I’m looking for something very similar to 90s Megadeth. Think “Skin of my Teeth.” (Or possibly 90s Metallica or older Black Sabbath or 90s RATM.)
But with mainly the heavy low level bass, and palm muted guitar power cords, without so much of the mids or highs (like vocals and guitar solos.)
Like bass intensive but not super fast like Slayer or double-pedal drum stuff.
Any ideas?
Sounds like you want something like Doom Metal, so I was gonna suggest Candlemass but the vocals are kinda high.
Down has some great riffs and Phil Anselmo’s voice is definitely low, you should try their 2nd album (most interesting for the bass part) : “A Bustle In Your Hedgerow” https://youtu.be/YSdfwOEGFhI
