I made the switch from plastic to all brass just recently, my first thoughts were it sounds strange but at the price it's definitely worth a try. If you like the sound of your guitar as it is stick with the original hardware but brass will absolutely work to enhance the wood sound. Now I'm used to it I personally think it sounds amazing. To get the most out of it though make the full switch, saddle nut and bridge pins. What you have to take into account is you either want metal on metal or you don't.
