I've got a 4 string Steinberger, and no string adaptor. Without this accessory, I can only string my bass with double-ball strings. Of course, 'Berger is only stocking the 5 string version... so I can't get a string adaptor. This leaves me with one option: double-ball strings. But the thing is, I haven't been impressed with steinberger's. Anyone know other brands that make them? What do you like? Thanks in advance.
