my strat's tremolo needs sorting out so i wondered whether anyone could help me. i have three springs in the back for the tremolo. whenever it use the arm, it doesn't return to the correct pitch, of course causing all kinds of trouble for me. i tried a fourth spring in the back but that made no difference (and i don't want all the tension of five springs).

feel free to ask any more questions about things that i haven't included.
What kind of tremolo is it? And what is your understanding of 'using the arm'?
just a normal strat tremolo with six screws and when i use the tremolo its nothing brutal at all.
are the springs warped? what kind of shape is the nut in?
