eqing is one of the most important things in djing imo, you can really define and be so creative with them

you cold have a 2 tune playing together and take out most of the bass so it sounds like the tune is progressing inot a breakdown, then you can build a tune up really nicely with eqs and drop the bass of a different tune back in! stuff like that is just not possible without eqing

eqing is all about showing off the best bits of a tune to the crowd too imo :)
