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
Nyatoh wood pattern used for guitar building
Nyatoh

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.

Nyatoh has been replacing Mahogany for guitar building. It's fairly hard, durable, more sustentable and common than Mahogany. Find out more about Nyatoh.

Woods Used in the Jackson X Series Soloist SLA6 DX Baritone

Laurel wood pattern used for guitar building
Laurel

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 RGRTB621 Iron Label

Ebony wood pattern used for guitar building
Ebony

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.

Winner: Ibanez RGRTB621 Iron Label.

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 Jackson X Series Soloist SLA6 DX Baritone has a slight sound quality advantage when taking into account other factors like the type of pickups, magnet, position, etc.

You can purchase similar pickups to the Jackson X Series Soloist SLA6 DX Baritone's and use them on any guitar:

The Jackson X Series Soloist SLA6 DX Baritone's pickups are Active while the Ibanez RGRTB621 Iron Label'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: Jackson X Series Soloist SLA6 DX Baritone.

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 Jackson X Series Soloist SLA6 DX Baritone 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.

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 Jackson X Series Soloist SLA6 DX Baritone 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 Jackson X Series Soloist SLA6 DX Baritone is built in China while the Ibanez RGRTB621 Iron Label 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 RGRTB621 Iron Label

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.

In this case, both have Plastic nuts. 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.

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.

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.

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

Jackson X Series Soloist SLA6 DX Baritone Nut Width
Jackson X Series Soloist SLA6 DX Baritone Nut Width
Ibanez RGRTB621 Iron Label Nut Width
Ibanez RGRTB621 Iron Label 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

Jackson X Series Soloist SLA6 DX Baritone's Scale Length
Jackson X Series Soloist SLA6 DX Baritone's Scale Length
Ibanez RGRTB621 Iron Label's Scale Length
Ibanez RGRTB621 Iron Label'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 Jackson X Series Soloist SLA6 DX Baritone has the longest scale: 26.5". The Ibanez RGRTB621 Iron Label is only 25.5" long. This is a 1'' (25.4mm) 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

Ibanez RGRTB621 Iron Label Neck Profile
Ibanez RGRTB621 Iron Label'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 Jackson X Series Soloist SLA6 DX Baritone has a D type of 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.

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

Jackson X Series Soloist SLA6 DX Baritone's Compound Fretboard Radius
Ibanez RGRTB621 Iron Label Fingerboard Radius
Ibanez RGRTB621 Iron Label'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 Jackson X Series Soloist SLA6 DX Baritone 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.

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 .

Fret Size

Jackson X Series Soloist SLA6 DX Baritone and Ibanez RGRTB621 Iron Label Frets Size
Both have a similar Jumbo 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.
