First do you really need a new bridge cuz it'll you about $60.00 for the bridge alone probably $30.00 for the tailpiece. So be sure you really need it or not.
Have the saddles on your bridge become so worn that you can't stay in tune?
if you want a black bridge and tailpiece make sure all of your hardware on your guitar is black
well actually i wanted to change the tailpiece and bridge for modifacation BTW my guitar is not black like on the link its trans. red and im finding for knobs too thanks
