Ok...i have recorded a few punk bands, soft core and mid core, and a little hardcore (no, non like blink 182 and sum41). First of all, i dont see how you can say that the drums are easy because they are by far the hardest to get. This is true in a most cases of any type of music. Getting the drums to come through the loud bass, guitar, and vocals is extremely hard. Even though you are not asking for tips on this, im giving them to you
. First of all, the kick is probably one of the hardest to get to come through. Head off, extremely padded, quarter on beater, and mic right up to the head and maybe pointed up to the edge of the beater will help give you a dry snappy sound. I usually end up squashing the kick with compression, and even a sonic maximizer at times to bring this out. Usually i also need to EQ the kick like mad. Its important the highs are coming through for the click. I usually boost at 3-6k around 3-6DBs although i have gone as far 9-12DB (im going to try and avoid that with mic placement next time). The kick should be 3-12k dominant in sound, but with a bit of oomph still around the 90k.
The snare i find is usually not high frequency dominant, but usually mid dominant. I usually get this by dampanening the highs out a bit level a dry snap and punch in the mid. Dont dampen all the highs out, but i believe its definately 2-6 dominant like the kick.
Toms are usually not problem, but again are 2-6k dominant. I dampen the toms alot to give alot of click again. (BTW, i usually try and make the kick just sound like a punchy low tom, giving them the same kind of sound).
Overheads - i usually try to get mainly cymbals with overheads, although its nearly impossible. The overheads usually give too much roominess and doesnt let the drumset come out infront like it should in punk recordings so get them close to the cymbals and right above. Maybe low cut at 250 if you are getting too much drum presense. I really generally do not like the sound of the room in overhead punk drums. Keep them dry and punchy. Generally i will cut around 2k to take out the harsh cymbal sounds and make them a little more wet sounding, but this is personal preference.
Compress only if you have too, but i will bet you will have to compress the kick for it to come through the mix.
Bass i find is more bass and low mid dominant with a bit of peak around 4k if it needs more cut. Compress this though to take out those harsh snaps you usually get. I think there is generally more low mids than bass in the bass ounds for punk but make sure theres enough for the bass to be heard.
One note before i keep going, as you have noticed, the things i have mentioned have all been 4k area dominant, you will need to worry about masking with this. I would kind of alternate these peaks. Generally i will boost the kick in around 6-9k, toms 2k, and bass if needed in the 6k. Not alot of seperation there but it can help. Expirement, but i think the kick comes first in those frequencies. Also, try and get this effect without actual EQ, and it iwll be much much better. But you will probably use the Eq for small peaks on a few times on somethings because its so hard to make drums cut through, and for me have always been the hardest thing.
The guitars should be 400h-2k dominant. One thing that can really help the the drums (specifically kick) is to cut or even roll off at 4-6k. This loud in your face guitar usually masks out everything in your mix, and doing that helps alot. There should be good warm low mid in this also, but generally roll off at 90h.
Vocals are usually easy from this point on if youve got the right mic. generally compress to come out in front, and something i hear on alot of helcat records is an extreme and compressed high boost in probably 12-16k. This makes it sound extremely bright.
Again, becarefull with masking in the 4k area. Everything is dominant in this frequency. Alternate or try to find the some effect in a different frequencies. Toms usually dont have a problem there, kick should definately get a boost there either by mic placement or EQ. Also, this is what ive found to be the most effective in my style of recording, but it might not be what your looking for.
Mixing, drums and vocals are the most important. They should be the ones in front most of the time, the guitar is usually recorded twice then panned hard left and right. Bass usually blends good with the guitars. It could help to have the bass panned hard left with a 5 second delay panned to the right to help with masking.
Just some tips from my own experience. I will be getting another band in to do some experimenting. They are good friends and so i can usually do some good experiementing but if i get time i will post how it turns out and what i do. I am planning on trying a few new things.

... Anyway one thing I totally disagree with him: I compress everything (yeah really everything - except overheads, cymbals) rather hard. Punk rock is a rather dense kind of music, and I have the impression that it is quite hard to get this sonically dense sound, if your tracks are uncontrolled changing in volume.
