All things being equal, yes.
Its a rough callibration and then a fine calibration. You tune the amps EQ (and in the case of the PB, 5150 and similar, the depth and presence) to that youre quite close to where you want to be, tonally, but on the slightly light and slightly dull side of it.
This is because the EQ pedal, despite it having very wide gain ranges for each band, is not a massive adjustment tool. They sound shitety and weird if you try and send any one band to an extreme. Youre looking to make 2-3db changes, optimally, but not more than 6 unless you really have to.
Then you bring the EQ in for some intelligent focus and reduction of certain parts of a guitars sound, as pertains to metal. As I said, palm mute emphasis in certain important frequencies, pick attack emphasis, fizz control is also an option, wooly mids control, if you experience any, grind-increase in the mids can give the illusion of additional tightness in the low end if not.
This may be more usefull than be saying what I do, as it may be that with your amp in your room/s you end up cutting low end to get it to not bloom so much, which will also increase tightness (this is what I meant before about tuning the 100-ish hz to the room; that frequency range is a really big deal to the low end of a metal guitar; in tunings like we use we really arent dealing with the fundamental of the lowest tone, its the first overtone, and this is doubly true in a mix)
You've got to know where the various 'parts' (if there really is such a thing, but its helpfull to think of it that way) of a metal guitar sound sit in the spectrum, then you can use an EQ all $%ing day long, no problem at all.

http://www.badmuckingfastard.com/sound/slipperman.htmlFirst: Lets look over some critical 'dirt guitar' EQ ranges and how they affect the myriad of choices/possibilities we might wish to examine in our undertaking. Bottom to top.
20-45Hz. Never say never. Just say rarely.
50-90hz Ahh the madness. Here's the 'swing' range in our 'chugging'.
100-150 Bottom of the meat.
180-240 Lo-Center of the meat.250-320 Hi-Center of the meat.
340-650 Danger Will Robinson. Top of meat/Bottom of mids. CRITICAL.
700-900 More danger. Hard to hear. Kills 'newbies' on contact. Will explain.
950-1.2k Pure Satan. Make or break ya. Easy to hear. Hard to control.
1.3k-1.6k Ditto the above.
1.7k-2.2k Top of the mids/Bottom of pick attack range. Oh, the fear.
2.3k-3.1k Middle of pick range. Picky de poison. Mucho Satania.
3.2k-4.2k Top of pick range. Pick out a nice coffin. Yer gonna need it.
4.3k-6.5k Bottom of fizz. Add Beefeaters for gin fizz. Guzzle many glasses.
6.6k-8k. Top of fizzy. Many will kill this range ruthlessly. Careful. Can O' wormies.
8k-10k Road to hell. Paved with good intentions. Enjoy. Not.
10-15k Less obvious road(s) to hell. Gravel. Lose a windshield up here.
15k-25k Same disclaimer as 25-40Hz. Can you say 'sometimes bandwidth matters'?
WhaddaWeGot? 17 ways(freq. ranges) to kill yourself?
OK. DISCLAIMER TIME FOR "OLD GUYS". I'm describing the Grand Canyon. We both know it. Can't REALLY be done.
Gimmie some rope and I'll hang myself impressively. Stop laughing, you pricks.

Bolded the bits that need to be really carefully ballanced for tight chugging, which are also the bits that are going to excite most room modes and make your chugging not tight.
