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

Spruce wood pattern used for guitar building
Spruce

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.

Woods Used in the Yamaha A1M

Mahogany wood pattern used for guitar building
Mahogany
Rosewood wood pattern used for guitar building
Rosewood

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.

Rosewood is an almost purple-looking wood that is used mainly for fretboards since it's heavy, rare, and expensive. It's sometimes used on acoustic guitar bodies to create stronger warm tones. Find out more about Rosewood.

Woods Used in the Martin 000Jr-10

Hardwood wood pattern used for guitar building
Hardwood
Richlite wood pattern used for guitar building
Richlite
Sapele wood pattern used for guitar building
Sapele

Hardwood is just a generic wood that can come from many species. This type of wood is used to build guitars because it provides a rich, warm sound. The wood also has good structural properties, making it durable and long-lasting.

It's very similar to Ebony, but it is much cheaper to make. The main reason is that it is made from resin-infused paper. It is very durable and soft, so it's often used for fretboards and tops.

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: Yamaha A1M.

Electronics

The Yamaha A1M 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 Yamaha A1M compares to the Martin 000Jr-10.

Country of Origin

The manufacturing country can tell a lot about the build quality of an instrument. The Yamaha A1M is built in China while the Martin 000Jr-10 is made in Mexico.

China has a bad reputation when it comes to building quality. However, times have changed and now respectable brands use China's cheap labor to build good instruments for a lower price. Don't discount a guitar only because it was built in China, but also expect more quality from countries like Korea.

Mexico has been for a long time where Fender has built their semi-premium series. If you don't want to overpay for a wellp-built instrument, a guitar built in this country by a good brand always offers good value for the money.

Winner: Martin 000Jr-10

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.

The Yamaha A1M has a Plastic nut. This is a low-quality nut that you might want to consider upgrading soon. Bone and TUSQ nuts are the best for guitars with a fixed or simple tremolo bridge.

On the other hand, the Martin 000Jr-10 comes with a Corian nut. It used to be the go-to nut for Gibson, but it's slowly being replaced by Graph Tech (Tusq). It's a synthetic material made to be similar to Bone, but it doesn't have the same self-lubricating properties, and it's less resistant.

Winner: Martin 000Jr-10.

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 Yamaha A1M's are Die-Cast Chrome (TM29T) while the Martin 000Jr-10's are Chrome Enclosed 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

Yamaha A1M Nut Width
Yamaha A1M Nut Width
Martin 000Jr-10 Nut Width
Martin 000Jr-10 Nut Width

The nut width will affect the separation between strings at the nut. In this comparison, the Martin 000Jr-10 has the wider nut with 44.5mm (1.75'') vs 43mm (1.693''). This is a 1.5mm (0.057'') difference

This means that it will be more difficult to do bar chords on the Martin 000Jr-10, especially closer to the nut. However, it's also easier to play without muting strings accidently. This favors people with big hands.

Scale Length

Yamaha A1M's Scale Length
Yamaha A1M's Scale Length
Martin 000Jr-10's Scale Length
Martin 000Jr-10's 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 Yamaha A1M has the longest scale: 25.6". The Martin 000Jr-10 is only 24" long. This is a 1.6'' (40.6mm) 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

Martin 000Jr-10 Neck Profile
Martin 000Jr-10'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.

Both the Yamaha A1M and the Martin 000Jr-10 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

Yamaha A1M Fingerboard Radius
Yamaha A1M's Fingerboard radius
Martin 000Jr-10 Fingerboard Radius
Martin 000Jr-10'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 Yamaha A1M's fingerboard radius is smaller, which means it's more curved than the Martin 000Jr-10's. This extra arc will make playing chords easier in this model. You won't be as likely to mute the strings, especially if you have big hands. However, playing single notes and bending will be easier on the Martin 000Jr-10.

Still, both tend to favor soloing over chords, so if you're looking for a guitar for playing rhythm, you might want something else with a radius closer to a Stratocaster's 9.5''.

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.

After taking into account the scale length, nut width, neck profile and fretboard radius, we can conclude that both in this comparison favor small hands .

Big Hands
Small Hands
Martin 000Jr-10:
