Sound Quality Comparison

The wood used in an electric guitar or bass is not as important to determine the final tone. However, some people prefer specific wood types, so we'll take a look at those first. Then, we'll take a look at the electronics to determine the versatility and sound quality of each instrument.

Woods Used in Both

Maple
Meranti wood pattern used for guitar building
Meranti

Maple is one of the most popular necks for good reasons. It is a strong wood that is relatively cheap to make and looks beautiful. The highest quality maple is the hardest that comes from North America. Find out more about Maple.

Meranti is an affordable wood used mainly for affordable electric guitars. It's generally lighter and softer than Mahogany. Find out more about Meranti.

Woods Used in the Ibanez RG421EX

Jatoba wood pattern used for guitar building
Jatoba

Jatoba is a hard and dense wood that emphasizes the mid-lows, giving a fuller, more round sound than, for example, Mahogany. However, it also has a lot of clarity in the top end. Find out more about Jatoba.

Woods Used in the Ibanez JIVAJR

Ebony wood pattern used for guitar building
Ebony

Ebony is a high-end wood, so it is not cheap. It's only used for fretboards because it's also very heavy. It does an excellent job as a durable material while looking elegant. Find out more about Ebony.

Winner: Ibanez JIVAJR.

Pickup Configuration

The Ibanez RG421EX has an HH configuration while the Ibanez JIVAJR has HSH pickups.

Double Humbucker (HH) is the choice for people who want a fuller, more round sound with tons of mids and lows. Humbuckers also get rid of the hum noise that plague single-coil pickups. They can work out for almost any genre going from Djent to even Jazz.

On the other hand, HSH is a versatile pickup configuration that will give you the high output, full tone, and quiet sound of humbucker pickups, but with the possibility of using a single coil for cleaner tones. The disadvantage is that the middle single-coil pickup will have a noticeable lower volume, so you might want to adjust the height of the pickups. Another problem is that if you set the middle pickup too high, it might interfere with your picking hand.

Pickups Quality

None of these use a specialized pickup brand for their pickups. Some of the best guitars on the market come with pickups from brands like EMG, Seymour Duncan, DiMarzio, etc. You might want to replace your pickups eventually if you want to get the best sound out of any of these instruments.

Both use Passive pickups. This is what's used for most music genres. They have a regular output and will serve you for both high-gain and clean tones. The alternative (Active pickups) offer a higher output that is mostly used for heavy music.

Winner: Tie.

Versatility Comparison

Some instruments offer you more ways to explore your creativity than others. Below you'll find how both compare when it comes to versatility.

Switch Options

Both are equal when it comes to the pickup switching option.

Neither of them come with some kind of coil split or pickup mod option. This makes both lacking in terms of versatility.

Build Quality Comparison

When it comes to build quality, we like to take into account everything used to build the instrument. This includes materials, hardware and the quality control expected depending on the country where it was built. Let's see how the Ibanez RG421EX compares to the Ibanez JIVAJR.

Country of Origin

The manufacturing country can tell a lot about the build quality of an instrument. Both in this comparison where made in Indonesia.

Indonesia is becoming the most popular country for guitar building because they can make good instruments for a low price. Some people think that they're 'the new China' when it comes to build quality. But the truth is that Indonesian guitars are more consistent, although Chinese quality has improved a lot in the last few years.

Winner: Tie

Nut Material

If you want your guitar to stay in tune and sound good, you need a well cut nut. Nut quality can be inconsistent even when comparing two copies of the same model. The best way to make sure you're nut will be well done is by getting a nut made by an expert company like TUSQ or Micarta.

The Ibanez RG421EX has a Plastic nut. This is a low-quality nut that you might want to consider upgrading soon. Bone and TUSQ nuts are the best for guitars with a fixed or simple tremolo bridge.

On the other hand, the Ibanez JIVAJR comes with a Locking nut. Instead of a regular nut, this guitar has a locking system that will lock down the strings at the nut, preventing it from getting out of tune. It removes one of the disadvantages of tremolo bridges, tune stability.

Winner: Ibanez JIVAJR.

Fret Material

Most fret wire is made of nickel silver. This material eventually wears down after a lot of use and most instruments end up needing a complete fret replacement. However, some expensive models come with stainless steel frets. This is what you should aim for if you can afford it.

Unfortunately, none of them come with stainless steel frets.

Winner: Tie.

Bridge

The perfect bridge for you will depend on your playstyle because they all have advantages and disadvantages. However, some bridges are more expensive—like Floyd Roses and Evertunes—and thus add more value to a guitar.

The Ibanez RG421EX's brige is a Fixed. It's a simple bridge that is very beginner-friendly since it doesn't require any set-up. You can swap strings easily. It might also give more sustain since it doesn't have complex moving parts that make the strings lose vibration. However, it doesn't have the same versatility as a tremolo bridge.

On the other hand, the Ibanez JIVAJR's is a Edge Zero II. This is a cheaper version of Ibanez's Edge Zero bridges. It comes with the same locking stud bolts that lock down into the body and provide better stabilization, and with easier adjustment of the springs without having to remove the backplate thanks to a thumb-screw. However, the intonation in this cheaper version will require additional work.

