i found some real good pre wired pickguard assemblies for strats being sold on ebay
and those look like affordable ways to upgrade standard, stock strats

my question is, how hard is it to change the pickguard assembly as a whole?
i'd imagine that all i would have to do is unscrew the old one, disconnect it from the output jack and the spring claw (the ground wire),
and solder the new wires in the same places
however, i gotta ask cause i can never be sure

also, is wiring the assembly to the output jack any different among the types of pickups?
for ex, is wiring an assembly with single coils any different from wiring one with humbuckers??
