Has anyone done this project:
https://sound-au.com/project63.htm
There are two implementations:
https://sound-au.com/project84.htm
In-out stage:
The bandpass module:
https://sound-au.com/project64.htm
Different layout and mixer:
Corresponding mfb module:
I prefer the second one, where we can have single opamps before and after the mfb modules.
I am trying to simulate both, using the values and the calc tool in the website, but neither the frequencies, nor the cut/ boost gain matches with the values of the elements 🙁

I've used these calculators often and found them reliable:

Go to the MFB bandpass, plug your component values and you can establish if the problem is with the calculations in Rod's page or with your simulation. If it's the latter, post it and we can have a look...
