Beginner Friendliness

The Epiphone Rex Brown Thunderbird meets 4 out of our 6 criteria items for beginner friendliness, while the ESP LTD FL-4 meets only 2. 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.

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 ESP LTD FL-4

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.

Alder is the most popular wood that Fender uses in most of their guitars nowadays. Even though they say it's because of its balanced tone with an emphasis in the upper midrange, it probably is because it isn't too expensive, and it's also pretty lightweight—more than Mahogany. Find out more about Alder.

Woods Used in the Epiphone Rex Brown Thunderbird

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.

Winner: Tie.

Pickup Configuration

The ESP LTD FL-4 has an H configuration while the Epiphone Rex Brown Thunderbird has HH pickups.

A single H pickup gives you the advantage of having a little longer sustain (all other things being equal) because there will be less magnetic fields from other pickups affecting the strings' vibration. However, they also give you the least versatility because you won't have other pickups at different distances from the bridge to create different tones. A single humbucking pickup is used for noiseless high output, which is used mainly for Hard Rock genres.

On the other hand, 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 ESP LTD FL-4 has pickups from a more specialized brand than the Epiphone Rex Brown Thunderbird. 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.

The ESP LTD FL-4's pickups are Active while the Epiphone Rex Brown Thunderbird'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.

Preamp Circuit

A preamp in an electric bass functions as an electronic circuit that acts as an interface between the bass's pickups and the amplifier. Its main purpose is to amplify and customize the bass's initial signal before it reaches the amplifier, offering enhanced control over factors like tone, volume, and sound attributes. Preamps typically come equipped with tone adjustments, equalization options, and sometimes built-in effects, empowering bass players to fine-tune their sound to suit their personal preferences and the musical environment.

Both basses have a Passive preamp.

Passive: A bass with a passive preamp lacks an onboard electronic circuit for tone shaping and signal boosting. Instead, it relies solely on passive pickups and basic tone controls, typically consisting of volume and tone knobs. Passive preamps don't require an external power source like batteries, making them low-maintenance and dependable. While they offer a simpler and more straightforward tonal character, passive basses are appreciated for their warm and vintage sound, often favored in genres like classic rock, blues, and funk. They are an excellent choice for musicians who value the simplicity and timeless appeal of their instrument's tone without the need for active electronic components.

Winner: ESP LTD FL-4.

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.

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: Epiphone Rex Brown Thunderbird.

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 ESP LTD FL-4 compares to the Epiphone Rex Brown Thunderbird.

Country of Origin

The manufacturing country can tell a lot about the build quality of an instrument. The ESP LTD FL-4 is built in Indonesia while the Epiphone Rex Brown Thunderbird is made in China.

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.

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: ESP LTD FL-4

Nut Material

If you want your bass 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 ESP LTD FL-4 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 Epiphone Rex Brown Thunderbird comes with a Brass nut. Guitarists used to love brass nuts due to the bright tone and good sustain they help achieve. However, now they use Bone more often since it can also produce a bright tone and longer sustain, but it's also oily, which helps to keep the guitar in tune.

Winner: Epiphone Rex Brown Thunderbird.

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 ESP LTD FL-4 is the only one that has stainless steel frets. These frets will basically last for the entire life of the bass. 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: ESP LTD FL-4.

Tuners

Both come with regular tuners. The ESP LTD FL-4's are Grover Mini while the Epiphone Rex Brown Thunderbird's are Gold Die Cast with Mini Clover Buttons

Winner: Tie.

Neck Joint

Contrary to popular belief, the difference in sustain and tone that some neck joints give to a bass is simply unperceivable—if they're all well built. However, some of them do have advantages over the others.

Both have 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.

Winner: Tie.

Here is the list of features that were considered when choosing the winner in the Features subcategory:

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 bass 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 bass feels in your hands.

Nut Width

The nut width will affect the separation between strings at the nut. In this comparison, the Epiphone Rex Brown Thunderbird has the wider nut with 41mm (1.614'') vs 40mm (1.575''). This is a 1mm (0.039'') difference

This means that it will be more difficult to do bar chords on the Epiphone Rex Brown Thunderbird, 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.

In this case, both have a scale length of 34".

This is a scale used for baritones and guitars with more than 6 strings. Since the scale is so long, the tension of the strings will be higher. This means that bending will require a lot more strength than with a shorter scale. However, it also allows you to use really low tunings without causing fret buzz and without needing to increase your string gauge too much.

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 ESP LTD FL-4 has a U type of neck. This is also referred to as ''baseball neck'' because of its shape. It's usually thick, which is why some people with big hands like it. However, they can also be thin, similar to a C shape, but with more shoulders for a better grip.

The Epiphone Rex Brown Thunderbird, on the other hand, has a C 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.

Fretboard Radius

Most bass 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 Rex Brown Thunderbird's fingerboard radius is smaller, which means it's more curved than the ESP LTD FL-4'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 ESP LTD FL-4.

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

The ESP LTD FL-4 has XL Jumbo frets, which should be taller than the Epiphone Rex Brown Thunderbird'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.
