Gruvgear Fretwraps LG 3 Pack

i know it's an excessive simplification, but basically the "useful" part of the strings is everything between the nut and the bridge. the string segments between the tuners and the nut can be used for some 0/1 bending effect - but for the rest are basically a potential source of rattles and unwanted vibrations.
here come the string dampeners - of course they can be used in various positions, but the most common is behind the nut.
every absorbing material can be used as a dampener. hair bands, strips of tissue or soft paper... but they're all temporary, ugly, not really effective and quite graceless solutions.
the gruvgear string dampeners fit perfectly (they come in 3 sizes but can be easily adapted anyway), are absolutely effective and are easy and fast to adjust.
the only downside is the price - but they're worth it.

It's been a couple of weeks since I bought these string dampener (Gruvgear fretwraps) and I'm really happy with them. It's pretty easy to install one of them, takes no time , no harming no drilling to the guitar and you can adjust them easily.It really works and helps you to eliminate string noise especially for recording sessions, but some players like me would rather to use them all the time since they could help to have a enjoyable jam and practice. I use large size for seven and six strings.

Also, some say they are completely waste of money and pointless, but for some tapping technique and guitar licks especially in seven and eight string and they are really useful and work very well because it's very hard to dampen naturally at the same time when you're playing that particular licks and tapping technique so you have to use one these fretwraps if you want to play more clean.
