General
The pro-cessor is designed around standard circuits like OpAmp Buffer, Sallen Key Filter etc. The combination is
unique leading to a very flexible workhorse in any effects setup.
Due to your personal needs regarding filtering you will want to choose other component values for the 4
th
grade Sallen
Key filters. The current values will set corner frequencies for the filters as follows:
Lowpass: 250Hz Highpass: 400Hz.
A lot of work has gone into the development of the filtering. The initial idea I had with variable filters (using pots) did
not work as the steepness only is 12dB which was not enough to do efficient frequency cutting.
Now with the 4
th
grade filters there is 24dB action which is highly efficient. Feel free to use other values for your build.
