Hand Size Comfortability
After taking into account the neck profile, scale size, fretboard radius, and nut width, we can conclude that the Ibanez RG421AHM's construction favors people with relatively small hands.
Nevertheless, this comes down in the end to personal preference. Make sure you test this guitar—or another one with similar characteristics—before buying.
Scale Length
Scale length is the distance the strings will span between the bridge and the nut. It can tell you a lot about the overall playability and tone of the instrument. A longer scale length means longer distance between frets, brighter tone and more string tension—which means lower action, but more difficult bending of the strings.
Here's the Ibanez RG421AHM's 25.5" scale length compared to other common sizes:
![Ibanez RG421AHM Scale Length Comparison](/images/comparisons/25.5-vs-24.75-vs-25.00-scale-length-comparison.jpg)
This is the same scale length used in Stratocaster guitars, and it's one of the main reasons they have such a bright sound. It's considered a long scale when compared to most non-baritone guitars.
Since the distance between bridge and nut is relatively long, you'll need to give the strings more tension to get them in tune. This higher tension will allow for a couple of things. First, you can get a lower action (get the strings closer to the fretboard) because the strings won't 'wiggle' too much when pluck and won't cause fret buzz. This can allow you to use lower tunings without increasing your string gauge, and it will make it easier to press down the strings fast.
However, the frets will also have a wider separation between each other, which can make it harder to play, especially if you got small hands. The higher tension will also make the strings feel stiffer, so bending will require more strength.
Neck Profile
![Ibanez RG421AHM Neck Profile](/images/comparisons/ibanez-wizard-iii-neck-profile.jpg)
The neck profile tells you the thickness (neck depth) and shape in cross section. Every difference will completely change the feeling and comfortability of the neck. This is a highly subjective thing, but most players indeed prefer certain types of necks (like Cs and Ds) because they feel nice in most hands.
The Ibanez RG421AHM's neck thickness is approximately 0.75'' (19.1mm) at the first fret, and 0.83'' (21.1mm) at the twelfth.
These measurements were taken either from the official Ibanez website, or, in case this information wasn't provided, by researching multiple online marketplaces and forums where owners of this model have posted their measurements.
It has a Wizard type neck. This is a neck profile invented by Ibanez in the 90s and perfected throughout the years. It's thinner than the C profile that most people like. It's not as thin as their 'Super Wizard' version, so it's a good option if you like thin necks, but like to have a bit of thickness for resting your hand while playing.
Fretboard Radius
When it comes to fingerboard radius, personal preference will dictate which one is better for you. However, most people seem to agree that a more curved (lower) radius will make it easier to play chords while a less curved (higher) radius is better for soloing and bending.
The Ibanez RG421AHM has a 16" fingerboard radius.
Here's an image comparing this fretboard radius to other popular choices:
![Ibanez RG421AHM Fretboard Radius Comparison with Fender Stratocaster and Gibson Les Paul](/images/comparisons/12-vs-16-vs-9.5-fretboard-radius-comparison.jpg)
This fretboard radius is really different than Stratocasters, but it's also a lot flatter than Les Paul fingerboards. It'll heavily favor soloing over playing chords. This doesn't mean you can't use it for chords, but it will be more comfortable to play chords without muting strings in a more curved fretboard. Bending and sliding without losing sustain will also be more likely in a flat fretboard like this one.
Compound radius fingerboards give the best of both worlds. Unfortunately, the Ibanez RG421AHM has the same radius across the board.

Nut Width
![Ibanez RG421AHM Nut Width](../images/comparisons/43-0-mm-nut-width.jpg)
The Ibanez RG421AHM has 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.
Frets
The Ibanez RG421AHM has 24 frets. A lot of people mistakenly believe that having more frets will always be better because it gives you a higher octave. This is certainly an advantage, but there's also a disadvantage to this.
Since the fretboard will be longer, the neck pickup will need to be placed closer to the bridge. And as you may know, the further away the neck pickup is from the bridge, the warmer it sounds. This means you'll have a brighter-sounding neck pickup when using a 24-fret guitar, even if you use the same pickup on a 22-fret guitar.
It comes with nickel silver frets, so they won't last as long as stainless steel frets. If you use your instrument a lot, you might need to replace the frets after a few years. But this is unlikely as most people change instruments before this happens.
Fret Size
![Ibanez RG421AHM Fret Size Comparison](/images/jumbo-fret-size.jpg)
Finally, let's talk about fret size. Some people prefer tall frets because it's easier to press the strings and perform bends since there's less friction against the fretboard. On the other hand, some people like shorter frets because they like to touch the fretboard when playing, or because they got heavy hands and tend to press too much on the string and alter the of the note pitch accidently.
The Ibanez RG421AHM's frets are Jumbo size. This is a tall fret size that is becoming increasingly popular because it makes it easier to press down the strings cleanly. With this fret size, you won't feel the fretboard when playing, so if you press down too hard, you will get the notes out of pitch. However, this is something you can overcome by getting used to the taller size.

