Sound Quality Comparison

The most important thing that will determine the tone of an acoustic guitar is the wood. Let's take a look at the differences between both .

Woods Used in Both

Ebony wood pattern used for guitar building
Ebony

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 Martin CEO-9

Mahogany wood pattern used for guitar building
Mahogany
Mango wood pattern used for guitar building
Mango

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.

Mango wood is a type of hardwood that comes from the mango tree. The tree is native to India, and the wood has a reddish-brown color with a grain that is similar to mahogany. Mango wood is often used in the construction of acoustic guitars because it produces a warm, full tone.

Woods Used in the Martin 00L Earth

Sipo wood pattern used for guitar building
Sipo
Spruce wood pattern used for guitar building
Spruce
Sapele wood pattern used for guitar building
Sapele

Sipo wood is a type of hardwood that is native to Africa. Regarding its tonal properties, the low end is full and rich, while the highs are clear and articulate. This makes for a very well-rounded sound that is perfect for any style of music.

Spruce has a light color with tight grain patterns. It's very stiff but relatively light. It's known for producing a well-rounded tone with a broad dynamic range. Find out more about Spruce.

It's similar to Mahogany in both color and tone. It can produce warm tones, and it's known for its beautiful figured grain patterns. Find out more about Sapele.

Winner: Martin CEO-9.

Electronics

The Martin CEO-9 comes with a preamp that allows you to connect it to an amp, unlike its competitor. This allows it to have more versatility and sound quality if you want to record with it or play live.

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 Martin CEO-9 compares to the Martin 00L Earth.

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 Bone nuts. It's a type of nut found in high-quality instruments. They sound similar to Ivory since they give a lot of sustain and a bright sound (at least when striking open strings). The only problem they can run into is that you may get a bone piece that simply doesn't sound as well as others because that's just how natural materials are.

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.

Tuners

Both come with regular tuners. The Martin CEO-9's are Vintage Copper Open Gear while the Martin 00L Earth's are Nickel Open Gear

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

Martin CEO-9 Nut Width
Both Guitars Have The Same Nut Width

The nut width will affect the separation between strings at the nut. In this comparison, both have a nut width of 44.5mm (1.75'').

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

Martin CEO-9 and Martin 00L Earth'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 24.9".

This is the scale found in most triple-O acoustic guitars. It's still considered a long scale, but shorter than the standard 25.5" scale.

A shorter scale length guitar has a few advantages. One is that it is easier to play because the strings are under less tension. This can be helpful for beginners, or those with smaller hands.

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

Martin 00L Earth Neck Profile
Martin 00L Earth'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 Martin CEO-9 has a V type of neck. This neck shape was more common during Fender's early years. Some people like it because they use their thumb over the edge of the fretboard to press the lower strings. It's rather thicker than most modern necks, so it's not usually used for playing fast solos.

The Martin 00L Earth, on the other hand, has a C 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

Martin CEO-9 Fingerboard Radius
Both Guitars Have The Same 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 Martin CEO-9 and the Martin 00L Earth have the same fretboard radius of 16". This fretboard radius is really different from Stratocasters, but it's also a lot flatter than Les Paul fingerboards. It'll favor plating single notes over playing chords. This doesn't mean you can't use it for rhythm, but a more curved fretboard offers better playability for chords. Bending and sliding without losing sustain will also be more likely in a flat fretboard like this one.

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 Martin CEO-9 favors large hands more than the Martin 00L Earth.

Both have a Medium fret size. If you like feeling the fretboard when you play, but also appreciate some easiness to press down the frets, this size offers a good balance for that.
