I was searching for something to dampen my guitars and bass strings, but for me, hairbands and similar stuff didn't quite cut it.

I've never played tennis nor do I know much about it, but I know that there are those dampeners. Would it be possible to install them on the strings to dampen them?

Thanks for your answer.

P.S.

I'm talking about this stuff :

I think they would vibrate against the fretboard tbh. I've tied scarves and even a football sock around the guitar neck on more that one occasion and it did the job decently.
