I too have some "Only a Gibson is Good Enough" string protectors............I always chuckle when I read it............(notice they say "good enough" but NOT specifically for WHAT.

)
good enough to pass and get out the door
good enough to keep repair techs and luthiers busy for decades
good enough to teach you a lesson in value per dollar spent
good enough to need an immediate 300.00 worth of set up and fret work out of the box
good enough to tune but not intonate
good enough for 1/2 the pickups to work out of the box
good enough to............................................................to..........
Make ya wanna buy used........and let someone else work out the bugs and depreciation
so -- I am not just "hating" on the Gibbos ----because "only a Gibson is good enough"
