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

Nato wood pattern used for guitar building
Nato
Rosewood wood pattern used for guitar building
Rosewood
Spruce wood pattern used for guitar building
Spruce

Nato a hard and dense wood similar to Mahogany, but cheaper and not quite as hard. Tone-wise, it's also similar, but it doesn't have quite the same attack as 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.

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 FG840

Flame Maple wood pattern used for guitar building
Flame Maple

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

Winner: Yamaha FG840.

Electronics

Neither of them come with electronics that allow you to connect them to an amp. This makes them completely acoustic, so you'll need to use an external mic to record with them or play live.

Winner:Tie.

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 FG830 compares to the Yamaha FG840.

Country of Origin

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

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.

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 Plastic nuts. 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.

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. Both come with Die-Cast Chrome (TM29T).

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 FG830 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 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

Yamaha FG830 and Yamaha FG840'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 25.6".

It's very similar to a typical long 25.5" guitar scale, but with an extra inch probably to compensate the saddle position in acoustic guitars. It should be pretty much the same as a 25.5" scale guitar.

It will allow you to strum hard without hearing so much fret buzz, even with lower tunings.

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

Yamaha FG830 Neck Profile
Both guitars have the same 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 FG830 and the Yamaha FG840 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 FG830 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 Yamaha FG830 and the Yamaha FG840 have the same fretboard radius of 15.75". It's a radius that makes playing single notes (and bending, vibrato, sliding, etc) easier than on a classic Les Paul guitar. However, it's still more curved than some baritone and 7+ strings guitars.

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 .

Fret Size

Yamaha FG830 and Yamaha FG840 Frets Size
Both have a similar Medium fret size

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.
