I don't play metal anymore, but when I did, my weapon of choice was an Ibanez SM-9 Super Metal.
These days, if I get nostalgic, I can relive the bad old days with a DigiTech Bad Monkey. Great range of very usable sounds, and enough adjustment that a separate EQ isn't really needed.
One problem though; the switching is not true bypass, so when it's turned 'off' it's a major treble-rolloff tone-suck. Use it as part of a switchable FX loop, and you'll love it. A lot of pedals are like this. You should definitely try before you buy.
