How Lightweight is it?
We found that the Jackson Pro Series Signature Jeff Loomis Soloist SL7 HT weighs between 7.313lbs (3.3kgs) and 7.938lbs (3.6kgs). This was recorded from some online retailers that publish the weight of the instruments they sell.
Playability
Scale Length
Scale length is the distance the strings will span between the bridge and the nut. It can tell you a lot about the overall playability and tone of the instrument. A longer scale length means longer distance between frets, brighter tone and more string tension—which means lower action, but more difficult bending of the strings.
Here's the Jackson Pro Series Signature Jeff Loomis Soloist SL7 HT's 26.5" scale length compared to other common sizes:

This scale is close to the popular 25.50" length, but adding an additional inch allows you to tune your strings lower while keeping the action low without causing fret buzz. This is useful for lower tunings, 7-string, or even classical guitars.
You want to avoid such a long scale if you don't plan to play in low tunings since the longer scale also means the frets are more separated, making it harder to play fast, especially for small hands.
Neck Profile

The neck profile tells you the thickness (neck depth) and shape in cross section. Every difference will completely change the feeling and comfortability of the neck. This is a highly subjective thing, but most players indeed prefer certain types of necks (like Cs and Ds) because they feel nice in most hands.
The Jackson Pro Series Signature Jeff Loomis Soloist SL7 HT's neck thickness is approximately 0.79'' (20.1mm) at the first fret, and 0.85'' (21.6mm) at the twelfth.
These measurements were taken either from the official Jackson website, or, in case this information wasn't provided, by researching multiple online marketplaces and forums where owners of this model have posted their measurements.
It has a D type neck. It's similar to a C shape, and it's one of the most common shapes right now. It's a bit flatter and thinner, even though sometimes it has a bit more shoulders. It's a fast type of neck that is comfortable, and shredders love it.
Fretboard Radius
When it comes to fingerboard radius, personal preference will dictate which one is better for you. However, most people seem to agree that a more curved (lower) radius will make it easier to play chords while a less curved (higher) radius is better for soloing and bending.

The Jackson Pro Series Signature Jeff Loomis Soloist SL7 HT has a compound fingerboard radius of 12" to 16".
A compound radius is the best you can get because you'll get the best of both worlds. It starts curved at the nut, but it flattens as you get closer to the body. This means that you'll get great comfortability for chords on the first few frets, but also a flatter fretboard for playing solos without problems on the higher frets.
Playability compared to main competitors

Nut Width

The Jackson Pro Series Signature Jeff Loomis Soloist SL7 HT has a nut width of 44.5mm (1.75''). This is considered a narrow width for a 7-string guitar. This means that this guitar will have a narrower string separation at the nut, which will affect your fretting hand.
If you are a player with big hands, you might find it difficult to play chords without muting strings. However, this is good for players who have smaller hands, as it will allow them to reach each string more easily at the nut.
Frets
The Jackson Pro Series Signature Jeff Loomis Soloist SL7 HT has 24 frets. A lot of people mistakenly believe that having more frets will always be better because it gives you a higher octave. This is certainly an advantage, but there's also a disadvantage to this.
Since the fretboard will be longer, the neck pickup will need to be placed closer to the bridge. And as you may know, the further away the neck pickup is from the bridge, the warmer it sounds. This means you'll have a brighter-sounding neck pickup when using a 24-fret guitar, even if you use the same pickup on a 22-fret guitar.
It comes with nickel silver frets, so they won't last as long as stainless steel frets. If you use your instrument a lot, you might need to replace the frets after a few years. But this is unlikely as most people change instruments before this happens.
Fret Size

Finally, let's talk about fret size. Some people prefer tall frets because it's easier to press the strings and perform bends since there's less friction against the fretboard. On the other hand, some people like shorter frets because they like to touch the fretboard when playing, or because they got heavy hands and tend to press too much on the string and alter the of the note pitch accidently.
The Jackson Pro Series Signature Jeff Loomis Soloist SL7 HT's frets are Jumbo size. This is a tall fret size that is becoming increasingly popular because it makes it easier to press down the strings cleanly. With this fret size, you won't feel the fretboard when playing, so if you press down too hard, you will get the notes out of pitch. However, this is something you can overcome by getting used to the taller size.
Playability Score
Tone
Wood will have little influence in the final tone of an electric guitar or bass. Instead, the hardware, especially the pickups, will be the most important thing to look at. Bur first, let's see the quality of the wood.
Wood



