Schaller 3D-4 Bass Bridge CH

Used this one a custom fretless. The five screw attachment is solid, the intonation and height settings are fine, the curve is a bit extreme but not disturbing. Ended up not using the base plate - it's very useful to be able to set two different height profiles for the whole bridge with or without it. Holds tuning and sustains well.

My one gripe is the spacing adjustment - useful in theory, but in practice the little rollers move a bit too easily, and they are somewhat annoying, especially during restringing.

Super heavy, super quality. It's just right if your bass needs the extra weight at the bottom. Easy on the eye, easy to mount and adjust. This product is another good reason why I like Schaller. Why only 4 stars? Because you still need to fiddle strings through holes rather than to just hook them on the bridge. I'll keep it anyways.

Great bridge that is highly adjustable.
You still need to be aware that roller bridges have a limited width of string gauge allowed so go the schaller website to further info
