Hey Beeps, good job on controlling things a bit better. Like you thought, the bass is out of control now with low end on my stuff. This is one of those situations where you have to decide whether to drop the low end in the bass or just drop the bass level. In this situation, the bass low end is the problem. Bass guitar doesn't have as much low end as you think it does. When you listen to a mix, you're listening to the sum of everything adding to the over-all low end. I'm still hearing some pumping and the cymbals still sound weird like they are comped to heck. This is probably contributing to what Wookie may be hearing with the "squished" comment.
Next, when he mentions "little definition" this is true because there are good mids missing in this as well as good low mids. The guitars are still too stripped making them not have the definition they could or should maybe have. It's like your missing the elemental frequencies that make mixes more defined and big. Sennheisers are famous for this too...meaning they sort of add things that aren't there as the mids are weird on them. The HD 280 pro's I have here wouldn't help *me* mix anything worth a nickel.
The guitars are decent, but just seem to have the mids gone and are way too razor sharp. I guess what I'm trying to say is...the mix has no body now. If you take away the low end in the bass, we're left with a mix that sounds like an AM radio for the most part. You did control the hiss of the cymbals and turned them down a bit in level which is super important.
The newer mix (I started writing this before I heard the bass fix mix) is the same but with better control over the bass. Everything still sounds way too sharp and abrasive to me bro. There's no body other than the bass like I said. But I like that you controlled the bass rumble better. If I were you, here's what I'd do...
Lower the low end on the bass and try to add some good mids and low mids on the other instruments. Bass has less lows in it than you know, so take some more sub low out or high pass a bit more. I can feel your bass more than I can literally hear the distinctiveness in the bass. It's not about just feeling it....it needs to have an identity and needs to be heard a bit more than felt in my opinion.
The cymbals are better...still a bit sharp/bitey for me and are a bit loud. Remember, they are percussive accents, they shouldn't be as loud as a snare or kick drum. You want them to be heard but you don't want them dominating like you're getting now. Still some sustaining cymbals that are lasting way too long which sound like excessive compression.
The snare is inconsistent. I can hear it pretty good in a few spots, then it totally blends in with the hats from 1:20 to 1:37 and barely sounds like a snare. So that section definitely needs some work.
The guitars are razor sharp and biting too. I know you like that sound, but like I said, if you removed the bass in this, you have no body anywhere else and you could deal with some more body on the guitars as well as the drum kit. They just sound like nothing but high end. Almost on the border of a guitar into an amp sim without speaker emulation. They have no thrust...no punch, just high end sizzle.
So those are the things I'd work on...but only if you yourself can hear them. This is definitely good enough for a bedroom studio demo but there's definitely room for improvement all across the board. You're sort of going in the right direction but need to find out why you're not hearing that the other instruments sound super thin and are lacking body/definition in the low mids and mids. I hope some of this helps.....keep at it man! :)
