I am looking for a relatively inexpensive (can be used, looking to spend under, say, $400) rack EQ unit that is good for mixdown/rough mastering (this is for a basement project studio, not a professional mastering facility). I always figured it would be best to get a 5 band parametric EQ, but i read somewhere on here that big 31-band graphic EQs are better for this kind of work. is there a serious difference or is it just a matter of personal interface preference? either way, can anyone recommend any specific models i should look for? thanks
