I bought a fender strat from my friend and i wouldn't mind putting some money into upgrading it. I've heard changing the pick ups to better ones will help. If you have any other suggestions it would be much appreciated.

new tuners (Grover, Schaller, Gotoh) , bridge, and neck

Pickups are really the only tone difference you can make the rest is feel and staying in tune(so pickups should be first priority)

if i were you i would do lots of research before making any final decisions. Good Luck