Basswood Body: This is a soft type of wood that is very light and easy to work with. It's cheaper than many other kinds of wood used for guitar building, but it doesn't mean it's low quality. In terms of sound, it accentuates the mid-range, which matches the frequencies that a Humbucker produces.
Maple Neck: This is one of the most popular types of wood used in all kinds of guitars. It's heavy, strong and compact, which makes it great for necks. However, it's also used for fretboards, bodies and tops due to its light color, resistance and beautiful patterns. When it comes to tone, it highlights the mid and high frequencies.
Ebony Fretboard: This is one of the most expensive woods there is, which is why it's mostly used for fretboards. It is dense, heavy, highly resistant and comes in a really dark color that gives any guitar a classy touch. Tone wise, it helps the high side of the spectrum and provides good sustain.
Pickups
This guitar comes with pickups from one of the top brands: Seymour Duncan. So you can expect well built pickups with great sound that shouldn't need an upgrade anytime soon.
These are passive pickups, so you can expect a rounder sound and a moderade level of output.
The Jackson Pro Series Signature Jeff Loomis Soloist SL7 HT's configuration is HH. With this pickup combination, you'll get warmer tones and more output than using single coils. Humbucker pickups cancel the noise that single-coil suffer from, which also results in a warmer tone. This pickup combination isn't only for high-gain music like Hard Rock or Heavy Metal. Their warmness is also popular for Jazz, Indie, R&B, Blues and more.
Versatility
It comes with the popular 3-way switch that is present in most guitars. For more versatility, players tend to prefer a 5-way switch, although it all depends on what you want to use your guitar for.
Unfortunately, it doesn't come with more options for coil split or coil tapping. This makes it less versatile than some competitors.
What music genre is it good for?
As a 7 strings, Solid Body guitar with HH configuration and Passive pickups, we'd recommend it for genres like Heavy Metal or similar. However, you can use almost any guitar for any genre. This is just the typical type of music for this particular one.
Sound Score
Build Quality
Country of Origin
Knowing where the instrument is produced is a good way to know how well it's built. Some manufacturing countries are known for having higher quality standards. For example, most expensive instruments are made in the US or Japan, but there are some exceptionally great countries—like South Korea—that are building a good reputation.
The Jackson Pro Series Signature Jeff Loomis Soloist SL7 HT is made in South Korea. Guitars made here are well-built and tend to have good quality control, even though they focus on mass production. This used to be the most premium option just below Japan or the US, but other countries like Indonesia are becoming great competitors because of even cheaper labor without sacrificing quality.
Bridge
Hipshot 7 Fixed .175: The advantage of fixed bridges is that they don't require any kind of set-up. This makes it extremely easy when changing strings because you don't need to adjust anything besides tuning the guitar. Also, the fact that the bridge is directly attached to the body will help to increase sustain. The disadvantage is the lack of versatility since you can't create the same vibrato effects as with tremolo bridges.
Tuners
The Jackson Pro Series Signature Jeff Loomis Soloist SL7 HT comes with locking tuners, which helps with tuning stability and makes changing strings a lot faster and easier. As long as they're high quality, these are the best tuning machines you can have. The only disadvantage is that they are a bit heavier than normal tuners.
Nut Material
Another important thing to analyze is the nut material, as it's one of the most important aspects that can affect the sound and playability of your guitar. A well-cut nut will make sure it stays in tune and will make it more comfortable to play.
In this case, the Jackson Pro Series Signature Jeff Loomis Soloist SL7 HT has a Ivory Tusq nut. This material is made to look, feel and sound like Ivory. It's made of organic polymers and doesn't contain oil or animal products. This is probably the highest quality nut you can get, so you can expect good tune stability and more clear tones when playing open strings. Most people seem to agree that it looks nicer than any plastic and even some bone nuts.
Neck Joint
The neck joint is the part where the neck of the guitar meets the body. There are three main techniques to attach both parts together: Set-In, Bolt-On and Neck-Through. The latter two provide different advantages, although neck-throughs are the most expensive.
This guitar has a Neck-Through neck joint. Many people believe a neck-through build delivers the best sustain because some of the vibrations from the neck aren't lost like with other neck joints. However, no one has been able to prove this. What we know is that a neck-through build is usually the most comfortable when playing the upper frets because there's nothing on your way at the neck-body joint.
