I've owned and played on several models of Allen & Heath DJ mixers over the years, and they have a well deserved reputation for great build and sound quality. After picking up the Zed 12-FX, I can say the same is true for their studio mixers. If you're looking for a high quality studio mixer, with a small footprint and great price, look no further.
It is worth noting that the effects aren't great, which is why I give it 4 out of 5 stars. Had I not picked this up second hand for a great price, I likely would have opted for one the models without effects to save a little money.
