When set up and used correctly, the result is a continuous sustained note that can be used as is, or treated to create new sounds or emulate traditional instruments.
In addition to his own instrument, based on a Tokai Stratocaster copy, Brook produced two other Infinite Guitars.
Additionally, it has been suggested that Brook was inspired by the Holland Infinite Sustain Guitar introduced prior to his design.
In 1978, guitarist Randy Roos and Steve Holland modified an SG guitar with a stainless steel fingerboard and infinite sustain device.
The musician and producer Jim O'Rourke has suggested that the concept did not originate with Brook, who refined previous similar designs by others.
