Hi all-
I Love the OCD circuit. I've built quite a few with Madbean layouts. I run two on my board right now. One of them I have is so much darker than the other in terms of tone and I'm wondering why. Looking for insight as to what parts to start messing around with in the circuit- maybe a capacitor got put in at too high of a value adding more low end? Or would it be something to do with what clipping diodes I used in each?
I dime the presence knob (5 O'clock) on my darker sounding one and it has about the same treble effect as the other one does with the presence knob at about 2 O'clock.
Sounds to me like you might have a different taper on each of those presence pots.
Do you mean this one? And is it one which has darker tone than that another? What is that second device type? The same?

Yeah that schematic- Sorry I forgot to post it.
I'm comparing 2 OCD's to eachother. Ones much darker as mentioned. Same schem from madbean. Pretty sure they're even the same board version.
If you have the same parts with the same values, and the same opamps, then this "dark sound" will be about bad parts in one of them, in tone circuits. Here is question, which of them has that proper sound? That with dark tone, and then we must focus at that second to find wrong part. Or thise dark tone is bad?
