While these are cool looking and functional units, they often suffer from cheap controls (same as Mackie boards actually) which become very intermittent or inaccurate at extreme settings. So if you need this for serious use, I would recommend something more reliably built. Try the Rane PE series, Tascam PE40, or Orban, which are all better. Modern EQs are done well by Behringer, ART, and dbx. They are all similar to the Symetrix but retail for less. | SOLD Similar Units Available |
