The Yamaha SPX900 was the first SPX processor to feature full bandwidth, 20Hz to 20kHz. In doing so Yamaha put to rest the REV series of processors. As digital technology improved over time, Yamaha moved forward with just the one series of processors and given the success of the SPX series, the REV series was dropped and all efforts were put into SPX series.
