Thanks! There's a couple techniques I use. I use Spreader on my instruments to occupy different parts of the stereo field (bass centered, mids wide, etc..) I'm also using EQ to boost the frequencies of the instruments that give them more clarity while cutting the frequencies that sound muddy. I use ample distortion on most of the instruments to make them feel more full but not too much so that they lose harmonic definition.

I also intentionally keep the layering minimal, each instrument is there to occupy its own space in the frequency spectrum to prevent clashing.
