Saturation and distortion are usually used to add bite and roughness to instrumental tracks to help them stand out in a mix. Klanghelm’s IVGI can give you a full spectrum of colors, ranging from subtle saturation and warmth to dirty, grainy distortion. This is a very musical plugin that reacts dynamically to the instrument on which it’s placed, so it doesn’t create any tonal imbalance. You can also control the frequencies that are being saturated to get the detail necessary to make your instruments sound just the way you want.
Here’s an obvious one. The clothes you wear when you’re on stage are a costume and you should think of them as such. Even just wearing your everyday street clothes is going to communicate something to the audience. It sounds annoying and unfortunate, but I guarantee that you do it too when you see a concert: judge a band based on their rags.
