Great 80’s sound

When the SPX came out in 1985, I grabbed one straight away. It was roughly half the price of a Rev 7 and did a similar job, but with a few additions of pitch shifting and a crude short sampling mode that I can’t remember if the option to control by midi was available. The reverb and multi effects were the main attraction for me and it did those very well. Infact when put in comparison to the Rev 7’s reverb, it’s very close indeed. I still have two SPX’s in my studio today and occasionally they get used on percussion sounds, but are only relegated to secondary use because I have a lot of other reverbs to choose from. As a general summary, they are well worth the money they go for today.

My first piece of outboard gear was a Yamaha REV7, and the SPX90 was the second. The SPX I still have and use, and it has been at the heart of some of my best mixes. Sure some of the programs are “grainy” or “bright” but many of them sit perfectly and the Symphonic is worth the price of this unit alone. (The REV7 was traded to a friend for a 1968 sparkle-top Rhodes Suitcase, and while I miss the reverb, I was the winner in that trade, no question.

Lovely old-looking rack, it has a bunch of warm-sounding, old-school reverbs which, summed with its other delays and psychoacoustic effects make a good unit even nowadays, specially if you search those old ’80/’90 warm, soft sound. I recommend it for genres like Rock, Funk, Electronic and for some cool sounding Jazz; its too hot-sounding for stuff like metal. Overall a good fx (also cheap!) to have in your rack.
