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


Mahogany is a fairly rare wood nowadays. It's used mostly for bodies due to its relatively lightweight. Gibson popularized it with their Les Paul guitars during their golden years, so this wood has a lot of good reputation behind it. The most expensive type comes from South America and it's still used by Gibson even today. Find out more about Mahogany.
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.
Woods Used in the Ibanez JCRG2103 j.custom

Wenge is a stiff wood that comes with straight and tight grains. Its color is dark brown and the tonality emphasizes the low and mid-ends (warm) frequencies, similar to Rosewood.
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
Both come with very good pickups from at least one of the specialized brands in the market. With pickups like these, you probably won't need an upgrade anytime soon.
We found the same or similar pickups to the Ibanez JCRG2103 j.custom's online:
The Epiphone Prophecy SG's pickups are Active while the Ibanez JCRG2103 j.custom's are Passive.
Passive pickups are what most guitars use. These have a normal output that works well for most genres. However, Active pickups are the preferred choice of heavy metal players because they offer extra output thanks to their 9v battery, which results in a heavier, more distorted sound. Bear in mind that achieving a completely clean tone with them won't be easy. So if you want to also use clean tones, you might want to avoid Active pickups.
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.
Both give you different pickup mod options.
The Epiphone Prophecy SG offers Coil Split, Multi-Voicing.
Coil Split lets you disconnect one of the pickup coils. When used with humbuckers, it turns them into single-coil with lower output and cleaner tone.
Multi-Voicing means the pickups come with multiple ''voices'', which means they can change the tone and gain by a simple switch or knob. Piezo, Fishman and similar are considered multi-voicing pickups.
On the other hand, the Ibanez JCRG2103 j.custom comes with the following: Coil Split.
Coil Split lets you disconnect one of the pickup coils. When used with humbuckers, it turns them into single-coil with lower output and cleaner tone.
When evaluating versatility, we also take into consideration bridge and neck joint type, number of frets, switch options, amount of pickups and more.
Winner: Ibanez JCRG2103 j.custom.
Final Sound Quality Scores
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 Epiphone Prophecy SG compares to the Ibanez JCRG2103 j.custom.
Country of Origin
The manufacturing country can tell a lot about the build quality of an instrument. The Epiphone Prophecy SG is built in China while the Ibanez JCRG2103 j.custom is made in Japan.
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.
Japan has a long history of high-quality guitar building. Little has changed in terms of their manufacturing and quality control over the years. Many guitars made in this country can be compared—and even beat—others made in the US.
Winner: Ibanez JCRG2103 j.custom
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 Epiphone Prophecy SG has a NuBone nut. It's made by the same company that makes TUSQ nuts. It's slightly softer but hard enough to give you a brighter sound when playing open strings. It's also self-lubricating, so it's good for tuning stability.
On the other hand, the Ibanez JCRG2103 j.custom 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: Tie.
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.
In this comparison, the Ibanez JCRG2103 j.custom is the only one that has stainless steel frets. These frets will basically last for the entire life of the guitar. They will never need polishing nor replacement. And not only that, but some people also notice that bending and vibratos are much easier to perform when they upgrade to stainless steel.
Winner: Ibanez JCRG2103 j.custom.
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 Epiphone Prophecy SG'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 JCRG2103 j.custom's is a Edge. This is a double-locking tremolo system designed by Ibanez. It's a tremolo inspired by Floyd Roses but with its own design improvements, like a push-in arm, better-positioned fine-tuners for more right-hand comfortability, replaceable knife edges, and more mass for more sustain. 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 JCRG2103 j.custom.
Tuners
The Epiphone Prophecy SG has the best tuners of the two because they are locking tuners. They'll help to keep your guitar in tune because they allow you to tune it without wrapping the strings around the posts. This avoids variations in the tuning due to the strings changing position at the post after a bend. They come at the disadvantage of being slightly heavier than regular tuners. Also, it makes it a lot easier to restring.
Nevertheless, the Ibanez JCRG2103 j.custom has a locking nut, so it should have even better tune stability and doesn't need locking tuners.
Winner: Epiphone Prophecy SG.
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.
The Epiphone Prophecy SG has a Set neck joint. This neck is tightly glued to the body. They give you the least versatility because you can't swap them for a neck that fits your hand better if you want to, unlike bolt-on necks. Some people think this gives more resonance and sustain, but there's no real difference if the bolt-on joint is well built.
On the other hand, the Ibanez JCRG2103 j.custom comes with 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.

Final Build Quality Scores
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

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


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.
The Ibanez JCRG2103 j.custom has the longest scale: 25.5". The Epiphone Prophecy SG is only 24.75" long. This is a 0.75'' (19.1mm) scale length difference.
This longer scale means that the strings need more tension to get in tune. This is good if you want to avoid fret buzz, which can happen when the strings are too loose and touch the frets while vibrating. This is especially important when playing in lower tunings. This will also let you reduce the gap between fretboard and strings (low action) to make them easier to press down. However, this higher tension will also make it harder to perform bends and vibratos as the strings will feel stiffer.
This also means that the frets have a longer separation between each other, so this will make it harder for people with smaller hands when playing some chord positions.
Another characteristic of a longer scale is that it makes the guitar sound 'snappier' or brighter. This is due to the extra separation between harmonics and overtones produced by the tension. This influences tone more than any other factor (except the pickups).
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


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 Epiphone Prophecy SG has a Asymmetrical type of neck. Even though this neck shape looks like a poorly-made job, it's, in fact, the neck that most naturally adapts to the arc of your hand when grabbing a guitar neck. You'll notice that the lower part of your palm makes a more pronounced, deeper curve while the upper part makes a more subtle arch. This is the shape that adapts the best to that natural arch your hand makes while playing.
The Ibanez JCRG2103 j.custom, on the other hand, has a Wizard 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


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 Epiphone Prophecy SG's fingerboard radius is smaller, which means it's more curved than the Ibanez JCRG2103 j.custom's. This extra arc will make playing chords easier in this model. You won't be as likely to mute the strings, especially if you have big hands. However, playing single notes and bending will be easier on the Ibanez JCRG2103 j.custom.
Still, both tend to favor soloing over chords, so if you're looking for a guitar for playing rhythm, you might want something else with a radius closer to a Stratocaster's 9.5''.
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.
