This seems not to be the original bridge for the eb0 gibson. The original bridge is one standing on two posts, and no adjustable sadles, but a fixed bridge. Later (1965? and further) they used a three pole bridge.
I know so well, because I'm searching for this two pole bridge for my '62 eb0. I can't use the three pole one, because this bass has the additional muting device underneath the bridge. Anyone suggestions where to become one? These things are hard to find in the Netherlands......
thanks for reading,
