Extreme noise fuzz pedals

Mountainking Freq LSD might be worth looking at

yeah, I was gonna mention this in my post, but then ennui overcame me

Your best route to achieving multiple sounds at once is really a combination of many effects. Hell, the Metasonix is as you said it was... a MULTI-fx.
As a former owner of several Metasonix and Trogotronic boxes, I can tell you how wonderfully inspirational they are with their multitude of sounds,
but also how incredibly frustrating it can be to get REPEATABLE sounds...
If you had that very pedal sitting right in front of you, I’d be willing to bet you’d still never get those sounds you were asking about.
So, you have to look at what you want and how you want to interface with it.
Do you want to play it like a pedal, having your signal be warped and mangled by the “noise fuzz” but still controllable enough to be recognized as a guitar?
Or are you ok sitting with it for an entire afternoon, gently teasing the knobs and exploring the sonic hellscape that vomits forth, sampler ready to capture “lightning in a bottle”?

If it’s the first one, tons of pedals that have already been mentioned will fit your need.
I’ll toss a few more of my favorites that, admittedly, toe the line:
LAL 88 Super OSCILLO Fuzz
Snarling Dogs Mold Spore
Devi Ever / Dwarfcraft Soda Meiser w/ noise switch
Adventure Audio Dream Reaper
Mountainking Decomposer
Z. Vex Fuzz Factory (the ol’ standby...)

But if you’re feeling more adventurous, then anything can be your noisemaker. A lot of the Metasonix “sound” is achieved by feeding back the signal at various stages in the circuit and then piling up gain stages until they literally fold back on themselves creating that filter-y squelch that makes the hair on the back of your neck stand on end.
You can traverse a similar route with feedback loops (as simple as plugging a two output pedal back into itself) or matrix mixers. You can also delve into circuit bending an old pedal you don’t use anymore.

Remember:

In the era before the boutique noisemakers existed, they did not buy their sounds, but they bent the circuits within themselves.

Page three was the derailing page, and now we are back.

The filter pedal one would want for all that shit is Warm Star Shape Shift Mountain

But the most important thing is that you can literally probably use whatever. This is more drone than noise but the basics of this is a few gain pedals, a scratchy volume pedal and the rv-3 on the sound-on-sound loop mode https://soundcloud.com/sharkmovieappric ... mnb92T3iF8

Yeah I agree with vidret on the lpf thing, they sound too darn nice! My favourite is overdriven bandpasses. Whenever I get bored fucking with synth I switch filter mode to bandpass and its ugly city baby
