The Moog Guitar is an electric guitar developed in 2008 by Paul Vo that controls the level of energy within the strings of the guitar to modify the capabilities of the guitar. The guitar can send energy into strings to allow for infinite note sustain or the guitar can pull energy from the strings to create a short, staccato sound. The guitar also possesses harmonic blend control, allowing for new types of guitar harmonics to come out of the instrument. Unlike other technologies that help a guitar sustain notes, the Moog Guitar is unique as it is able to sustain notes on all six strings at once. All Moog Guitars except the custom shop ones built by Paul Vo, were Korean made guitars with Moog electronics.
