So I've watched this video and it went against a few things I've been doing. Putting a high pass on a bass a thing? I usually set it to like 36-40 ish but I've never set it to the point where it would clear way for the bottom thump of the kick. I usually just have a compressor that ducks about 0.8 db of the bass guitar when the kick hits. I've also never boosted any lows on my Rhy guitar like he did. This is making question what I've learned so far lol, in a good way I guess.
