Which is where feedback can produce some non-consonant sounds, but it's rare that these sounds don't have a harmonic relationship to the core tone. I find most noise-y pedals tend to still produce consonant overtones, even with feedback.

Anyway. Personally, I prefer tonal feedback, but the last few years I don't really like anything other than clean on an electric guitar. Distorted violin I'm a fan of (Kosugi), and percussion sounds amazing feedbacking. The thing with SY, and Hendrix for that matter, is that they've got superlative control over their feedback, (except in their 'free' sections, obviously) it's very much part of the song
