Yamaha SPX90
Digital multi-effect processor


Yamaha SPX90

1986

A good reverb unit, with delay, chorus, flanging, short sampling and pitch changing. It was the second digital effect unit released by Yamaha after the D1500 digital delay, priced at around 600£.

It featured a MIDI interface for program changes so that effects could be swapped or controlled automatically. The onboard reverb and delays were praised for being good quality for the price, although the EQ wasn't very great. One effect at a time, with the ability to also sample a 500ms long audio ("freeze") to be edited and played back.

It quickly became a classic for small studio owners or home players and was still very well regarded in the early 1990s.

A revised SPX90 II was released a exactly a year later with few minor changes. Can be controlled with the RC7 remote unit.
