factory dimensions are approximately:

• 43mm wide at the nut
• 58mm wide at the 24th fret
• 19mm thick at the 1st fret
• 21mm thick at the 12th fret

This makes it particularly well suited to:

• Fast alternate picking
• Legato
• Sweeping
• Wide stretches
• Technical chord work
• Lead guitar

400mm Fingerboard Radius

The fingerboard uses a very flat:

400mm / approximately 15.75" radius

This supports:

• Low action
• Wide string bends
• Fast lead playing
• Technical rhythm work
• Modern playing styles

24 Jumbo Frets

The RG421EX features:

24 jumbo frets

This provides two full octaves per string and gives plenty of room for:

• String bending
• Vibrato
• Legato
• Tapping
• Fast lead work

25.5" Scale Length

The guitar uses a:

25.5" / 648mm scale length

This provides:

• Firm string tension
• Clear attack
• Strong lower-string definition
• Familiar modern electric-guitar feel

It also works particularly well for lower tunings when paired with appropriate string gauges.

Dual Ibanez Quantum Humbuckers

The guitar uses two Ibanez Quantum passive ceramic humbuckers.

These pickups are designed for:

• Fast low-end response
• Defined rhythm tones
• Full midrange
• Clear high-gain articulation
• Strong lead sounds

Neck Pickup

The neck Quantum humbucker provides:

• Fuller lead tones
• Smooth sustain
• Warm cleans
• Fluid legato response

Bridge Pickup

The bridge Quantum humbucker offers:

• Tight attack
• Strong high-gain rhythm tones
• Clear palm-muted notes
• Focused lead sounds

Five-Way Pickup Switching

The RG421EX uses a five-way selector rather than a conventional three-way HH arrangement.

Depending on selector position, the switching provides combinations including:

1. Neck humbucker
2. Neck pickup in parallel
3. Neck and bridge humbuckers
4. Selected inner coils
5. Bridge humbucker

This provides considerably more tonal variety than a basic two-humbucker setup.

Fixed Bridge

The RG421EX uses a fixed hardtail bridge.

Benefits include:

• Stable tuning
• Straightforward string changes
• Easy alternate tuning
• Individual saddle adjustment
• No tremolo balancing
• Solid palm-muting platform

This makes it especially practical for players who frequently move between standard and dropped tunings.

Black Flat Finish

The Black Flat finish gives the guitar a stripped-back, modern appearance.

Combined with:

• Black hardware
• Black pickups
• Bound fingerboard
• Sharp RG body contours

it creates a particularly understated metal-oriented aesthetic.

Lightweight Feel

This individual guitar weighs:

6.46 lbs

That is notably light for a full-size solidbody electric guitar and should appeal to players who value comfort during long rehearsals or gigs.

Production Specification Note

The RG421EX has been produced for several years and some construction details have changed during that time.

Earlier examples can feature:

• Mahogany body
• Rosewood fingerboard

Later examples can feature:

• Meranti body
• Jatoba fingerboard

The shared RG421EX specification includes the Wizard III maple neck, 25.5" scale, 24 jumbo frets, Quantum HH electronics and fixed bridge.

Fixed Bridge & Alternate Tunings

The fixed bridge makes the RG421EX particularly convenient for players using alternative tunings.

Unlike a floating tremolo, changing tuning does not require the bridge spring tension to be rebalanced.

A significant change in tuning or string gauge may still require adjustments to:

• Intonation
• Neck relief
• Action

Case Note

No case or gigbag is included.

Suitable protection is recommended for regular transport.

Power Requirements

None.

The Quantum humbuckers and controls are completely passive.

No battery or external power supply is required.

Fair Deal Music Verdict

The Ibanez RG421EX in Black Flat is a straightforward, capable modern electric built around the essentials: a fast neck, powerful humbuckers and stable fixed bridge.

The Wizard III neck, 24 jumbo frets and flat 400mm radius provide the familiar fast-playing RG experience, while the Quantum pickups and five-way switching offer enough versatility for more than just high-gain metal tones.

The fixed bridge is particularly useful for players who use alternate tunings or simply prefer a lower-maintenance setup than a floating tremolo.

At only 6.46 lbs, this individual example is especially comfortable.

Presented in Very Good Condition and sold without a case or gigbag, it is a strong pre-owned choice for rock, metal and technical guitar players.
