I have one of the old Soundgear 1000E basses with the Gotoh 3D bridge. I really like the bridge, the bass is just so-so I use it as a tenor bass now. This is a fiver bridge, but the four looks the same http://www.warmoth.com/thrift/misc/gotoh5Thrift.htm
I put a Gotoh 201 on my Jazz Bass, and I think it's a great bridge. They use the same one for some Modulus basses as well.
