1 item left

The Yamaha SPX90 II is a legendary professional-grade 1U rack-mount digital multi-effects processor that helped define the sound of the 1980s. Building upon the massive success of the original SPX90, this "II" version expands the delay memory to a full 2,000 milliseconds, allowing for lush, expansive echoes alongside its world-famous symphonic, pitch-shifting, and gated reverb textures. Whether you are a studio engineer looking for authentic vintage outboard gear or a guitarist chasing classic rack tones, this unit delivers unmistakable character.

This specific unit is a fantastic collector's piece, originally purchased on March 9, 1988. It comes complete with a copy of the original receipt, the Operating Manual, and the Program Table.
