This can work well with 6th, 7th, 9th, 6/9, 11th, and 13th chords. Gearwise, dirt with a clean blend will be your friend if you want to use super dissonant or 5+ note chords with higher gain.
This is good advice. The harmonic relationships between extended intervals are more complex to the ear/brain. Distortion amplifies those harmonic relationships and adds more harmonic overtones. So using complex chords with distortion of any kind creates a very complex network of harmonics that the ear can register as dissonant or mushy. There's just a shit ton going on.. The reason why power chords with lots of distortion works so well is because a root and fifth is a very simple harmonic relationship; there's a lot of room for multiplying overtones. So there are a few ways to work with this.
1. what ck3 says, which is to take out things like the fifth and even the tonic which can be implied harmonically by the rest of the chord or whatever else is going on in the music.
2. keep your chord voicings in a higher register. Because of the way our cochlear is shaped, chords with extended intervals at lower registers sound more dissonant to us than the very same ones at higher registers.
3. Pedalwise, use stuff with even order harmonics and soft clipping. Avoid intermodulated distortions like octave fuzzes and the like. And your clean blend is your friend.
4. It's never going to sound totally clear using complex chords with even light dirt, stop worrying and learn to love the mess.
