My 411Hz band is still dead. Switched out caps, resistors and op-amps. Now what?

I would reflow everything. Use a magnifier both to inspect, and while soldering.
Something like this (amazon link)

I'm thinking a doing this build (or just buy a couple of Happy Nerding 3 band para EQa) but I have a few questions:


It has x2 INs and x2 OUTS, can this be used as a pseudo stereo unit?

Have any of you built the break out box for getting the individual bands? IF so, how useful is it/how do you use them?

I would like to be able to use the module almost like a final EQ for tweaking bits here and there subtly as well as for fucking shit up, can it do these things?

The 2 x INs are mixed together, the 2 x OUTs are the even and uneven bands separeted - so you can get pseudo stereo out of it but not process a stereo signal through it.

I have not built a break out box for it, but read somewhere that those who have do not use it very much. I also did not keep the Make Noise Fixed Filter because I did not use the single outs. Processing them with, say, individual delays might be fun, but who has that many delays...

I would not use a resonating EQ as a final EQ on anything. It's not subtle and the bands are not acting independent from each other.

I hope this helped.

You say that like it's a bad thing. :guinness:

Sure, it actually is a good thing, much of what the resonant EQ is about for me. But as a final EQ to 'subtly tweak bits', it would not be my first choice, if any.

Is this a universal view i.e. It is not great for rolling off a dB or two at a problematic freqency?
There are comb outs as well as outputs. How do they differ?
I'm wondering would I be better just grabbing a Happy Nerding parametric 8hp wonder, the Tritone instead if it, too only works in mono?
:hmm:

Nice one Bayer(?)!

I misunderstood your previous post. The two OUTs are just the same - the COMB outputs are representing the two columns of bands and can be used for a (simple) pseudo stereo.

The TriTone is great to just sculpt the sound in a more clean way as in final EQ. It is mono too and sounds much cleaner. Plus it does a nice overdrive if you push it harder.

I use the Serge to color the sound and the Happy Nerding as a clean EQ. Mind that both do not allow to adjust the bandwith while the TriTone allows to adujst the freqeuncy - the resonant EQ is fixed.

How about MI Shelves?

Hi gang,

Couple of questions about this build:

1. Is the feedback circuit completely built into the design? My feedback section seems to do nothing at all, and overall, I cannot get this this unit to howl. Perhaps I misunderstand the feedback section - is it fully internally patched? or does it expect an output to be patched to the input, with the pot controlling the feedback loop?
2. Related to the above: is there a circuit schematic available for this build?

1. The feedback doesn't need any patching. Make sure that the switch isn't set to inverted mode.

2. You can find the schematic here (without the feedback section unfortunately): http://web.archive.org/web/201802010410 ... reseq.html

Ok thank you! Will investigate.

Ha. Missed a couple of 100k resistors like somebody else up-thread. I must have ordered a BOM that was missing 100k resistors.

Anyway. All good now. Spent the last hour just putting a single kick drum through this thing It positively sings. :omg:

How much of a difference do the 1% resistors make here compared with say 5%?

and everybody knows, 4% equals more organic :lol:

Does anyone make something like a Res EQ with voltage control over each band?

Do you think of something like the Verbos Bark Filter Processor?

The Bark isn't resonant though. Maybe the Addac 601 ?

I just got one of these (R*S Res EQ) and damn it's fantastic. a very nice complement to the Bark, very very fun to tweak and keep on the edge of self oscillation.

Yes,
- + individual bands out.
- + 8 in mixer/processor.

Cheers !

Well, i don't know.
I haven't finished mine yet.
But you could try as I do, building it with a CGS202 a CGS04 and ten Thomas Henry / Fonitronik crossfader PCBs (in place of the frequency pots).

Hey all, possibly a silly question but are there any cheaper opamp options for this? Would using something like an 072 work at all?
