Nevertheless, when it comes to choosing an instrument, you should pick the one more compatible with your personal style. Still, below we'll try you to give you our results as objectively as it's possible to help you decide.

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

Roasted Maple wood pattern used for guitar building
Roasted Maple

Roasted Maple is just maple without a finish. It's technically cheaper than regular maple, but it doesn't have any extra disadvantages because of this. The color is darker, and it's lighter weight and very stable even when there's a lot of humidity.

Woods Used in the Sterling Richardson7

Rosewood wood pattern used for guitar building
Rosewood
Alder wood pattern used for guitar building
Alder

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.

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 Ibanez RGD7521PB

Jatoba wood pattern used for guitar building
Jatoba
Nyatoh wood pattern used for guitar building
Nyatoh

Jatoba is a hard and dense wood that emphasizes the mid-lows, giving a fuller, more round sound than, for example, Mahogany. However, it also has a lot of clarity in the top end. Find out more about Jatoba.

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: Sterling Richardson7.

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 Ibanez RGD7521PB pickups from a more specialized brand than the Sterling Richardson7. Its pickups should give you a fuller, richer sound, although it all depends on what type of music you're going to play. We recommend these pickups for Heavy Metal 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: Ibanez RGD7521PB.

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 Sterling Richardson7 offers Coil Tap, Boost.

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.

A Boost will give your pickups more output, similar to an active pickup. It's great if you like to use a lot of output for heavy genres, but also like to use a cleaner tone often.

On the other hand, the Ibanez RGD7521PB 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.

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 Sterling Richardson7 compares to the Ibanez RGD7521PB.

Country of Origin

The manufacturing country can tell a lot about the build quality of an instrument. Both in this comparison where made in Indonesia.

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: Tie

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 Sterling Richardson7 has a Compensated nut. Each hole where the string sits at the nut is cut at a different distance from the bridge, which compensates for the different amount of tension that each string is subject to. This fixes most intonation issues across the fretboard, so it gives great tuning stability.

On the other hand, the Ibanez RGD7521PB 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: Sterling Richardson7.

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.

The Sterling Richardson7's brige is a Tremolo. Tremolo bridges give you more versatility than fixed bridges. They let you perform the intense vibrato effects that would be impossible with a fixed bridge. However, since the bridge floats and there's less contact with the body, the strings lose sustain slightly faster. They can also be a bit harder to restring and set up correctly than fixed bridges.

On the other hand, the Ibanez RGD7521PB's 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.

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 Sterling Richardson7 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: Sterling Richardson7.

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 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: 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

Sterling Richardson7 Nut Width
Sterling Richardson7 Nut Width
Ibanez RGD7521PB Nut Width
Ibanez RGD7521PB Nut Width

The nut width will affect the separation between strings at the nut. In this comparison, the Sterling Richardson7 has the wider nut with 49.5mm (1.95'') vs 48mm (1.89''). This is a 1.5mm (0.06'') difference

This means that it will be more difficult to do bar chords on the Sterling Richardson7, especially closer to the nut. However, it's also easier to play without muting strings accidently. This favors people with big hands.

Scale Length

Sterling Richardson7's Scale Length
Sterling Richardson7's Scale Length
Ibanez RGD7521PB's Scale Length
Ibanez RGD7521PB'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 RGD7521PB has the longest scale: 26.5". The Sterling Richardson7 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 RGD7521PB Neck Profile
Ibanez RGD7521PB'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 Sterling Richardson7 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 RGD7521PB, 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

Sterling Richardson7 Fingerboard Radius
Both Guitars Have The Same 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.

Both the Sterling Richardson7 and the Ibanez RGD7521PB have the same fretboard radius of 16". This fretboard radius is really different from Stratocasters, but it's also a lot flatter than Les Paul fingerboards. It'll favor plating single notes over playing chords. This doesn't mean you can't use it for rhythm, but a more curved fretboard offers better playability for chords. Bending and sliding without losing sustain will also be more likely in a flat fretboard like this one.

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 are balanced for most hand sizes.

Ibanez RGD7521PB's Frets Size

The Ibanez RGD7521PB has Jumbo frets, which should be taller than the Sterling Richardson7'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.
