As the title already says, are products like GHS Fast Fret (mods, not sure if mentioning actual products is allowed? ) actually useful?
Do they improve the sound/playability of your instrument? Or even just lengthen the lifespan of strings? Or are they more a gimmick?
Yeah, stupid of me, when I pressed “post” I was thinking “probably should’ve done a proper search first”.
I guess this thread can probably be closed.
