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 the Gibson Custom 1957 Les Paul Goldtop Darkback Light Aged
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.
Rosewood is an almost purple-looking wood that is used mainly for fretboards since it's heavy, rare, and expensive. It's sometimes used on acoustic guitar bodies to create stronger warm tones. Find out more about Rosewood.
Woods Used in the Ibanez RGRTB621 Iron Label
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.
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.
Nyatoh has been replacing Mahogany for guitar building. It's fairly hard, durable, more sustentable and common than Mahogany. Find out more about Nyatoh.
Winner: Gibson Custom 1957 Les Paul Goldtop Darkback Light Aged.
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.
However, the Gibson Custom 1957 Les Paul Goldtop Darkback Light Aged has a slight sound quality advantage when taking into account other factors like the type of pickups, magnet, position, etc.
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: Gibson Custom 1957 Les Paul Goldtop Darkback Light Aged.
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 RGRTB621 Iron Label gives you 5 switch options while the Gibson Custom 1957 Les Paul Goldtop Darkback Light Aged gives you 3. This means that the Ibanez RGRTB621 Iron Label gives you more options to find the right pickup combination for the type of sound you want to achieve
Only the Ibanez RGRTB621 Iron Label comes with some kind of pickup modification: Coil Tap.
Coil Tap is similar to Coil Split but it works a bit differently. Instead of completely cancelling one of the coils of the humbucker, it only cuts part of the output once activated. Some people believe this gives the split pickups a more real single-coil sound.
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 RGRTB621 Iron Label.
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 Gibson Custom 1957 Les Paul Goldtop Darkback Light Aged compares to the Ibanez RGRTB621 Iron Label.
Country of Origin
The manufacturing country can tell a lot about the build quality of an instrument. The Gibson Custom 1957 Les Paul Goldtop Darkback Light Aged is built in United States while the Ibanez RGRTB621 Iron Label is made in Indonesia.
The United States is considered one of the best electric guitar manufacturers in the world. A guitar made in this country is supposed to have world-class quality control. Nowadays, guitars made in other countries can beat some of the ones made in the US, but most of the time, this country offers the best you can get. Of course, that comes at a price.
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: Gibson Custom 1957 Les Paul Goldtop Darkback Light Aged
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 Gibson Custom 1957 Les Paul Goldtop Darkback Light Aged has a Nylon nut. It used to be one of the highest quality materials for nuts (and still is), but it's rare to find nowadays because it's hard to work with. It's a very resistant material with very low friction, so it will keep the guitar in tune and will last for a long time
On the other hand, the Ibanez RGRTB621 Iron Label comes with 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.
Winner: Gibson Custom 1957 Les Paul Goldtop Darkback Light Aged.
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.
Both come with a similar bridge: 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.
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: Tie.
Tuners
The Ibanez RGRTB621 Iron Label 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.
Winner: Ibanez RGRTB621 Iron Label.
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 Gibson Custom 1957 Les Paul Goldtop Darkback Light Aged 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 RGRTB621 Iron Label comes with Neck-Through neck joint. This neck is a lot more resistant and lets builders give the neck joint a more comfortable shape for soloing at the upper frets. The disadvantage is that they're more expensive and that if you damage your neck, you can't simply replace it like with bolt-on necks.
Winner: Ibanez RGRTB621 Iron Label.

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, the Ibanez RGRTB621 Iron Label has the wider nut with 43mm (1.693'') vs 42.9mm (1.688''). This is a 0.1mm (0.0050000000000001'') difference
This means that it will be more difficult to do bar chords on the Ibanez RGRTB621 Iron Label, especially closer to the nut. However, it's also easier to play without muting strings accidently. This favors people with big hands.
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 RGRTB621 Iron Label has the longest scale: 25.5". The Gibson Custom 1957 Les Paul Goldtop Darkback Light Aged 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 Gibson Custom 1957 Les Paul Goldtop Darkback Light Aged has a C type of neck. This is what you'll find in most modern guitars. Most people feel like the thickness of a C neck is simply the less intrusive one for playing fast, while at the same time allowing you to grab the neck easily for resting if you want to.
The Ibanez RGRTB621 Iron Label, 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 Gibson Custom 1957 Les Paul Goldtop Darkback Light Aged's fingerboard radius is smaller, which means it's more curved than the Ibanez RGRTB621 Iron Label'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 RGRTB621 Iron Label.
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''.
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 .
Gibson Custom 1957 Les Paul Goldtop Darkback Light Aged:
Ibanez RGRTB621 Iron Label:
Fret Size
Both have a Narrow Tall fret size. Their height is very similar to Jumbo frets, but they have a narrower crown. They won't let you feel the fretboard when playing, which will make it easier to get clean notes. However, if you press down too hard you might get the notes out of pitch.
