I am trying to retrofit an old bass of mine with a bridge that can actually intonate the thing. I have a set of monorail bridges(individual string bridges) that match the other hardware I`m using. They also allow for the rather close string spacing. My problem is that they are too short height wise. I need about 3/16ths more out of each of them. The actual adjustment range up and down is pretty close to what the stock bridge is, so I am thinking of just making or having someone make me spacers to put under the bridge(s?). Any idea what material would be good? Wood is probably easiest for me to work. The bridge(s?) are made from aluminum, so maybe metal would be better? Any ideas? Thanks, Jake P.S. - Any idea if the individual pieces are considered one bridge when talking about the whole? Or does it make bridge plural?
