this may seem like a noobish question, if a guitar has trouble staying in tune, will switching out the hardware make a difference? if you put a higher quality bridge and tuners on a guitar, will it stay in tune better? or if a guitar is unstable for tunings, it's always unstable, no matter what.

Yes, but if your guitar is low end enough that you're having that much trouble, you'd probably be better off just replacing it.

A good set of tuners will do wonders for tuning stability. Dont need to be locking usually unless you use the wammy alot. But also could be how its strung, I can keep a knock off strat with cheap tuners in tune for long periods of time.

A Graph tech/ graphite nut should help to. You can either buy one of these off a guitarsite or use a pencil and draw/ put the lead/ graphite into the nut slots.
Good Luck anyway!
