Step back into the golden era of 1980s studio production with this legendary Yamaha SPX90 Digital Multi-Effect Processor. Released in 1985, the SPX90 revolutionized recording studios and live rigs by offering 30 high-quality digital effects in a single 1U rack space. It is globally revered for its signature crunchy 16-bit sound, defining the decade with its iconic Symphonic chorus and massive gated snare reverbs.

This specific unit is an absolute time capsule. It includes an incredible trove of original documentation, including the original warranty ID card and the physical sales receipt from September 26, 1986, matching the unit's serial number.

Condition:

Cosmetically, this unit is in Very Good condition. The faceplate is clean, the digital displays are bright and legible, and all buttons and knobs are present and intact. Functionally, the digital brain and screen work perfectly, but only the left output channel works. The right channel is dead, which is likely a hardware issue related to the physical output jack or the analog output stage. Because of this, it is being sold strictly as-is.
