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 Epiphone Firebird

Mahogany wood pattern used for guitar building
Mahogany
Laurel wood pattern used for guitar building
Laurel

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.

There are many types of Laurel, but East Indian is the most common for guitar building. Its color can vary from dark to light brown with black lines. Many people find its tonality similar to Rosewood, which favors the warmer frequencies. Find out more about Laurel.

Woods Used in the Ibanez S521

Meranti wood pattern used for guitar building
Meranti

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.

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.

Meranti is an affordable wood used mainly for affordable electric guitars. It's generally lighter and softer than Mahogany. Find out more about Meranti.

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 Epiphone Firebird has pickups from a more specialized brand than the Ibanez S521. 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: Epiphone Firebird.

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 S521 gives you 5 switch options while the Epiphone Firebird gives you 3. This means that the Ibanez S521 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.

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 S521.

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 Firebird compares to the Ibanez S521.

Country of Origin

The manufacturing country can tell a lot about the build quality of an instrument. The Epiphone Firebird is built in China while the Ibanez S521 is made in Indonesia.

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.

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: Ibanez S521

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 Firebird 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 S521 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: Epiphone Firebird.

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

Both come with regular tuners. The Epiphone Firebird's are Grover Mini 18:1 ratio machine heads while the Ibanez S521's are Ibanez

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.

The Epiphone Firebird has a 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.

On the other hand, the Ibanez S521 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.

Winner: Epiphone Firebird.

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

Epiphone Firebird Nut Width
Both Guitars Have The Same 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

Epiphone Firebird's Scale Length
Epiphone Firebird's Scale Length
Ibanez S521's Scale Length
Ibanez S521's 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 S521 has the longest scale: 25.5". The Epiphone Firebird 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

Epiphone Firebird Neck Profile

Ibanez S521 Neck Profile
Ibanez S521'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 Epiphone Firebird 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 S521, 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

Epiphone Firebird Fingerboard Radius
Epiphone Firebird's Fingerboard radius
Ibanez S521 Fingerboard Radius
Ibanez S521's Fingerboard 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 Firebird's fingerboard radius is smaller, which means it's more curved than the Ibanez S521'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 S521.

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

Ibanez S521 Frets Size
Ibanez S521's Frets Size

The Ibanez S521 has Jumbo frets, which should be taller than the Epiphone Firebird's Medium Jumbo 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.
