Nevertheless, when it comes to choosing an instrument, you should pick the one more compatible with your personal style. Still, below we'll try you to give you our results as objectively as it's possible to help you decide.

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 wood pattern used for guitar building
Maple
Poplar wood pattern used for guitar building
Poplar

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.

Poplar is a cheaper and heavier alternative to Alder wood. It terms of tone, it emphasizes the low-end and has cutting mids. It's relatively soft compared to most body woods. Find out more about Poplar.

Woods Used in the Ibanez GRX120SP

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 Jackson JS Series Dinky Arch Top JS32 DKA

Purpleheart wood pattern used for guitar building
Purpleheart

Purpleheart (also known as Amaranth) is a hard, dense wood with a brilliant tone. As its name suggests, the purple color makes this wood look exotic.

Winner: Tie.

Pickup Configuration

Both pickup configurations are HH. 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.

Pickups Quality

The Ibanez GRX120SP has pickups from a more specialized brand than the Jackson JS Series Dinky Arch Top JS32 DKA. Its pickups should simply give you a better, fuller sound, although it all depends on what type of music you're going to play. We recommend these pickups for Hard Rock and similar genres.

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: Ibanez GRX120SP.

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

The Ibanez GRX120SP gives you 5 switch options while the Jackson JS Series Dinky Arch Top JS32 DKA gives you 3. This means that the Ibanez GRX120SP gives you more options to find the right pickup combination for the type of sound you want to achieve

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 GRX120SP compares to the Jackson JS Series Dinky Arch Top JS32 DKA.

Country of Origin

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

China has a bad reputation when it comes to building quality. However, times have changed and now respectable brands use China's cheap labor to build good instruments for a lower price. Don't discount a guitar only because it was built in China, but also expect more quality from countries like Korea.

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 GRX120SP 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 Jackson JS Series Dinky Arch Top JS32 DKA 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: Jackson JS Series Dinky Arch Top JS32 DKA.

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 GRX120SP's brige is a Tremolo. Tremolo bridges give you more versatility than fixed bridges. They let you perform the intense vibrato effects that would be impossible with a fixed bridge. However, since the bridge floats and there's less contact with the body, the strings lose sustain slightly faster. They can also be a bit harder to restring and set up correctly than fixed bridges.

On the other hand, the Jackson JS Series Dinky Arch Top JS32 DKA's is a Floyd Rose. This is a double-locking bridge system that allows you to perform techniques like dive bombs and pinch harmonics. The locking nut allows your guitar to stay in tune even after the most intense tremolo usage. The disadvantage is that it takes more work to change the strings and set up everything correctly.

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: Jackson JS Series Dinky Arch Top JS32 DKA.

Tuners

Both come with regular tuners. The Ibanez GRX120SP's are Ibanez while the Jackson JS Series Dinky Arch Top JS32 DKA's are Jackson Sealed Die-Cast

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 GRX120SP Nut Width
Ibanez GRX120SP Nut Width
Jackson JS Series Dinky Arch Top JS32 DKA Nut Width
Jackson JS Series Dinky Arch Top JS32 DKA Nut Width

The nut width will affect the separation between strings at the nut. In this comparison, the Jackson JS Series Dinky Arch Top JS32 DKA has the wider nut with 42.9mm (1.688'') vs 42mm (1.654''). This is a 0.9mm (0.034'') difference

This means that it will be more difficult to do bar chords on the Jackson JS Series Dinky Arch Top JS32 DKA, especially closer to the nut. However, it's also easier to play without muting strings accidently. This favors people with big hands.

Scale Length

Ibanez GRX120SP and Jackson JS Series Dinky Arch Top JS32 DKA'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

Jackson JS Series Dinky Arch Top JS32 DKA Neck Profile
Jackson JS Series Dinky Arch Top JS32 DKA's 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.

In this case, both have different neck shapes:

The Ibanez GRX120SP has a GRGR type of neck. This neck is used in Ibanez's mass production guitars, and it's very similar to the Wizard profile in terms of shape and thickness.

The Jackson JS Series Dinky Arch Top JS32 DKA, on the other hand, has a D neck. This is a thin and flat neck that is made for playing fast. If you prefer a neck that doesn't get in your way when soloing, this is the shape you should use. Guitarists that prefer to have a bit more grip won't like this type of neck.

Fretboard Radius

Jackson JS Series Dinky Arch Top JS32 DKA Fretboard Compound Radius
Jackson JS Series Dinky Arch Top JS32 DKA's Compound 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.

In this case, the Jackson JS Series Dinky Arch Top JS32 DKA is the only one with a compound radius. This is a huge win because it will give you the best of both worlds: a more curved radius in the first few frets for chords, and flatter as you come closer to the body for soloing.

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.

And after taking into account the scale length, nut width, neck profile and fretboard radius, we can conclude that the Jackson JS Series Dinky Arch Top JS32 DKA favors large hands more than the Ibanez GRX120SP. But it's still more comfortable for people with small hands, as you can see in the score meter below.

Jackson JS Series Dinky Arch Top JS32 DKA's Frets Size

The Jackson JS Series Dinky Arch Top JS32 DKA has Jumbo frets, which should be taller than the Ibanez GRX120SP's Medium frets.

Some people prefer taller frets because they result in more sustain since the strings get pressed cleanly without interference from the fretboard. However, if they're too tall—like Jumbo frets—, you might change the pitch of the strings accidentally if you press too hard because you won't be touching the fretboard with your fingers. This is also why some guitarists with a heavy grip prefer smaller frets. They like to feel the fingerboard to avoid pressing down too hard and getting out of pitch.
