i cant get the action of my guitar down without having extremely bad string rattle/buzz.
is there anythin i can do to get my action lower.
You'll need to do bridge adjustments and possibly check your truss rod.

What kind of guitar/bridge do you have?
Ibanez RGA121 | ESP LTD H-1000
Axe-FX Standard
i have a epiphone les paul standard.
so its a stop bar tailpiece if thats what u mean.
If you don't know take it to a tech and get it set up. Worth every penny.
Also consider that if it's been played a lot, or has been exposed to extreme temperatures, the frets may need to be worked with.
ESP LTD EC-256 and a Fender Deluxe VM
