DeltaLab began in 1977 in Salt Lake City, originally building audio test equipment before moving into digital effects. Its breakthrough came with the DL 1 Time Machine in 1978, one of the first affordable digital delays to offer genuinely high quality sound and strong creative flexibility. DeltaLab went on to develop reverbs, multi effects units and guitar amps that became popular for their balance of performance and price. The brand remains known for producing reliable and great sounding digital processors that continue to find use with musicians and engineers worldwide.
