After noticing how much single replacement tuners cost, I bought the whole set. (The machine heads of my secondhand Les Paul had been butchered - with extra screw holes drilled etc. -- so I really needed these!) And yes, these Gibson Deluxe machine heads are the real deal, they work beautifully! The guitar stays in tune, the tuning ratio is optimal, there is no slack in tuning. So I recommend these, the genuine Gibson Deluxe tuners.