Edge Zero IIs that come with the ZPS3 Zero Point system have two extra springs that help return the tremolo to the neutral position faster. These bridges offer tons of versatility, but they also require more work than simpler tremolos to set up.

Since we need to be objective, the most expensive type of bridge will be the winner of this section. In the end, this doesn't matter if you're not going to use the bridge for its original purpose, so choose the bridge that fits your playing style better.

Winner: Ibanez JIVAJR.

Tuners

Both come with regular tuners. Both come with Ibanez.

Winner: Tie.

Neck Joint

Contrary to popular belief, the difference in sustain and tone that some neck joints give to a guitar is simply unperceivable—if they're all well built. However, some of them do have advantages over the others.

Both have a Bolt-On neck joint. This neck is joined to the body by 4 bolts that you can simply unscrew. This allows you to replace the neck or take it off for travel. It's the most common and cheapest way to build a guitar.

Winner: Tie.

Playability Comparison

Let's now compare their playability. Bear in mind that the instrument will feel different depending on your hand size and play style. That's why you should always test before buying. But if you can't or want a second opinion on it, we can still take a look at each of the important measurements of the instrument for you. This way, we can predict how easy a guitar might be to play, or how different it will feel compared to the other.

Remember that, even though the difference might seem small, every inch counts when it comes to feeling of the instrument in your hands. Any variation can completely change how comfortable a guitar feels in your hands.

Nut Width

Ibanez RG421EX Nut Width
Both Guitars Have The Same Nut Width

The nut width will affect the separation between strings at the nut. In this comparison, both have a nut width of 43mm (1.693'').

This is within the most common range of nut widths for a 6-string guitar. It offers a good balance of string separation at the nut. It's the size that most guitarists prefer as it gives them just enough space to play open chords without muting the strings, but without spreading the strings too wide and making bar chords difficult to perform.

Scale Length

Ibanez RG421EX and Ibanez JIVAJR's Scale Length
Both have the same scale length

The scale length is one of the things that influences playability the most. This is the distance between the nut and the bridge and will affect everything from low action allowance, difficulty to perform bends, fret separation, and even tone.

In this case, both have a scale length of 25.5".

This is the scale used in most Stratocasters. It's slightly longer than the typical 24.75'' size found in Les Pauls, and it's one of the main reasons why Stratocasters have such a bright sound in general. A longer scale also means that the strings will have higher tension. This will help you get lower action without suffering fret buzz, which will also be helpful when playing in lower tunings without having to increase your string gauge.

However, this also means that there will be more separation between frets, which can make it more difficult to play. Also, bending the strings will require more strengths due to the increased tension, but remember that a tremolo guitar will offset this difficulty.

Lastly, remember that you can also affect the tension of the strings by changing your string gauge. You can use a thicker gauge for more tension and a lighter one for less tension.

Neck Profile

Ibanez RG421EX Neck Profile
Both guitars have the same neck profile

No single neck shape is better than others. However, most people tend to prefer a thinner necks because it doesn't get in their way when playing fast and most hand sizes can adapt to it pretty well. However, some people still prefer thicker necks for a better grip, especially if they have big hands.

Both the Ibanez RG421EX and the Ibanez JIVAJR have a Wizard-shaped neck. This is thinner than most C-type necks. It won't get in your way if you want to play fast solos. It's not as slim as 'Super Wizard' necks, so it might fit you better if you don't like ultra-thin necks.

Fretboard Radius

Ibanez RG421EX Fingerboard Radius
Both Guitars Have The Same Fretboard Radius

Most guitar fretboards are not flat; they usually have a curve or arc across their width. A curved fretboard will make it easier to perform chords without muting strings, while a flatter one will make it easier to play single notes, which is good for bending and soloing in general. The best fretboards have a compound radius that varies across the fingerboard, but they're not common since they take a lot more work to build.

Both the Ibanez RG421EX and the Ibanez JIVAJR have the same fretboard radius of 16". This fretboard radius is really different from Stratocasters, but it's also a lot flatter than Les Paul fingerboards. It'll favor plating single notes over playing chords. This doesn't mean you can't use it for rhythm, but a more curved fretboard offers better playability for chords. Bending and sliding without losing sustain will also be more likely in a flat fretboard like this one.

Hand Size Comfortability

Everyone has a different hand size, and that's why it's recommended to try a guitar before buying, even if others tell you that it's comfortable to play. However, we can know whether a guitar favors small or large hands just by knowing its exact measurements.

After taking into account the scale length, nut width, neck profile and fretboard radius, we can conclude that both in this comparison favor small hands .

Fret Size

Ibanez RG421EX and Ibanez JIVAJR Frets Size
Both have a similar Jumbo fret size

Both have a Jumbo fret size. This is one of the tallest frets you can get. You won't feel the fretboard when pressing down the strings. It will give you the best sustain and all types of chords will be easier to play. However, you can end up changing the pitch of your notes if you press too hard, which is something people used to feeling the fretboard do when trying Jumbo frets for the first time.
