The neck is slightly bowing outward, making it a bit difficult to play.
Although it’s a low-end model priced between 20,000 and 30,000 yen, it sounds fantastic—truly a testament to Yamaha’s quality.
I used to play a Yamaha acoustic guitar that I bought for around 30,000 yen that sounded amazing, and it seems the F600 is the model you can still get today.
After adjusting it, I found that the string action was on the low side for an acoustic guitar, making it very easy to play.
In the past, the nut height was high and the bridge string action was also high, so I used to have to adjust both of those points before playing. However, the current model is well-made in both respects and sounds great right out of the box, which is why it’s such a fantastic instrument.
I think this is more than enough for an acoustic guitar.
I understand you purchased this secondhand, but it’s in great condition.
When I tried it out, it felt almost exactly like a Sadowsky bass.
The parts seem to be the same as those on a Sadowsky, and I get the impression that both the playability and the sound are similar.
Price-wise, it seems to be in the same range, and since overseas brands tend to keep getting more expensive, I think this makes for a great option as an equivalent, compatible model that you can buy for less than a Sadowsky.
This is a guide to replacing the tension pins on the experimental Telecaster featured on YouTube.
The fact that “parallel-headstock guitars require a tension pin for the 3rd string” still hasn’t caught on at all among the general public.
As a result, there’s significant variation in tone, and chords sound bad.
Furthermore, the pressure on the 3rd string’s nut becomes extremely weak, so the open string doesn’t ring out fully—which only exacerbates the differences in tone between the strings.
To avoid this, a tension pin is needed for the 3rd string, but since most manufacturers lack technical expertise, very few have attempted to fix this issue.
Fender started installing tension pins on the 3rd and 4th strings in the 1980s, but it’s a mystery why they stopped doing so.
While a tension pin isn’t necessary for the 4th string, it is essential for the 3rd string.
In recent years, tension pins compatible with strings 1 through 3 have become available, and simply using these can significantly improve the sound.
The sound of the 3rd string becomes tighter and more resonant.
Simply put, the pressure on the nut—which the 3rd string previously lacked—increases, allowing the string to ring out fully and balance the tone with the other strings.
In particular, while the adjacent 1st and 2nd strings come with tension pins as standard and resonate fully, the 3rd string not only fails to resonate fully but also stands out negatively because it’s louder (due to improperly adjusted pole piece heights).
Since this issue with the 3rd string is completely eliminated, please replace your tension pins immediately with ones that work for the 3rd string as well.
They cost only about 1,200 yen, and this alone will improve the sound.
The tone will match that of the 1st and 2nd strings, and your chords will sound better.
You can see in the video how tension pins change the sound, but to be precise, what’s important is “applying the proper string tension to the nut.”
Please understand that this nut (contact pressure) is a major factor affecting the sound.
This also explains why the sound on Jaguar and Jazzmaster models can be poor; since the string tension on the bridge saddles is too weak, the strings don’t resonate fully, making a buzz-stop bar essential.
Remember that this contact pressure is essential for both the nut and the bridge; if it’s insufficient, the strings won’t resonate properly, leading to poor sound quality.