Tone Analysis
Wood will have little influence in the final tone of an electric guitar or bass. Instead, the hardware, especially the pickups, will be the most important thing to look at. Bur first, let's see the quality of the wood.
Wood
![Ash wood pattern used for guitar building](/images/materials/ash.jpg)
![Maple wood pattern used for guitar building](/images/materials/maple.jpg)
Ash Body: The most popular Ash wood for guitars is swamp Ash. It has a really light color with beautiful patterns, which makes it perfect for a natural-looking finish. It's not as lightweight as Alder, but also not as heavy as Mahogany. It's known for producing a bright tone with solid mids and lows.
Maple Neck and Fretboard: This is one of the most popular types of wood used in all kinds of guitars. It's heavy, strong and compact, which makes it great for necks. However, it's also used for fretboards, bodies and tops due to its light color, resistance and beautiful patterns. When it comes to tone, it highlights the mid and high frequencies.
Pickups
Unfortunately, it doesn't come with pickups from one of the top brands. This doesn't mean you will get bad pickups, but you might want to consider a pickup upgrade after some time.
These are passive pickups, so you can expect a rounder sound and a moderade level of output.
The Ibanez RG421AHM's configuration is HH. With this pickup combination, you'll get warmer tones and more output than using single coils. Humbucker pickups cancel the noise that single-coil suffer from, which also results in a warmer tone. This pickup combination isn't only for high-gain music like Hard Rock or Heavy Metal. Their warmness is also popular for Jazz, Indie, R&B, Blues and more.

Versatility
It gives you a good amount of tone options with its 5-way switch. You can use it to choose at least 5 different pickup combinations.
Unfortunately, it doesn't come with more options for coil split or coil tapping. This makes it less versatile than some competitors.

What music genre is it good for?
As a 6 strings, Solid Body guitar with HH configuration and Passive pickups, we'd recommend it for genres like Hard Rock or similar. However, you can use almost any guitar for any genre. This is just the typical type of music for this particular one.

Build Quality Analysis
Country of Origin
Knowing where the instrument is produced is a good way to know how well it's built. Some manufacturing countries are known for having higher quality standards. For example, most expensive instruments are made in the US or Japan, but there are some exceptionally great countries—like South Korea—that are building a good reputation.
The Ibanez RG421AHM is made in Indonesia. Many people prefer the quality of an Indonesian guitar over a Chinese. Respectable brands like Epiphone, Ibanez and Schecter are building in this country because of the great quality and lower price. Some people like to compare them to the ones built in Japan during the 80s, when Japanese guitar makers made a name for themselves.
Still, remember that we're taking about Ibanez here, which is a brand with good renown. They know how to use cheap labor in this country without sacrificing too much quality. So you shouldn't end up receiving a useless or ugly instrument.
Bridge
F106: The advantage of fixed bridges is that they don't require any kind of set-up. This makes it extremely easy when changing strings because you don't need to adjust anything besides tuning the guitar. Also, the fact that the bridge is directly attached to the body will help to increase sustain. The disadvantage is the lack of versatility since you can't create the same vibrato effects as with tremolo bridges.
Nut Material
Another important thing to analyze is the nut material, as it's one of the most important aspects that can affect the sound and playability of your guitar. A well-cut nut will make sure it stays in tune and will make it more comfortable to play.
In this case, the Ibanez RG421AHM 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.
Neck Joint
The neck joint is the part where the neck of the guitar meets the body. There are three main techniques to attach both parts together: Set-In, Bolt-On and Neck-Through. The latter two provide different advantages, although neck-throughs are the most expensive.
This guitar has a Bolt-On neck joint. Even though this type of neck was looked down upon for a long time, nowadays bolt-on necks are well built and provide just as much sustain as any other join method. First of all, it's cheap to make because it consists of simply 4 bolts that attach the neck to the body. And you can travel with the guitar more easily, swap out the neck if you damage it, or upgrade to a more comfortable neck later on.
