I have seen some interesting basses that use individual bridges for the strings. It's fairly obvious that this can be used for custom string spacing, there probably isn't a better way to do that! I was wondering, is there a sonic effect using individual bridges, and how are the bridges mounted on the bass? I've seen what appears to be a plate underneath, but I have also seen photos where screw inserts were put into the bass and the string bridged attached via screws to the inserts. Also, how would one ground the individual bridges easily? Thanks.
