The Ritter tremolo system for bass guitar operates with 4 high tech radial miniature-ballbearings.
The advantage of this construction is the 100% smooth action. It has no friction like a classical tremolo.

 

 

 

 

 

With a gear-driven spring tension adjuster you are able to regulate the spring tension without removing the instrument's rear cover plate.

 

The Ritter BB1 Tremolo System comes only with a RITTER bass. It's not sold seperately!
