What is a soundhole cover? A guide to how to use it for nighttime practice and preventing feedback.

"Can't play guitar as much as I want at night..." Are you struggling with this?

"I live in an apartment, so I worry about the volume and can't practice at night," or "My acoustic guitar is too loud when playing in a group"—if you play the acoustic guitar or ukulele, you've likely felt this frustration at least once.

That’s where a soundhole cover (mute/suppressor) comes in handy. It’s an item that lets you control volume with surprising ease just by covering the soundhole. In this article, I will share from a craftsman’s perspective the effects of soundhole covers, how to choose one, and even a "hidden benefit" that many people don't know about.

What is a soundhole cover? A quick review of its role

As the name suggests, a soundhole cover is a cover attached to the soundhole (the circular hole on the front) of an acoustic guitar or ukulele. It serves three main purposes.

1. Moderately reducing volume (muting)

The soundhole is the "exit for sound," where the vibrations of the strings resonate inside the body and are released outward. By covering it, you dampen the resonance and lower the volume. This allows you to play without worry during late-night practice or when your family is sleeping. The key is that it doesn't make the instrument "silent," but rather "moderately" quieter. Since there is enough volume left to check finger positioning and chord changes, you don't have to sacrifice the quality of your practice.

2. Suppressing howling (feedback)

When using an acoustic-electric guitar or nylon-string acoustic-electric at live shows or rehearsals, you may experience "howling"—a high-pitched feedback caused by the instrument picking up sound from the speakers. Covering the soundhole significantly suppresses this unpleasant feedback. For guitarists who use acoustic guitars on stage, it is truly a lifesaver.

3. Preventing dust entry

It’s often overlooked, but the soundhole is a large, open hole. By using a cover when the instrument is not in use, you can prevent dust from entering the body and keep your instrument clean.

The option of a genuine leather soundhole cover

While many commercially available soundhole covers are made of rubber or plastic, at 708works, we offer soundhole covers crafted from genuine (natural) leather.

The moderate softness and weight unique to leather provide both a muting effect and a secure fit. Unlike inorganic materials, it also has an elegant appearance when attached to your cherished instrument. For those who are particular about their gear and don't want to compromise on aesthetics just because it's a practice tool—this is an item we want you to experience.

For acoustic guitar players, we recommend the Soundhole Cover | For Acoustic Guitar [Genuine Leather]. It is excellent for reducing volume and also acts as a countermeasure against feedback during live performances with acoustic-electric guitars.

For ukulele players, please try the Soundhole Cover | For Ukulele [Genuine Leather]. Even with the small body of a ukulele, it allows you to adjust the volume perfectly for late-night practice or playing in large groups.

Installation is extremely simple

You might think installation sounds complicated, but rest assured. Simply lift the "tabs" on the back of the cover and hook them onto the edge of the soundhole. No tools are required, and you can set it up in seconds. It can be easily removed when not in use, allowing you to switch between "quiet practice" and "full-volume playing" depending on your mood.

Conclusion | A way to live with sound, without compromising

"Giving up on practice because of volume concerns" or "avoiding the stage with your acoustic guitar because of feedback fears"—such compromises might be resolved with just one small cover.
