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.
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.
Woods Used in the Solar E1.6AC

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.
Woods Used in the Solar A1.6BOP

Ash is a type of wood that Fender used almost exclusively in the 50s, and it's still used by many brands. It's a dense wood with a light color that works well for a transparent, natural finish because of its beautiful patterns. In terms of sound, it's known for emphasizing the mid and high frequencies, but with strong low end. Find out more about Ash.
Winner: Tie.
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 Solar E1.6AC 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 Solar E1.6AC's and use them on any guitar:
The Solar E1.6AC's pickups are Active while the Solar A1.6BOP'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: Solar E1.6AC.
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 Solar A1.6BOP gives you 5 switch options while the Solar E1.6AC gives you 3. This means that the Solar A1.6BOP gives you more options to find the right pickup combination for the type of sound you want to achieve
Only the Solar E1.6AC comes with some kind of pickup modification: Multi-Voicing.
Multi-Voicing means the pickups come with multiple ''voices'', which means they can change the tone and gain by a simple switch or knob. Piezo, Fishman and similar are considered multi-voicing pickups.
When evaluating versatility, we also take into consideration bridge and neck joint type, number of frets, switch options, amount of pickups and more.
Winner: Solar A1.6BOP.
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 Solar E1.6AC compares to the Solar A1.6BOP.
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.
In this case, both have Graphite nuts. It's a self-lubricating material that will allow the strings to slide over the nut without a lot of friction. It's a good type of nut if you want to have better tuning stability than with plastic, although it's not as resistant as Bone or Tusq.
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.
Both in this comparison come with stainless steel frets. These frets will basically last for the entire life of the guitar. 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: 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: Evertune. It will keep your guitar in tune and intonated until the next string swap. If you really like extremely subtle vibratos, this might not be the bridge for you because you won't be able to perform them as well. However, the fact that you won't need to tune your guitar is a huge advantage that many people will gladly pay the extra price for.
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
They both have 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.
Both of them have a 18:1 tuner ratio. This means that it will take 18 turns of the keys to give the tuning posts an entire turn. Higher ratio means more precise tuning (and more time spent tuning your gutiar). Most guitars have a 18:1 ratio, while the most precise tuning can be achieved with a 21:1 ratio.
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.
Both have a Set neck joint. This neck is tightly glued to the body. They give you the least versatility because you can't swap them for a neck that fits your hand better if you want to, unlike bolt-on necks. Some people think this gives more resonance and sustain, but there's no real difference if the bolt-on joint is well built.
Winner: Tie.

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, both have a nut width of 43mm (1.693'').
This is within the most common range of nut widths for a 6-string guitar. It offers a good balance of string separation at the nut. It's the size that most guitarists prefer as it gives them just enough space to play open chords without muting the strings, but without spreading the strings too wide and making bar chords difficult to perform.
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 Solar A1.6BOP has the longest scale: 25.5". The Solar E1.6AC is only 24.75" long. This is a 0.75'' (19.1mm) 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.
Both the Solar E1.6AC and the Solar A1.6BOP have a C-shaped 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 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 Solar E1.6AC and the Solar A1.6BOP have the same fretboard radius of 13.78". It's closer to the 12'' that most Les Paul guitars have, but it's a bit flatter. It'll make it easier to play single notes than chords, but it's still relatively comfortable for chords.
Fret Size

Both have a XL Jumbo fret size. These are really tall frets made like this so you don't meet any resistance when playing techniques like vibrato, bending, tapping, etc. They should make the guitar easier to play, but you have to be careful not to get the notes out of pitch by pressing down too hard, which might happen since the fretboard will be too low to stop your hand.
