How to bring back that Sweet Music
Ouch. The Frustration that is Fret Buzz Reels in your Ears.

Bringing Back that Sweet, Sweet Music…

It’s been a long day, you’ve been up to your neck in alligators, your partner is working late, no dinner?

There’s literally nothing else for it. You’re picking up your guitar and chillin’ right out of space and time. It’s your escape.

You’ve worked hard to learn those chords, to buy your crafted acoustic peace of heaven – your one true love.
It’s getting cold and a chill is in the air as you lift it up and strike a chord.

Ouch. The frustration that is fret buzz reels in your ears. How did that happen – you think?

Humidity in your guitar body?
Believe it or not, your guitar has a built-in moisture content meter… you can feel it in your fingers!

As musicians, we’re often told that we need to maintain the humidity of our instruments. The nominally suggested value for this is between 45% and 55%, but in fact it’s not the humidity we should be concerned with, it’s actually the moisture content of the wood.

So, why does everyone specify humidity values if we are really interested in the moisture content in the tone wood?

Well, for two reasons: (1) Hygrometers are cheap whereas non-invasive moisture content meters are expensive; and (2) humidity and moisture content are loosely related.

You can get the wood of your guitar to have the ideal Moisture Content, without having to pick up a hygrometer, and we’re going to show you how to feel it in your fingers, hear it in the sound, and stop worrying about micro percentages of Relative Humidity.

How does Relative Humidity (RH) affect the Moisture Content (MC) of wood?
MC and RH are related. The relationship, however, is complicated, a little like you, your guitar and your significant other. It has to do with vapor pressures and equilibration. But in simple terms, it’s all about balance. This means that a change in RH will drive a change in the Moisture Content of the wood. That said, RH can change rapidly whereas wood is very slow. This is why we humidify, but also why measuring humidity can be a little misleading. If you’re feeling geeky you can read more here… Humidity

What does this mean for you and your guitar?
Changes in MC affect the shape of the sound board, which in turn affects the action. In severe cases you can see it just by looking at the top, but long before you see it, you will feel it when you play.

Adding moisture will cause the top to bow, raising the action – too much and you will find those barre chords harder to play. Whereas losing moisture will cause the top to sag, lowering the action – too much and you will start to get that dreaded fret buzz. The sound of the guitar is also another little tell-tale sign, albeit less obvious. A guitar with the right moisture content will have a fuller sound than one that is overly dry.

In the extreme, a lack of moisture can also result in the separation of the braces from the sound board, and separation of the saddle. Moreover, it can even result in cracks appearing in the sound board and/or the back of the guitar. As such, it is not something that should be overlooked.

So, what about the neck of the guitar?
Both the neck and the fret board have the same grain direction. They will not change length with changes in moisture but may change subtly in width. The good news is that intonation is not affected. However, as the neck dries out use of a fret board conditioner is recommended. And, if you’ve left it a little late you may begin to feel sharp fret ends. Fortunately, this can be simply fixed by filing them smooth. File them once in the dead of winter and chances are, you’ll never have to file them again!

So how do you know your moisture content is right?
Feel it in your fingers, hear it in the sound, and stop worrying about the perfect RH – You don’t actually need to know that, a hygrometer is just a guide, you’re feel is the truth – it’s that simple!

The answer is simple and the solution is finally fast and fuss free in 2020.
In the beginning humidifying your guitar body was an arduous task.

Unscrew a cap, fill with some weird gel, syringe in some “distilled water” and stick it between the strings or worse still wait hours for a sponge to absorb water and then stick it in a plastic box with holes in, like water isn’t going to drip inside your guitar if you accidentally knock it. And not only that you have to wait weeks before the humidity level returns in some cases. Or get a giant tube with another sponge in it, or a pack that goes in the bin when it’s used up – expensive stuff…

Not only that all of the OLD WAYS to humidify stop you playing, or force you to hide away your baby in a case. And we’re not saying that’s a bad thing, it’s more of a convenience thing. When the mood takes you to play – it needs to be fast – creativity dies in the flutter of a wing.

In 2020 all that changed.

A really clever product with twice the capacity of any other humidifier, that takes 25-40 minutes minutes to absorb a massive 75ml -90ml of clean tap water, that just slips inside your guitar or can be hung between the strings has finally arrived on the instrument humidifying scene.

Now you can’t get humidity supplementation like that anywhere else.
Science, Technology, Engineering & Math (STEM) have come together to create the ultimate humidity delivery system.

The technology employed is cutting edge – literally.

The Engineering comes from the heart of NASA engineers and the Math has calculated the exact time and absorption rate required for ideal humidity supplementation use, while making it fast to fill.

No lids, caps or sponges. All you have to do is add water. Easy, fast & efficient humidification. Leak Free. Lasts a whole lot longer than any other.

So remember, keep a Prolix Music Humidifier nearby, it only takes 25-40 minutes and all you do is add water – it doesn’t get easier than that, does it?

Slip it in the sound hole of your guitar and make sweet, sweet music.

Perfect to combine with the Diodarrio humidifier packs. Those packs maintain the right humidity and these will actually rehumidify those packets. I live in Denver which is a high desert, so it gets really dry here. Combining those two has allowed me to easily maintain my acoustic guitar.

Have a backup, all wood guitar. I had put in case, and had not touched in months. Pulled it out, and 1st and 2nd sting were fretting out at 11th fret on up. Filled up product, and put in guitar, and guitar back in case. After 4 days, no more fretting out. Plays like the when I bought it. 😁

Just refilled it after three weeks, and it appears to be exactly as claimed. Left in the soundhole of a guitar that stays out in the heated air, and the guitar seems happy with the process. I was concerned about the Fishman wiring and it sitting near the output jack but it looks like it coexists peacefully with the electronics. I would put this in the case vs soundhole for an enclosed instrument, but if it is a daily player drop it in and forget it for a couple weeks.

Only humidify when your guitar needs it. Not all the time. Too much moisture can be equally damaging.

Only humidify when you need to

Drop in the humidifier when the action gets too low, and remove it when that sweet action returns.

If you keep your guitar in a case, monitor the humidity inside the sound hole. When it drops below 45% RH you will know it is time to humidify, and when it exceeds 55% RH you will know it’s time to stop.

Finally, don’t be fooled by the outdoor humidity. Relative Humidity is temperature dependent. As such, heated indoor air is often much drier than the air outside.

Feel the Action

In severe cases you can see a dry or swollen guitar just by looking at the profile. But long before you see it, you will feel it when you play.

Too much Moisture Content will cause the bridge to lift, resulting in high action making it much harder to play, while too little, will cause the bridge to sink, lowering the action and causing fret buzz.

The sound of the guitar is also another little tell-tale sign, albeit less obvious. A guitar with the right moisture content will have a fuller sound than one that is overly dry.
