If you want an EQ with maximum power and versatility, get a Behringer DCX2496.
If you want a simple 10 band EQ for simple tonal adjustments, a superb model is the Pioneer GR-777 from the 90's. Low noise, super low distortion, superb build quality. It was sold as one of Pioneer's higher end products, and you will not be disappointed if you simply want a 10 band graphic EQ. They sold for about $400 in the early 90's, which would be about $700 by today's inflation level. But you can find them on eBay now for about $100-$150 in superb condition. Be sure the one you buy comes with the remote.
There were two versions of this unit. One with solid hardwood sides (for the Premiere line) and one with standard all black metal chassis. Other than this cosmetic part, the units were identical. Both are made in Japan, where Pioneer builds their highest end product lines. Lower lines are built in Malaysia/Asia.
