Have you heard of the fret wrap ?
The product, developed by a manufacturer called Gruv Gear, looks like a wristband. It allows you to mute strings by putting it near the neck of the guitar or bass, but what exactly is the effect of fret wrap? I looked into it a little.

[Suppresses noise due to resonance]
In situations where it is difficult to mute, such as tapping, or playing in a high position, other strings may resonate and create unwanted sounds that you do not want to emit. However, by installing fret wraps and muting unnecessary sounds, you can obtain a clearer sound.
[Adjusts the sound of open strings]
Guitarists and bassists may have felt this before, but the sound and texture of a fretted sound and the sound of the open string are different. That can be adjusted with the fret wrap. When the fret wrap is installed just slightly touching the strings, the difference between the sound of open string and the fretted note is reduced.
[Tightens the sound]
By adjusting the degree to which the fret wrap touches the strings, you can suppress unnecessary vibrations, reduce overtones, make the sound tighter and make the sound clearer. Multi-string bassists and guitarists who use down tuning often use fret wraps to achieve this effect.
How was it?
I very much recommend fret wraps for those who prefer a delicate performance. The color variations are abundant and can give a greater impact to the overall sound! The prices are also reasonable. You will surely find a product that suits your tastes.
