eigthies and early nineties where "technolgy" times, digital gear, luthier guitars , "modern" instruments, digital effects, etc...
but mid nineties were the back to old stuff and vintage gear.
mainly because of the grunge style, and people like Kravitz who used old gear again (old sounboards, old guiatrs, old amps...)
then for example, Gilmour started to use his old big muff again, while he used somme Boss gear (overdrive and delay) in the eighties
and Mark started to record in analog again, used old amps, and vintage guitares again : the 54 strat, later the 64 white strat, and the 61 again... and of course old Les Paul....
I tried to summ up this here :
