All you do is get a hair tie the round elastic type (I use a scrunchie becuse the shape allows me to mute some strings and leave some open) and put it over the headstock and down to the neck. When you dont need it you can leave it sit right above the knut. When you need it just slide it down to a fret where you won't need the frets behind the hair tie. So if you solo from the 9th fret and up you can put the hair tie at the 8th fret. It mutes the strings so you can do fast stuff like tapping and sweeps without having to concentrate so much on muting. It is best not to lean on it too much you wanna learn to play as clean as possible but it really does make a huge difference.
