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 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.
Woods Used in the Jackson Pro Series Signature Jeff Loomis Soloist SL7
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.
Basswood is a lightweight type of wood that isn't as expensive as other popular choices for guitar building. It gives more power to the mid-range frequencies. Its color can vary from pale white to light brown. Find out more about Basswood.
Woods Used in the Ibanez GRGR221PA
Purpleheart (also known as Amaranth) is a hard, dense wood with a brilliant tone. As its name suggests, the purple color makes this wood look exotic.
Okoume is an affordable wood and one of the first to replace Mahogany when the prohibitions started. It's generally softer than Mahogany and the tone has warmer lows.
Winner: Jackson Pro Series Signature Jeff Loomis Soloist SL7.
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 Jackson Pro Series Signature Jeff Loomis Soloist SL7 has pickups from a more specialized brand than the Ibanez GRGR221PA. 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 Heavy Metal and similar genres.
You can purchase similar pickups to the Jackson Pro Series Signature Jeff Loomis Soloist SL7's and use them on any guitar:
The Jackson Pro Series Signature Jeff Loomis Soloist SL7's pickups are Active while the Ibanez GRGR221PA'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 Pro Series Signature Jeff Loomis Soloist SL7.
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 GRGR221PA gives you 5 switch options while the Jackson Pro Series Signature Jeff Loomis Soloist SL7 gives you 3. This means that the Ibanez GRGR221PA 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 GRGR221PA.
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 Jackson Pro Series Signature Jeff Loomis Soloist SL7 compares to the Ibanez GRGR221PA.
Country of Origin
The manufacturing country can tell a lot about the build quality of an instrument. The Jackson Pro Series Signature Jeff Loomis Soloist SL7 is built in South Korea while the Ibanez GRGR221PA is made in China.
South Korea was for many years the number one choice for mass-producing semi-premium guitars. They can build excellent guitars for a cheap price. Now, it's less common to find Korean guitars because Indonesia has proved capable of building guitars just as well, but likely for cheaper.
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: Jackson Pro Series Signature Jeff Loomis Soloist SL7
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 Jackson Pro Series Signature Jeff Loomis Soloist SL7 has a Locking nut. Instead of a regular nut, this guitar has a locking system that will lock down the strings at the nut, preventing it from getting out of tune. It removes one of the disadvantages of tremolo bridges, tune stability.
On the other hand, the Ibanez GRGR221PA 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: Jackson Pro Series Signature Jeff Loomis Soloist SL7.
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 Jackson Pro Series Signature Jeff Loomis Soloist SL7's brige is a Floyd Rose. This is a double-locking bridge system that allows you to perform techniques like dive bombs and pinch harmonics. The locking nut allows your guitar to stay in tune even after the most intense tremolo usage. The disadvantage is that it takes more work to change the strings and set up everything correctly.
On the other hand, the Ibanez GRGR221PA'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: Jackson Pro Series Signature Jeff Loomis Soloist SL7.
Tuners
Both come with regular tuners. The Jackson Pro Series Signature Jeff Loomis Soloist SL7's are Jackson Sealed Die-Cast while the Ibanez GRGR221PA'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 Jackson Pro Series Signature Jeff Loomis Soloist SL7 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 GRGR221PA 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.

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 Jackson Pro Series Signature Jeff Loomis Soloist SL7 has the wider nut with 47.6mm (1.875'') vs 43mm (1.693''). This is a 4.6mm (0.182'') difference
This means that it will be more difficult to do bar chords on the Jackson Pro Series Signature Jeff Loomis Soloist SL7, 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 Jackson Pro Series Signature Jeff Loomis Soloist SL7 has the longest scale: 26.5". The Ibanez GRGR221PA 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
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 Pro Series Signature Jeff Loomis Soloist SL7 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 GRGR221PA, on the other hand, has a GRGR neck. This neck is used in Ibanez's mass production guitars, and it's very similar to the Wizard profile in terms of shape and thickness.
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 Jackson Pro Series Signature Jeff Loomis Soloist SL7 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 .

Ibanez GRGR221PA:
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.
