Mannnnn if I had to pick ONE frequency that continuously gets cut in…. Well, just about any instrument, it would be 350hz! Or 330, or 300, something around there. That range sounds absolutely garbage on just about anything. I’m not saying it needs to be gone from a mix completely, but it sure as hell doesn’t get boosted, and that range sounds absolutely terrible on just about any drum as well.
@anomaly I know what you are saying about guitars being a midrange instrument, all I’m saying is all these arbitrary ideas people come up with about guitars in a mix just doesn’t really equate to how things are in the real world. I can make a guitar sound choked and distant with tons of mids, and cut like a knife with scooped mids. It’s all about the mix. But generally speaking, tones that people think are mid heavy, in general aren’t even close to that. Most modern signal chains have excessive midrange ( 5150, Mesa cab, 808, sm57 for example), and it needs to be cut drastically sometimes to not sound like a bloated body mess. 350-500hz is the enemy of all things guitar, or mixing in general.
