I think this sounds more like Tony Iommi. Churchburner fuzz does not provide this attack with palm mutes. Have you switched to another pedal? Can you tell/show about your actual pedalboard/gear in the next videos? Thanks! P.S. Sounds greate!
I have used both hyper fuzz and hm2 style distortion for a while now, to have two different sounds. In the title it says Lichtlaerm Medusa and that is the hm2 style distortion I am using in this video.
