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 the Schecter Keith Merrow KM-6 MK-III Pro

Maple wood pattern used for guitar building
Maple
Ebony wood pattern used for guitar building
Ebony
Ash wood pattern used for guitar building
Ash

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.

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.

Woods Used in the Music Man JP15 6

Figured Maple wood pattern used for guitar building
Figured Maple
Okoume wood pattern used for guitar building
Okoume

This wood has beautiful patterns only found in specific types of maple.

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: Schecter Keith Merrow KM-6 MK-III Pro.

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.

You can purchase similar pickups to the Schecter Keith Merrow KM-6 MK-III Pro's and use them on any guitar:

The Schecter Keith Merrow KM-6 MK-III Pro's pickups are Active while the Music Man JP15 6'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: Tie.

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 Schecter Keith Merrow KM-6 MK-III Pro offers 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.

On the other hand, the Music Man JP15 6 comes with the following: Coil Split, Multi-Voicing.

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.

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.

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 Schecter Keith Merrow KM-6 MK-III Pro compares to the Music Man JP15 6.

Country of Origin

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

The United States is considered one of the best electric guitar manufacturers in the world. A guitar made in this country is supposed to have world-class quality control. Nowadays, guitars made in other countries can beat some of the ones made in the US, but most of the time, this country offers the best you can get. Of course, that comes at a price.

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 Compensated nuts. 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.

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.

The Schecter Keith Merrow KM-6 MK-III Pro's brige 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.

On the other hand, the Music Man JP15 6's 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.

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.

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 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

Schecter Keith Merrow KM-6 MK-III Pro Nut Width
Schecter Keith Merrow KM-6 MK-III Pro Nut Width
Music Man JP15 6 Nut Width
Music Man JP15 6 Nut Width

The nut width will affect the separation between strings at the nut. In this comparison, the Music Man JP15 6 has the wider nut with 43mm (1.693'') vs 42mm (1.654''). This is a 1mm (0.039'') difference

This means that it will be more difficult to do bar chords on the Music Man JP15 6, especially closer to the nut. However, it's also easier to play without muting strings accidently. This favors people with big hands.

Scale Length

Schecter Keith Merrow KM-6 MK-III Pro and Music Man JP15 6's Scale Length
Both have the same 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.

In this case, both have a scale length of 25.5".

This is the scale used in most Stratocasters. It's slightly longer than the typical 24.75'' size found in Les Pauls, and it's one of the main reasons why Stratocasters have such a bright sound in general. A longer scale also means that the strings will have higher tension. This will help you get lower action without suffering fret buzz, which will also be helpful when playing in lower tunings without having to increase your string gauge.

However, this also means that there will be more separation between frets, which can make it more difficult to play. Also, bending the strings will require more strengths due to the increased tension, but remember that a tremolo guitar will offset this difficulty.

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

Music Man JP15 6 Neck Profile
Music Man JP15 6'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 Schecter Keith Merrow KM-6 MK-III Pro has a C type of 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.

The Music Man JP15 6, on the other hand, has a D 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.

Fretboard Radius

Music Man JP15 6 Fingerboard Radius
Music Man JP15 6'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 Schecter Keith Merrow KM-6 MK-III Pro 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.

And after taking into account the scale length, nut width, neck profile and fretboard radius, we can conclude that the Music Man JP15 6 favors large hands more than the Schecter Keith Merrow KM-6 MK-III Pro. But it's still more comfortable for people with small hands, as you can see in the score meter below.

Music Man JP15 6's Frets Size

The Schecter Keith Merrow KM-6 MK-III Pro has XL Jumbo frets, which should be taller than the Music Man JP15 6'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.
