I searched for a thread on these, but couldn't find one. The new SoloRail is now available from Babicz/Full Contact Hardware. Its an individual saddle design. http://www.fullcontacthardware.com/fch-1-solorail-individual-bass-saddle I was super excited to see that these were available, because I don't like the wide string spacing of the regular 5 string Babicz bridges. Then I was quite disappointed to see that it would cost $230-$300 to buy 5 of them to put on a single bass.
