I was asked to make a 5 string bass for the bassist of a local band and we were thinking about getting this Hipshot bridge in gold: http://www.bestbassgear.com/hipshot-a-style-bass-bridges.htm but now he's thinking about graphite saddles on the bridge. Does anyone have any suggestions on either bridges that come with graphite saddles or maybe switching out the saddles on the Hipshot or another bridge? Do they even make graphite saddles for bass? Are Graph Tech products made of graphite? Any opinions on graphite vs. brass, aluminum, or steel? Thanks.
