Following up on the two Random Source/Serge filters I did a while ago here’s their resonant equalizer.
Straightforward build, but you MUST look at the build guide, there are some components listed on the circuit board that ARE NOT actually installed.
Sounds good, equalizes as you would expect, and has some crunchy resonance. Only potential drawback is that it is a wide module, if you’re tight for space you might want a narrower eq.
