Playability

The Ibanez JS140M meets 4 out of our 8 criteria items for beginner friendliness, which means that it's not bad for beginners, but it could be better. This takes into account the type of frets, scale length, nut width, bridge type, fretboard radius, and neck profile to determine the easiest combination for new players to get used to.

  • Easy-to-use bridge

Hand Size Comfortability

After taking into account the neck profile, scale size, fretboard radius, and nut width, we can conclude that the Ibanez JS140M'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.

Small Hands

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 JS140M's 25.5" scale length compared to other common sizes:

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 JS140M Neck Profile
Ibanez JS140M's neck profile

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 JS140M's neck thickness is approximately 0.79'' (20.1mm) at the first fret, and 0.88'' (22.4mm) 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 C type neck. C-shaped necks like this have been the most popular for the last years. The reason is that they feel good in most hands. It's generally a thin neck that doesn't get in your way when playing fast, but that also has enough mass to give your hands a comfortable grip for chords if they aren't too big.

Thin necks like this make it easier to move your hand across the neck and it helps when playing fast solos, especially if you like to leave your thumb free while playing high on the fretboard. However, thinner necks are also weaker and will need adjustment more often than a thicker neck.

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 JS140M has a 10" fingerboard radius.

Here's an image comparing this fretboard radius to other popular choices:

This is slightly flatter than the typical modern Stratocaster, but not by a lot. This radius will make it comfortable to play chords without muting strings accidentally. However, when compared to Strats, the extra .5 inches radius will make it slightly more comfortable to play solos without sacrificing too much chord playability.

Compound radius fingerboards give the best of both worlds. Unfortunately, the Ibanez JS140M has the same radius across the board.

Nut Width

Ibanez JS140M Nut Width

The Ibanez JS140M has a nut width of 42mm (1.654''). This is considered a narrow width for a 6-string guitar. This means that this guitar will have a narrower string separation at the nut, which will affect your fretting hand.

If you are a player with big hands, you might find it difficult to play chords without muting strings. However, this is good for players who have smaller hands, as it will allow them to reach each string more easily at the nut.

Frets

The Ibanez JS140M 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

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 JS140M's frets are Medium size. With medium frets, you can feel the fretboard more than with jumbo frets, but it's still easier to press the strings cleanly than with small frets; notes might change their pitch just slightly if you press hard on the fret. Also, if you need to do some fret leveling after years of playing, you'll have some room to sand them down without having to replace them.

Tone

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

Maple Neck, Fretboard

Basswood Body: This is a soft type of wood that is very light and easy to work with. It's cheaper than many other kinds of wood used for guitar building, but it doesn't mean it's low quality. In terms of sound, it accentuates the mid-range, which matches the frequencies that a Humbucker produces.

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 JS140M'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 comes with the popular 3-way switch that is present in most guitars. For more versatility, players tend to prefer a 5-way switch, although it all depends on what you want to use your guitar for.

It has a Coil Split option. It allows you to 'split' or turn off pickup coils to get even more tones in combination with the pickup selector. When used with humbucker pickups, it'll reduce the output and increase their clarity, turning them essentially into single-coil pickups.

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

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 JS140M 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

Edge-Zero II tremolo: It's a cheaper version of the Edge Zero bridge, which is a double-locking tremolo with some unique features. For example, a push-in arm, locking stud bolds that lock the bridge to the body to give better stabilization, and a thumb-screw that allows you to make adjustments without removing the backplate. When compared to the Edge Zero, this one makes changing the intonation a bit more difficult.

Some of them have an additional ZPS3 Zero Point system, which consists of two extra springs that will make the tremolo return back faster to the neutral position—also known as zero position. Like Floyd Roses, these tremolos can be a pain to set up if you're a newbie.

More with the same type of bridge:

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 JS140M has a Locking nut. Instead of the typical nut, this nut locks the strings in place and will make them stay in tune even after heavy tremolo use. This type of nut provides the best tune stability, but they also make the guitar more expensive.

It also comes with a retainer bar for the locking nut, which is a helpful addition. Without it, the strings would change pitch once you lock down the nut, so you'd have to make more micro-adjustments at the bridge to tune it correctly.

More with the same nut material:

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.
