+1 to rharv's comment about bass. There are many sources online, even the little studio buddy app, that encourage bass guitar to get a little peak in the 1-4kHz region. Thumb-popped bass has lots of snap up in that region. If you roll it off, you'll take away all the bassist's hard work to get the pop.

Same goes for Kick drum as rharv stated to get the beater sound on the kick (almost all metal and hard rock released in the last 10-15 years has very prominent beater noise on the kick drum - to the point where I think some studios even add in that click using Drumagog or other such tools).

I mix live sound for our worship band (which is quite a rockin band - leader just got a gig as Big Kenny's touring guitarist), and the drummer is different every week. I'm almost always peaking 4 dB or so in that region on the rack toms and kick for 'presence' in the mix - one of the few times I boost anything too much live.
