Is it Easy to Play?

The Music Man JP15 6 meets 5 out of our 8 criteria items for beginner friendliness, which means that it's a good guitar to start with as a complete beginner. This takes into account the type of frets, scale length, nut width, bridge type, fretboard radius, and neck profile to determine the easiest combination for new players to get used to.

New Player Friendliness

  • Comfortable shape
  • Easy-to-use bridge
  • Locking tuners
  • Tall frets
  • Comfortable neck
  • Comfortable fretboard
  • Narrow nut
  • Short scale

Hand Size Comfortability

After taking into account the neck profile, scale size, fretboard radius, and nut width, we can conclude that the Music Man JP15 6's construction favors people with relatively small hands.

Nevertheless, this comes down in the end to personal preference. Make sure you test this guitar—or another one with similar characteristics—before buying.

Small Hands

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 Music Man JP15 6's 25.5" scale length compared to other common sizes:

This is the same scale length used in Stratocaster guitars, and it's one of the main reasons they have such a bright sound. It's considered a long scale when compared to most non-baritone guitars.

Since the distance between bridge and nut is relatively long, you'll need to give the strings more tension to get them in tune. This higher tension will allow for a couple of things. First, you can get a lower action (get the strings closer to the fretboard) because the strings won't 'wiggle' too much when pluck and won't cause fret buzz. This can allow you to use lower tunings without increasing your string gauge, and it will make it easier to press down the strings fast.

However, the frets will also have a wider separation between each other, which can make it harder to play, especially if you got small hands. The higher tension will also make the strings feel stiffer, so bending will require more strength.

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.

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 Music Man JP15 6 has a 17" fingerboard radius.

Here's an image comparing this fretboard radius to other popular choices:

Even compared to Les Paul guitars, this is a fretboard with a very flat curve. This means that this neck was made for playing single notes. This doesn't mean you can't use it for playing chords, but it will be more comfortable to play chords without muting strings in a more curved fretboard. Bending and sliding without losing sustain will also be more likely in a flat fretboard like this one.

Compound radius fingerboards give the best of both worlds. Unfortunately, the Music Man JP15 6 has the same radius across the board.

Nut Width

Music Man JP15 6 Nut Width

The Music Man JP15 6 has 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.

Frets

The Music Man JP15 6 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.

Finally, these are stainless steel frets. They're the best fretwire available. This means you won't need to change your frets since they should last as long as your guitar. Some people also feel easier bendings after swapping to stainless steel.

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 Music Man JP15 6's frets are Medium Jumbo size. These sit somewhere between a Jumbo and a Medium fret. They're not quite as tall as a full Jumbo, so you'll still feel the fretboard, but you won't feel it as much as with medium frets. This is a good size if you want to make it easy to press the strings but would also like a little bit of ''feedback'' to know when to stop pressing so the notes don't go out of pitch.

Tone Analysis

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

Figured Maple Neck, Fretboard

Okoume Body: It's an affordable wood and it was one of the first to replace Mahogany when prohibitions started. It's generally softer than Mahogany and the tone has warmer lows.

Figured Maple Neck and Fretboard: This wood has beautiful patterns only found in specific types of maple.

Pickups

This guitar comes with pickups from one of the top brands: DiMarzio. 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 Music Man JP15 6'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.

It has Multiple switch option. The first one is Coil Split. It allows you to 'split' or turn off pickup coils to get even more tones in combination with the pickup selector. When used with humbucker pickups, it'll reduce the output and increase their clarity, turning them essentially into single-coil pickups.

It also has a Multi-Voicing option. This means the pickups can change their output, tone, or sound. Piezo, Fishman and similar are considered multi-voicing pickups.

What music genre is it good for?

As a 6 strings, Solid Body guitar with HH configuration and Passive pickups, we'd recommend it for genres like Hard Rock or similar. However, you can use almost any guitar for any genre. This is just the typical type of music for this particular one.

Build Quality Analysis

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 Music Man JP15 6 is made in United States. Guitars made in the USA have the reputation of being the best instruments you can get. This statement isn't as accurate as a few years ago, but you should still expect top-quality from a guitar made in this country.

Bridge

Custom John Petrucci Music Man Piezo floating tremolo: This type of bridge allows you to change the pitch of the notes by pulling the bridge with the attached bar, which gives you better versatility. Also, since the bridge is not fixed to the guitar body, the bridge will move as you bend the strings. So you'll have to increase the distance of your bends to reach the same tension (note) compared to a fixed bridge. This allows you to perform smoother bends but will also make you slower. Finally, remember that this type of bridge requires a bit more maintenance than fixed ones, especially when changing strings.

Tuners

The Music Man JP15 6 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 Music Man JP15 6 has a Compensated nut. It's cut in a way that makes each string have the correct length for perfect intonation across the fretboard. It provides excellent tuning stability.

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 Bolt-On neck joint. Even though this type of neck was looked down upon for a long time, nowadays bolt-on necks are well built and provide just as much sustain as any other join method. First of all, it's cheap to make because it consists of simply 4 bolts that attach the neck to the body. And you can travel with the guitar more easily, swap out the neck if you damage it, or upgrade to a more comfortable neck later on.
