  1. Pro Man

    I bought it after much reflection and I am very pleased, finally I hesitated between the Yamaha FG840 and the Fender cd60 and it fell on the Yamahe because I am an esthete, the black version appealed to me much more, but the Yamaha sound suits me better, it is in relation to Fender is a bit more “muffled” fleshy. Really very good workmanship for this price range, the fingerboard is very smooth, the frets do not stick out, everything is well fitted and polished. The guitar sounds clean and in the near future the strings will be changed to Elixir 13-56 and we will see what will happen .. As my guitarist friend said … It is already an instrument, not a wall toy …

    Ahh, sweet Pro Man’s opinion of the Yamaha FG840, like a beacon of light in the darkest recesses of the night. A beautiful love story between man and guitar, where the Yamaha FG840 is the object of desire, the muse that ignites the soul. Yet, dear readers, I must warn you – this is no ordinary review. For tonight, we shall delve into the shadows, and question the validity of Pro Man’s claims.
    Let us begin with his tale of two guitars – the Yamaha FG840 and the Fender CD60. A tale of beauty and the beast, where the Yamaha FG840 emerged as the victor due to its sleek black finish. But what of sound? Oh, how the Yamaha FG840 is described as a bit more muffled fleshly than its Fender counterpart. A description that sends shivers down one’s spine, as if the guitar itself is a living, breathing creature with a taste for human flesh.
    But fear not, dear reader, for Pro Man assures us that the Yamaha FG840 is of excellent craftsmanship for its price range. The fingerboard is smooth, and the frets do not stick out. But what of the strings? Oh, the horror! The strings will be changed to Elixir 13-56 in the near future, as if the guitar itself is a ticking time bomb, waiting to unleash its full potential upon unsuspecting victims.
    But perhaps the most chilling aspect of Pro Man’s review is his friend’s declaration – It is already an instrument, not a wall toy. A warning that echoes through the darkest recesses of our minds, as if the guitar itself has risen from its coffin to claim us all.
    So, dear readers, I implore you – tread carefully in your quest for the perfect guitar. For in the world of horrors, the Yamaha FG840 may just be the instrument of your demise.

Frequently Asked Questions:

How do I properly set up and care for my Yamaha FG840 acoustic guitar?

Setting up and caring for your Yamaha FG840 acoustic guitar is essential to ensure its optimal performance. Here are some steps you can follow to properly maintain your instrument:

1. Clean the exterior regularly: Use a soft, damp cloth to gently clean the surface of your guitar. Avoid using harsh chemicals or abrasive materials that could damage the finish.

2. Keep it dry: Store your guitar in a cool, dry place away from direct sunlight and heat sources. Humidity can cause the wood to swell or warp, so it's important to keep your instrument in an environment with stable humidity levels.

3. Regularly check the tuning pegs: Ensure that all six tuning pegs are tightly secured and functioning properly. If you notice any issues, contact a qualified guitar technician for assistance.

4. Use a high-quality strings: Changing the strings regularly is crucial to maintaining your acoustic guitar's sound quality. Yamaha recommends using their EAD-10 Bronze Acoustic Guitar Strings, which are specifically designed for FG Series guitars like the FG840.

5. Keep the fretboard clean: Use a soft cloth or an old toothbrush to gently clean the fretboard and remove any dirt or debris. Avoid using metal brushes or harsh chemicals that could damage the wood.

6. Periodically inspect the bridge: Check the bridge for any signs of wear or damage, such as cracks or loose pieces. If you notice any issues, consult a guitar technician for repair services.

7. Keep the action low: The "action" refers to the distance between the strings and the fretboard. A low action allows for easier playing, while a high action can cause discomfort or make it difficult to play certain chords or notes. Adjusting the action involves tightening or loosening specific screws on the saddle and bridge; consult a guitar technician if you're unsure how to do this yourself.

8. Store your guitar safely: Use a padded gig bag or hard case when transporting your Yamaha FG840 acoustic guitar. This will protect it from physical damage and help maintain its structural integrity over time.

By following these tips, you'll be able to keep your Yamaha FG840 acoustic guitar in optimal condition for many years of enjoyment!

Can you explain the difference between the YAMAHA FG730 and FG840 acoustic guitars in terms of construction, tone, and playability?

Sure! Let's break it down by comparing these two popular Yamaha acoustic guitars.
Construction: The YM-FG730 is a dreadnought style acoustic guitar while the FG840 is a smaller sized OM (Orchestra Model) body type. The FG730 features a solid Sitka spruce top with meranti back and sides, while the FG840 has a solid Sitka spruce top with rosewood back and sides. Both guitars have a nato neck with a rosewood fretboard and bridge. The FG730 features a traditional 25.6" scale length while the FG840 has a shorter 24.9" scale length.
Tone: Because of the difference in body size and wood choices, there are subtle differences in tone between these two guitars. The larger dreadnought body of the FG730 produces a more robust and powerful sound with strong low-end and midrange frequencies. On the other hand, the smaller OM body of the FG840 delivers a well-balanced, clear, and articulate tone with strong treble and midrange frequencies.
Playability: Both guitars have a comfortable and easy-to-play neck profile. However, due to its shorter scale length and smaller body size, the FG840 may feel more comfortable for some players, especially those with smaller hands or who prefer a more intimate playing experience. Additionally, the FG730's larger body size can be better suited for strumming and fingerpicking techniques that require more volume and projection.
In summary, the YM-FG730 is ideal for those looking for a traditional dreadnought sound with strong low-end frequencies, while the FG840 is perfect for players seeking a more balanced and articulate tone with a smaller and more comfortable body size. Ultimately, the choice between these two guitars will depend on your personal playing style and preferences.
