A multi-level effects trs full effects, reverb, ...

UTILIZATION

This machine is really made for live, edit it all with ease.
This bug is almost in the racks of effects of all the providers!

SOUND QUALITY

The effects sound good but not great either, if you get bent over to do things that sounds good anyway.
I use it as a sound engineer in trs I am satisfied we could even say I like it a lot.

OVERALL OPINION

The SPX-990 is just made for live! and does it well trs.
