Stoner/DOOM Bassists thread part 37: Ancient Alien Fuzz

#81
yea i dont think its original but how many times have builders done RAT/MUFF/FF/TS stuff so doing another EQ/band fuzz doesnt bother me 2 much. I dont think its nearly as innovative as trying to do some higher voltage JFET stuff like I previosly showed but it is kind of interesting. I didnt wanna do that many knob those. Ecckk

I also did forget about the quadrafuzz tho so yea gotta take ideas with grains of salt.

It's a great list and thanks for opening it up for collaboration. I tossed in a few more. Including shamelessly adding my own band.

When I get a slow day at work I can add a lot more to it. Only real annoying thing about the Spotify playlist is that when you add an album, it doesn't check if it is already in the playlist, and there is no way to tell the playlist to remove any duplicate songs. So if I want to add a bunch of stuff, I have to comb back through the playlist and remove duplicates.

Well half the suggestions we're throwing out here today are useless for any practical application, we see piles of salt and just pour more on. I still like the idea of a multi-band fuzz done right, seems more logical than always depending on a blend feature.

From the perspective of the Stoner/DOOM room, it seems everyone pretty much has their go-to fuzz on lockdown, be it a Bluebeard, Rat Tail, etc. I think thats why the idea of over the top whacky effects are more boner-inducing.

no doubt and some constructive comments are actually quite useful. Id have to breadboard it before I would say it could be useful. I was thinking of the EQ'd fuzz inside of the muff type clipping. So maybe 5 knobs and a few switches to control clipping diodes on each band so if u wanted a clean low end u could get it by reducing the clipping there

Be careful. Muff's sound like ass without enough gain. You get more bass with more gain because the LPF in the feedback loop lets lows through uncompressed by the diodes. As you turn up the gain the highs become more and more compressed and the lows more and more boosted.

You'd be better off with different clipping for each band.

Maybe TS for lows. Muff for Mids. Starved Plate Tube for highs.

you mean the HPF formed by the cap with the clipping diodes. I could also control low end by removing the clipping diodes and running the stage cleaner while mixing in the clipping at higher frequencies, thats almost like clean blend. Its kind of a different approach to the design.

No...I'm talking about the series cab with the Diodes. Not the parallel cap with the feedback resistor.

the cap in front of the diodes forms a HPF which does not allow low end to be clipped by the diodes and thus you retain low end that way. The 470k feedback resistor is not frequency dependent and also provides the base bias for the stage and that collector to bass shunt cap gets rid of high end via feedback.

Since it doesn't clips lows as much and lets them pass I prefer to think of it as a LPF but that may not be technically correct. Maybe we can call it a "Crude Low Passed Clean Blend".

That is the basic theory behind the dirtbox I'm building. mine is based on an actual LPF. I often get turned around by filters in feedback loops. For many of them the operation reverses in the loop.

The lows are still clipped but not as compressed as the mids and highs so the lows sound clearer and bigger. In theory.

This picture is going to be all other this thread...let me know if its annoying yet

your description is correct just that feedback does the opposite of what the filter is called, thats why its confusing. If you feedback high end you cut out high end from the signal or conversely u can interpret that as your low end being unmolested. It might sound like more low end overall in this case.

maybe. I think might try to 4 band EQ idea soon. I would most likely have to change the design of the clipping stages a lot since the EQing of stages is controlled by the 2nd order filters and not the biasing of the stages.
