I've purchased this set for my ESP EX, to replace the standard GOTOH parts that were on it. The bushings of the GOTOH bridge are the same size, so it was not necessary to use the ones that came with this set, especially since my guitar is black anyway. The preslotted bridge is super easy to install and to set up, but you can slot it a bit deeper if you really want. Massive tonal upgrade over the worn out bridge that was on my ESP.
