The Engineering Edge
8-Cylinder Stability System
The #1 frustration for musicians is a shoulder rest that slips mid-performance. EFEL delivers 100% stability through our proprietary 8-Cylinder System.
These eight precision rubber cylinders utilize flexible wire mounting. As you play, the rollers slightly "flatten" against the instrument's surface, creating a secure, vacuum-like grip without ever risking the varnish. In 30 years, not a single musician has reported an EFEL falling off.
