Rear view of Leo's 1968 to 1969 Telecaster development concept

Rear view of Leo's 1968 to 1969 Telecaster development concept. Two main points here. First, the string pull makes the saddle act as a lever, forcing the bottom side of the saddle against the body end grain. About 10 years later he found a more efficient way to transfer more string energy with his Saddle Lock bridge introduced on his G&L brand. Second, Leo was developing on-board active circuits powered by 9 volts (6 AAA batteries).
