a 100 Eur cheap Stagg Strat copy, made out of the cheapest wood possible, is it worth upgrading with parts worth 400 eur (good tremolo, pups, nut, etc.), or Would I be better off just buying a MIM Strat?
Buy a MIM strat, you'll have a better basis to upgrade upon later.
k thnx, just figuring out which of my guitars are worth upgrading which arent't
In most cases I'd say upgrading isn't worth it. However, if you want to do it to personalize your guitar and whatever, go for it.
