Linda Manzer is a Canadian luthier known for her archtop and flat-top acoustic guitars. Manzer trained with Jean Larrivée between 1974 and 1978 and later with Jimmy D'Aquisto in New York. She has many well known clients including Pat Metheny and Carlos Santana. In 1984 Manzer pioneered use of the Wedge (on her famous Pikasso Guitar made for Pat Metheny) - a feature which she now uses on all her steel string guitars. The Wedge is an original Manzer idea which uses a tapering of the guitar's upper body making the strings easier for a player to see, and the guitar more comfortable to play.
