How i would EQ a drum kit live/studio:
KICK -
Boost around 80Hz - 100Hz for "bass"
Cut around 300Hz to 500Hz for "posterity"
Cut around 200Hz - 600Hz to avoid conflict with other instruments
Boost around 2.5KHz for "attack"
*For "smack" sound = loosen head
SNARE -
Boost around 3KHz for "bang", 5KHz - 8KHz for "clarity/presence"
Boost around 100Hz to 250Hz for "bottom end"
Cut around 300Hz to 500Hz
*For "fat sound" = loosen head and snare a bit and cut low mids a bit and boost bass and highs a bit
*For "sharper sound" = tighten head & snare and boost highs & mids
TOMS -
Boost around 100Hz for "warmth"
Cut around the 300 to 500Hz
Boost around 5KHz to 8KHz for more "crispness"
Boost at 3KHz for "power" & sometimes 100Hz or 500Hz depending on song
*Cut area around 800Hz to eliminate "cardboard box" sound
*If you're losing toms in a mix with guitars boost around 3.5KHz
HIHATS/CYMBALS -
Cut around 200Hz
Boost 7KHz to 10KHz for "sizzle"
*If it's too bright cut 9KHz
all depends on your room too, sounds vary in different rooms, it could sound awesome in one room and completely shithouse in the next.
EQ certain frequencies you think need the most improving. It depends how you want it sounding.
Simple EQing
EDIT: Go onto a search engine there will be heaps of pages about EQing etc etc on google and stuff like that.
