Wanted to send a shout out to Ola for making me more aware of this, whether he realized it or not. Watching his latest 'Recording guitar tutorial' and watching the section on low-passing at 7kHz made me aware of something I've been subliminally doing for a while now. After the usual '10 to 12kHz' low-pass most of us do on guitars, I always found myself clamping down on everything above 7kHz with the C4. I wondered why, but I was too afraid to drag the low-pass down, thinking I'd eat up too many of the high frequencies. Having finally got the balls to try it for real on a mix, I can just say that it works. It not only is a contributing factor to why you guys like his tones so much, it also brings guitar sounds closer to the crushing variety done by guys like Staub. It even made the guitars closer to the ballpark of good ITB metal sounds, like Gojira's 'TWoAF' which from what I gather is a board favorite. It makes the process of de-fizzing guitars ever so much easier, making the notes more defined and crushing, leaving more space for cymbal articulation and for the high end 'air' of vocals to do its thing. So essentially what I'm saying here is... don't be afraid. Go medieval on those guitas. Limit the bandwidth, give yourself less to work with and less to screw up. I've never understood the fabled '12kHz lowpass' and now I get a chance to move on from there with peace of mind.
