Vintage HIWATT Half Stack - If you want BRUTAL TONE but NOT METAL!

I'm playing a 1976 Hiwatt DR103 through a 4x12 with 1960s Fane Pulsonic Purple backs (122/17A) using a Nordin Comet Krystin guitar. I love that this rig (and especially the cab) sounds this aggressive without any Metal vibes!! I'm also playing the cab using a Marshall 1987X and a 2021 Fender Telecaster 1960 Aged Custom Shop.
