Edwardjeffrey and Dave,
I am new to forums and just noticed this post regarding narrow string spaced bridges.
I had a similar issue trying to find a bridge of these specs for an old Univox HiFlier bass I intend to refurbish. While i was not familiar with the Schaller 2000, it basically seems to be the same as their BB 3530 which i purchased from
http://www.dguitarparts.com/ .
I notice that Allparts sells this bridge for a whopping $150....not sure what they are smoking at allparts but i got the same bridge athttp://www.dguitarparts.com/ for about $75. They are a smaller store, have good prices and are nice folks to deal with. I had some credit card issues that required a few emails back and forth with a lady named Lynn to resolve, but she had patience and was a charm to deal with. Hope this helps
