Bridge on the L-2000s

G&L saddlelock bridge (Leo's last bridge design)

 

There is a screw set into the side of the bridge that presses the saddles together.

 

Other bridges do the same thing (a Steinberger bridge does although the saddles are kind of "free floating" when not locked together). From what I can remember (the G&L site, G&L's site, probably has the whole story - or if not then The GLDP does) the bridge is massive and inset into a route in the body to make "fuller contact" with the body. Then the locking mechanism makes the entire assembly more rigid to fully transmit the string vibrations to the body & vice versa. This is designed to give the same type of performance as through-body stringing while allowing the strings to be terminated at the bridge.
