Wow, sounds great. Figured you had a little custom sub under there, but those monitors are really carrying it.

I used to have a sub too but I found it to be unnecessary at least where I play, these have plenty of bass

This thing is sooo nasty! I first thought i dont need yet another filter but this one is really special. Feels more like a mix of fuzz, bit crusher filter and wave shaper. I really love it!

This might be a foolish question, but I have 16v caps for C3 and C4 (the 10uf). Will they suffice, or do I need something like a 35v cap?

should be fine they are filtering 12v supplies so yeah! should be all good

Sweet, thank you! I have a bunch of varying voltages, and as far as I could tell 16v should be fine (Iāve subbed in higher voltage caps in other places), but ehhh wanted to be sure. Iām bound to blow myself up one day.

Iāve a question about this: how can I know the trimmer is in the right position? Do I have to look at the bi-color LED, or do I measure something with my multimeter?

So the Shelf Switch?
I read what Sam put down up there about it, but i am still a little confused. mostly because i only get sound thru this filter when switched down towards the word shelf. is this normal >? I have not tuned the trim pot yet as it seems to be bang on with the red and green signal from the LFO.
with the switch up I can only hear the hiss of the VCA turning up, no signal. my switch is a SPDT ON - ON . I also re-soldered everything and no change. everything else works.
CTorp - in your vid it looks like the switch is up (tho upside down in frame) did i see that correctly?
thanks for you time everyone

Interesting you bring it up. My shelf switch works good when Iām pushing a 3340 oscillator thru it but when i tried using my microkorg it has to be switched down
yeah indeed!!! do you have the offset boost attenuvert? try putting the microkorg through that first. boost on 0 attenuverter on max, and mess around with the offset knob and see how that effects the response of the filter its pretty funky the different types of sounds you will get.
its because I made the 1114 for the 1112ās which are unipolar waveforms, easier to clip and a force of habit from the start but gunna change them to unipolar like things like the microkorg.
so yes the shelf switch is much more useful with the 1112ās above other oscillators, but all it takes is to mess with the offset of oscillators going into the filter to get some interesting effects

Sounds fun! I have the OBA Iāll give it a try

Just tried it out, just a tiny tweak to offset and the korg sounds great thru it. Thanks for the heads up!

Yes hooked just the OBA into the filter with nothing feeding the OBA and put the signal thru the filter in the other input, then tuned the OBA for negative offset, no boost, and both attens centred. now i get signal thru both sides of the shelf switch. thank you. guess i just did not understand how it is supposed to work with offsets. thank you
tweaking the offset can get nice distortions
sounds great.

glad its cleared stuff up for you both! its a cool thing to try with modular playing with where audio waves sit within the voltage range they can sit, it effects the clipping in different ways, all positive or all negative is easier to get it clippy, bipolar obviously has a lot more headroom, so yeah! mess around with offset as a dodgy distortion going into different things.

Is there a way to easily see how the 100k trim pot has to be soldered onto the pcb ?
Mine has this markings - 3 (with cw above) , 2 (in the middle) , 1 (is sitting under the trim pot).
BOM says itās a 3296W and theyāre symmetrical, so it doesnāt really matter, but pin 1 is the one with the trimmer screwhead:
hey pilzfuss the. one on the front best way to do it is like in the other builds like the oscillator one, put it in and dont solder it at the same time you put in the potentiometers. put on the panel make sure the screw terminal on the preset pot fits through the tiny hole in the panel for it and boom!!! if it doesnāt fit oryoucant see it it is probably put in upside down, then you can turn it the righty round, once panel is aligned you can then solder it down

Speaking of that trimmer, is there anywhere about how to calibrate it? Or is it a case of seasoning to taste?

Wow fuck thats crazy ! xD
Thanks for pointing that out samā¦
I really didnt see that hole.
Superb !
Have a nice time !
Itās for zeroing the cutoff cv attenuverterāin the center of the pot you want the cv to have no effect on cutoff. Everything left of center is negative, to the right is positive cv
Put the pot on 12-o-clock and trim until an incoming cv does nothing and the led is off
