4-Stringed Satan Summoning Saa

Hey there fellas!!! Playin' my 4 string Silvertone on my way to the Pinewood Derby!!! ....tryin to summon Satan..


Fun introductory sentence with a good hook anyways. Since Wednesday I've been trying to manifest what I can only describe as "Satan's Army's Marching Melody." I'm stuck to a cheap beginner 4 string akin to like a Silvertone or First Act. I have a decent little Fender Amp, no effects besides hand made. I've found so many little ways to make this little fella sound like a soul harvesting fire eater, I'm close to what I want. Does anybody have any little tips I might find useful for making a deep and evil hair raising harmony. Wow me please, playing closer to the bridge, bending low E past the nut, muted double slaps, muted hammers/pull offs.... I've put hours into this Satanic Sonet, I'm almost at the point of putting it all together, but I don't want to miss anything.

I'm playing in Drop D (want to be able to bust this out acoustic and scare people that wonder to my fire)
I have been playing like 11 years moderately and HARD recently. I'm well aware of how to manipulate the sounds of my guitar very finely. Any advice is appreciated

PLUS ULTRA!!!!!!!

 

Hahahaha, heck man, I'm asking some pretty technical and specific stuff. Have you never tried to make a bass guitar rumble so evily Satan himself would tap his hoof/hoove...?

 

Haha nice!!! Seems nobody has any tips on heavy, low, evil sounding bass. I do good enough on my own anyways.
