I am trying to find a replacement bridge with narrow string spacing (16.5 or 17mm) for a 4 string bass I just bought. However, this bass has a bridge with the 3 hole screw pattern and I can't seem to find any 4 string bridges that have my desired string spacing and the 3 hole screw pattern. I've looked into hipshot, babicz, schaller, etc. Anyone have any suggestions on where I can find what I'm looking for, or am I going to need to drill some new holes?
