Tech Tips from America’s Hottest mixer-Andy Wallace
Well, first of all, I ride them a lot of times because sometimes a cymbal won't be as loud as another cymbal or something. So there's that. But also, in a greater sense — and I think that this is what you're referring to — every cymbal crash will be ridden up maybe 5 or more dB.
Sometimes I will feel that I'm hearing more ambient stuff in the overheads than I want to hear in the mix. So when I get that loud section rocking the way I want, I'll end up with the overheads balanced where I want to hear the ambience and sometimes the cymbals simply won't be loud enough to have the impact that I want.
