Their first digital reverberator, the REV1 (1984), was followed by the groundbreaking SPX90 in 1985, which made digital effects affordable and accessible. Known for its high-quality sound and ease of use, the SPX90 offered versatile effects like reverb, delay, and modulation. In the 1990s, Yamaha introduced the SPX900 and SPX1000, featuring advanced algorithms, high-quality pitch shifting, and stereo imaging.
