Hey man.
I used to HPF at 100-150 for guitars (like your rhythm) but I started getting much, much better results by high passing at 80hz, so instead of wiping out the stuff in between 80-150, I would place a nice bell cut in between and just turn it down until you notice the low end clear up. or even low shelf filter, turning it down to the right level is definitely the way to go, those frequencies are important for punch/in your face/warmth/thickness. Wiping out all below 80hz to maybe 100hz on your track is a really good idea though. If there was no bass or kick I'd probably hpf at maximum 80hz, and lower if I could get away with it.
To get the low end right put an EQ on your master and high pass at 300-400hz, balance all of your tracks, not paying as much attention to the low end on kick or snare, bypass EQ. does everything get swamped by the low end and you lose your vocals etc? Well, now you know that there is too much low end, and it is not because the vocal is not loud enough!, cut your low end until your new balance of +600hz starts to poke through again.
That guitar I would start with a low pass filter at 11khz, I LPF typically at 8khz on electrics unless there is something up there I really like. if you like the fuzz up high, keep it there and turn down with a bell cut at 8khz so it's playing nicely in your track, if your fuzz is where you like it volume wise but maybe sounds too piercing or harsh, get a nice bell cut going at 5khz, along with tiny boosts at 350-500 in increments of half db at a time. by the sounds of it you need a hefty cut there at 5khz. maybe as much as 8db, i'm not sure. it depends what EQ you're using. An 8db cut on fabfilter proQ2 or 3 sounds way different to an 8db cut on the waves REQ. and again different to the stock logic EQ(which I don't even bother with anymore)
if you have harsh tracks set up a de-esser (not multiband compressor) and look around 2khz
I think your tracks are pretty good, it's only the electric that stuck out, when I listened earlier on I think that I thought it was too dry/upfront, and far too much highs so needs some "roomverb" to make it seem like it belongs with the rest of the tracks, if you struggle to find a reverb to match the rest, maybe re-amp it back out again and capture some ambience with a room mic in the same room that you recorded the other tracks.
HPF/LPF are helpful but you need to be careful with them. You can use them for more percieved low end on your rhythm guitars, but that is only when you use the HPF along with a boost on the corner cutoff frequency.
I compress everything a little on a track like that, even the distorted guitar, but only 1-2dbs. if there are stray spikes I catch those with a limiter, but only on those sections. Saturation I use all over the place to further control those transients. I compress vocals generally twice via inserts, the first compressor is highest ratio/ fastest atk/rel (limiter settings) to clamp down on wild sections, then an overall smoothing compressor. then set up a send to a bunch of spare busses and apply further processing, parallel compression etc, so the vocal never drops too quiet at any one point in the song, then you need to get creative with distorted delays/ slapback/ vocal thickening etc to make it take a huge step forwards without turning it up, if vocal are still not poking through after all of that then cuts on competing instruments at 2.5-3.5khz along with tiny boosts in the same place on the vocal as long as it doesn't bring out anything unpleasant. then do the same somewhere around 500-1khz(pick anywhere that is least damaging to the rest of your tracks. it's all a compromise. Vocals get compressed the most because I want them up front. Drums don't need any direct compression if you're using drum software, but probably will always use parallel compression, even if it is just automated up during a chorus. Your drum room mic is the exception, it can be cool to heavily squash this. depending on the song. Don't just do it without really listening to make sure you are heading the song into the right direction.
sorry for crappy grammar, pushed for time.
